Overhead Crane Inspection Guide

Hand signal guide for crane operators

Being prepared is the best way to avoid an accident, and this is especially true when it comes to overhead cranes. OSHA has found that an average of 71 crane-related fatalities happen each year. In most of these cases, an inspection could have identified the fatal problem before tragedy struck. That’s also not counting the thousands of less-serious accidents involving cranes that could have been prevented if the equipment had been subjected to the required inspection. Although these accidents may not result in the loss of life, they can result in injuries as well as serious fines for safety violations and costly downtime.

Regularly inspecting overhead crane equipment is one of the most important steps companies can take to cut down on these unfortunate crane-related incidents. However, it is crucial that operators and supervisors do more than give their equipment a quick glance to see if everything simply looks all right. Overhead crane equipment must be put through a rigorous and thorough inspection process before it can be cleared for safe crane operation. What’s more, there are dozens of inspection points that must be checked during these inspections. Additionally, certain inspection points must be checked on a more frequent basis than others, so it is essential that operators and supervisors understand OSHA’s requirements for these inspections. The following crane guide illustrates many of the most important inspection points on overhead crane equipment. By following it, companies can help ensure that their equipment and their job sites will be much safer and better prepared.

6 Things to Do to Curb Crane Accidents at Construction Worksites

6 Things to Do to Curb Crane Accidents at Construction Worksites

Construction sites have stringent safety protocols in place to prevent adverse events and accidents. Even with all the precautions and preventive procedures, fatal injury rate for the industry is quite high. This can be attributed to a number of reasons ranging from oversight on part of site managers to malfunctioning equipment. Another probable cause is the sheer size of the industry where at any given day more than 6.5 million people are at work at work sites numbering an approximate 252,000.

Cranes cause significant and serious injuries if they are not inspected and checked before use for defects. Fatal injuries can occur if an untrained person operates a crane or if the crane is not used properly. There are several recommendations put forth by Occupational Safety and Health Administration (OSHA) that try to mitigate worker safety issues while using a crane.

Tower and mobile cranes are most commonly used in construction sites. Here are a few things that you need to know in order to avoid accidents in your work site.

  • How Do Injuries Occur?

Grievous injuries occur both on and off-site when a crane collapses or when a worker is struck by overhead load. Accidents and fatal injuries also occur when a worker comes in way of a crane’s swing radius, cranes come in contact with a power line or conductor, or when cranes collide with each other.

All of these present possibilities of multiple injuries and fatalities.

Ill-planned and ill-executed crane operations cause delay and obstructions at the construction site, and also cause accidents.

Ensure you follow safety rules and adhere to user instructions. Being scrupulous about adhering to safety rules is the best thing you can do to avoid worksite accidents.

  • Plan Well

Crane operations need to be planned in advance to avoid mishaps. A trained and experienced person has to evaluate the site conditions and address the risks present. Crane operator and other crew members must be aware of potential hazards in the worksite and other unusual operating conditions. The required resources, procedures to be followed and responsibilities of personnel need to be worked out.

Lifting equipment including slings and other accessories should of adequate strength to carry out the operations. They should be tested and inspected for quality. They have to remain safe for the entire range of jobs and period of operations.

  • Follow Safe Work Protocols

It is important to check crane controls and signalling arrangements before commencing work. Wire ropes, chains, hooks and all rigging systems should be checked for strength and efficacy. The load being lifted should not exceed the rated capacity for the make and model of your crane and lifting equipment.

Failure of brake systems is another reason behind work site accidents involving cranes. Raise the load a bit and check the effectiveness of the brake system before launching operations.

Properly trained and competent personnel should operate the crane. They must have prior experience handling similar job role and responsibilities.

Cranes should not be operated without approval of a higher authority. Also there should be a competent authority supervising crane operations who can signal the user if anything goes wrong.

  • Evaluate the Ground Conditions

Many incidents occur at work sites when cranes tip over due to poor or unstable ground conditions.

In addition to ground anomalies a range of other factors also result in cranes tipping over. The outriggers of mobile cranes need to be fully extended or as specified by the manufacturer. When this is not done cranes tip over.

Insufficient counter weights and wind also cause accidents. Another cause behind cranes tipping over is wrongly calculated loads that exceed crane capacity.

Ensure that cranes operate under optimal conditions to avoid worker injuries and fatalities.

  • Maintain a Safety Zone

If possible, it is recommended to maintain a barricaded safety zone to prevent entry of unauthorized people into the lift area. People, structures and other equipment that come in the crane’s swing radius cause accidents and worker injuries. Such incidents occur when the path of the load is not clearly planned and when cranes operate in crowded or high traffic areas.

This is applicable while using overhead cranes in industrial environments as well.

  • Carry out Inspections Regularly

OSHA publishes safety and regulatory rules that need to be followed when operating cranes at construction sites.

Inspections have to be carried out on shift, monthly and annual basis for crane equipment and wire ropes. Post-assembly inspections are mandatory to ensure that cranes are in optimal working condition. Pre-erection inspection is necessary for tower cranes. Four-year inspections for key components like vessel or floatation device is also recommended by OSHA.

Safety and reliability of crane operations depend as much on the user as on the crane hirer. When a crane is hired, planning, supervising and operating responsibilities fall on the user, unless explicitly expressed otherwise.

Conclusion

Safety and security of crane operations depend on a number of factors. It is important to ensure that crane equipment and accessories are maintained well. If you follow the cranes standard set by OSHA, you will be able to reduce accidents at work site drastically.

 

Some Tips To Select The Right Crane

some tips to select the right crane

These valuable tips will help you select the right crane for your project

Cranes have been used by humans from a long time. Now, work in almost any industry is impossible without cranes. If you have a project that would require the use of a crane, you need to research about what kind of crane would serve the purpose.

The information that you require would be related to proper load rating of the crane, the type of ground where the crane has to operate and other factors. You would need all of that information before reaching a decision on which crane to use.

Crane tips has brought numerous knowledgeable articles for its readers and it keeps providing quality information. This article presented here is in the form of a series of questions and answers that would help you reach the right decision about your crane.

Read the complete article to learn how to select the right crane!

The questions and answers related to the topic are presented below:

How High is the Work to Be Done?

The height of the work is going to impact how the boom is set up, as well as what kind of boom will be necessary. Furthermore, the extension of the crane’s boom can be affected by the wind, which increases exponentially as the height increases. In addition, the amount of counterweight needed to heft loads to ever-increasing heights needs to be calculated differently versus if the height is lower. Tower cranes now have dramatically higher capacity than they once did, and they can often lift over 1,000 meters into the air.

What Material and Condition is the Ground Beneath the Crane?

Cranes need a solid support structure beneath them to support the load and to keep their movement stabilized. While truck mounted cranes are often useful when there is concrete to support the crane itself, outriggers are sometimes not enough on unstable terrain. Rough terrain cranes offer the necessary mobility for grass or dirt surfaces without compromising most of the strength. When there is an uneven substrate, you need to consider the width of the crane’s base.

What Kinds of Obstacles are There?

In many environments, especially urban and suburban ones, cranes need to be adapted to circumventing obstacles. In addition to winds, there may be power lines, other buildings and other obstacles that can keep a crane from being able to simply raise the load directly from its origin point to its destination. In some instances, even the control scheme the crane uses can be difficult in the presence of obstacles, with pendant station cables getting caught. Radio controls may be more effective and less potentially hazardous.

How May the Crane Affect the General Public?

Just like how tower cranes are affected heavily by windy weather, the public in the area the crane is operating may be affected by this operation. If the crane’s size impacts the flow of traffic beyond a reasonable threshold, this can cause problems for the entire construction site. Further, if the crane is likely to cause issues with the operation of nearby buildings, this needs to be taken into consideration prior to selecting the type of crane you are going to use for your project.

Tips To Handle Construction Risk

Some tips to handle construction risk

Some handy tips to help you handle construction risk

Construction has always been a very prolific field. It has continued to be an ever-green field with numerous jobs for people with different backgrounds.  In addition to being a great field, construction also has certain risks that other fields do not have. In fact, it may not be wrong to say that construction is one of the riskiest fields out there.

Crane Tips is all about cranes and construction. We deeply care about our valuable readers and that is the reason we share great information with all of you on a regular basis.

As stated above, construction is indeed a difficult and risky field but the risks in construction can be handled and lowered by employing some tips and following certain strategies.

The strategies to manage the risks in construction are presented here, so that you can handle the project in a safe and wise manner.

Do not miss out the golden tips to manage construction risk by reading the complete article!

Allocate Risk

The contract negotiation and preparation phase is the best time for all project leaders, including the owner, contractors, architects, and building manager, to come together and anticipate all potential risks and assign responsibility of those risks to parties most apt to handle them should the unwanted arise. For example, the building owner and architect should be charged with ensuring design and environment issues are worked out and should draft a plan in case something arises. Meanwhile, contractors should be charged with ensuring personnel are equipped with all the necessary safety guidelines and understand how best to maneuver the environment with equipment in a safe and secure manner.

Managing Funding Risks and Feasibility Risks

These two types of risks are commonly described as “invisible risks” as they are rarely apparent until they are, in which they change the entire game. Yet, with careful preparation and research, most undertaking construction tasks can avoid them.

The first, feasibility risks, arise most commonly out of environmental issues that were not fully addressed in the original plan proposal. They include things like:

  • Extreme weather-based delays
  • Unforeseen factors of a specific location
  • New issues with coding and zoning laws

The ‘Management’ in Risk Management

Finally, it is important to note that this article is entitled with “managing construction risks” because the critical lesson here is not how to avoid all unwanted occupancies, but how to cope with the inevitable. Here, you research, prepare, and assign. Understand all of the potential issues with a construction project, consult with the available experts and professionals, set aside budgets to deal with funding risks, and ensure you have the right insurance in place before signing contracts.

Some Things You Must Learn Before Buying LED Light Bars

You must learn these before buying LED light bars

These are a few things you must learn before buying LED light bars

A good lighting is very important if you have a factory or facility where works need to be done uninterrupted day and night. The best solution in such a case is to opt for LED light bars. Similarly, if you have the soul of an adventurer and you want to explore and roam around the terrain in your ATV, 4×4 vehicle or motorcycle, then LED driving lights are your best bet. The reason behind using LED light bars and driving lights is simple; they are absolutely the best solution available in the market. Crane Tips has always been concerned with the safety of its readers, especially those in the construction sector or crane business. We have always provided great quality content to our valuable readers and that is the reason we have also selected this particular article which explains a few things that one needs to know before buying LED light bars. Interested in getting the perfect lighting solution? You need to read the complete article to learn more!

Lumens, not watts

Forget what you know about incandescent lamps — your watts are no good here. When shopping for bulbs, you’re probably accustomed to looking for watts, an indication of how bright the bulb will be. The brightness of LEDs, however, is determined a little differently. Contrary to common belief, wattage isn’t an indication of brightness, but a measurement of how much energy the bulb draws. For incandescent lamps, there is an accepted correlation between the watts drawn and the brightness, but for LEDs, watts aren’t a great predictor of how bright the bulb will be. (The point, after all, is that they draw less energy.)

You’ll pay more for an LED light bar

LED light bars are like hybrid cars: cheaper to operate but pricey upfront. When switching to LED light bars, don’t expect to save buckets of cash. Instead, think of it as an investment. Luckily, competition has increased and LED light bars have come down in price but you should still expect to pay much more than an incandescent light. Eventually, the LED light bars will pay off, and in the meantime, you’ll enjoy less heat production and longer lifespan.

Hand Signal Guide For Crane Operators and Crew

Hand signal guide for crane operators

This hand signal guide is for crane operators to work safely

Crane operators must be very skilled and need to be trained properly so that they can perform their jobs efficiently and safely. While working on any site, the operators also require some assistance from the crew or workers present on the site.

The work sites are usually bustling with life, energy and activity during a project and are often so noisy that you cannot communicate easily. People use radio sets or walkie talkies to reach out to each other in such places.

Crane operators are professionals who are entrusted with the loading, movement and carrying of various heavy objects as a part of their daily activities. It is very important to guide the operators during the crane operation to ensure there are no accidents.

We ensure to keep providing you good tips for crane operation and so we have taken a wonderful and important article from TNT Crane & Rigging so that you can get benefited by this valuable information.

The crew or workers must use their hand signals to guide the operators to ensure safety during the process. This article is comprised of definitions and explanations of different hand signals that can be used in order to help the crane operators.

Read the complete article to learn more about this important topic!

Here are the different hand signals used for crane operation, along with their explanations:

Use Main Hoist

There are going to be occasions when the main hoist is necessary for its greater strength. In these instances, the signaler cocks their right arm outward and bends their elbow outward, which allows the signaler to tap on their hard hat with their closed hand as if they were knocking on a door.

Use Whip Line

On some occasions, the whip line or fast line may be preferable to the main hoist. To signal using the whip line, the signaler places his/her left arm horizontally across the front of the body, palm upward. The signaler then makes a forward-facing fist with the right hand, and puts the right elbow into his/her left palm in front of themselves.

Raise Boom

To raise the boom, the signaler begins with the right arm outstretched to the side. From there, the signaler points the thumb upward.

Lower Boom

To lower the boom is the reversal of the signal to raise the boom. The signaler begins with the right arm outstretched to the side. From there, they point their thumb downwards.

Swing

It can be necessary to turn or swing the crane. In these instances, the signaler extends the right arm straight outward to the side, with the palm facing downward.

Extend Boom

The boom or primary arm of the crane, must sometimes be extended for its reach. In some cases the boom can be extended independently of lowering or raising it. When the boom must be extended, the signaler places his/her closed hands on either side of their body at hip height, with both thumbs facing outward.

Retract Boom

Retracting the boom can often exert greater leverage with better stability than when the boom is extended. When the boom must be retracted, the signaler places their closed hands at around waist height, with thumbs pointing inward toward their body.

10 Tips for Better Mobile Crane Operations

10 Tips for Better Mobile Crane Operations

 

1. Never override the mobile crane’s computer.

2. Be aware of all overhead hazards – specifically close-by buildings and any power lines that are within the zone of operation.

3. Read the load charts – prior to turning the key in any new mobile crane.

4. Cell phones in the cab – while the crane’s key is on the cell phone is off.

5. Always note the changing conditions on the jobsite – from personnel to weather to surroundings. If you work at night, ensure the proper lighting is in place to ensure 100% safety.

6. Sometimes in a working situation, the crane operator needs to stop, evaluate, and find a safer lift plan.

7. Check ground conditions – before crane setup, ensure that the site is suitable to support your mobile crane and the future suspended loads.

8. Use appropriate pads & cribbing – mobile crane operators need to make sure they are using correct pads or cribbing to avoid having an outrigger fail or sink when they are making a lift.

9. Before starting your crane, always double check the oil, gas, and other fluid levels.

10. At the beginning of your shift, walk-around your crane checking for mechanical, electrical, structural, and hydraulic issues (MESH).

Mobile crane operators are a small brotherhood whose main goal is to ensure the safety of those we are working with. If we can avoid a few simple operating errors, it will go a long way in avoiding an incident on the job site.

Zoomlion Tower Cranes Erect Pavilion at Expo 2017

With the recent Expo 2017 coming to Astana, Zoomlion placed and used multiple tower cranes to erect the pavilions main buildings.

The building has a diameter of 80m and a height of 100m, with pavilions of other countries evenly distributed around it in a ring shape.

Twelve large-tonnage Zoomlion tower cranes, seven Zoomlion truck cranes and one Zoomlion bulldozer have participated in the pavilion construction.  “Among which four Zoomlion D1100-63, the super-large tower cranes with the maximum hoisting capacity in the Central Asia,” said the manufacturer.

The D1100-63 is a new model of self-climbing tower crane, featuring superstructure slewing, double lifting points, level jib and horizontal trolleying. With a hoisting capacity of 9.8t at the 80m jib end, the tower crane adopts variable frequency stepless speed-regulating motor to significantly optimize the system’s running stability and improve positioning accuracy.  PLC (programmable logical controller) is used to control all actions.

The event will take place between June 10 and September 10, 2017.

This was the second time that Zoomlion has been involved in Expo construction, having helped to build the Chinese Pavilion in Expo 2015 Milano.

Zoomlion said: “The direct economic and trade cooperation and cultural exchanges between China and Kazakhstan are of far-reaching significance to promote the development of the “Belt and Road” [Chinese government-backed investment and trade strategy]. As a leading enterprise in the engineering machinery industry, Zoomlion has explored the market in Kazakhstan for over ten years, dedicated to efficiently helping the construction of local infrastructures.”

Cranes are Construction Machines Not Toys

The recent ‘climb’ in the number of people trying to scale tower cranes in metropolis’s around North America is getting ridiculous. As reported by the Barrie CTV news, the numbers are ever increasing.

The number of people climbing multi-storey cranes in York Region is a growing concern for emergency crews.

On Sunday night, two 16-year-olds were spotted at the top of a 13-storey construction crane in Newmarket. The teens climbed down and were arrested for mischief and trespassing.
“It seems almost crazy that we have to be here to warn people about the dangers of climbing cranes, construction cranes, but nevertheless here we are,” Const. Andy Pattenden told CP24.

“People, primarily youths, have been climbing these multi-storey construction cranes,” Pattenden said. “It’s happening at night. They’re going out there, the reason for which we’re still not sure why they’re doing it – probably for thrill-seeking, something from YouTube. They’re gonna climb up and take a selfie at the top of these cranes.”

Between May 22 and June 11, police have dealt with four cases of people climbing cranes. These have happened in Richmond Hill, Whitchurch-Stouffville and Newmarket.

Parents are being asked to speak with their children about the dangers.

We couldn’t agree more.

Common Overhead Crane Hazards and Their Prevention

Overhead Crane Hazards Along With Their Prevention

Cranes are fascinating machines and are essential for almost every kind of industry. Without cranes, it is impossible to work efficiently. Overhead cranes are used primarily used in production units or manufacturing industry. There are some dangers associated with overhead cranes. This piece of writing is focused on explaining the dangers and the ways to prevent them.

Read the complete article to learn more about overhead crane hazards and their prevention!

Some Common Overhead Crane Hazards and Tips On How to Prevent Them

Preventing Overhead Crane Hazards: In any type of industry, the coming together of anticipation and pro-actively handling problems is something, which does result in greater success than just reactively responding to incidents. If an individual works in the world of construction and manufacturing, there are hazards always present at job sites, but with proper training and preparation ahead for them, a lot of issues can be prevented.

Potential Electrical Hazards

About 50% of all crane accidents that happen overhead can be attributed to machinery coming into contact with a power source of some kind during operation. Typically, why this occurs is because, as a crane moves materials close to or beneath energized power lines, the hoist line or boom gets into contact with the electrical source. This is an issue, which is about half of all hazards that are associated with these overhead cranes, and it can be stopped with good safety planning.

In addition to this, make sure to ask electrical companies to de-energize or to ground any existing power lines when there are individuals working in close proximity to them. However, until specifically informed by the electrical company, all operators should assume that all power lines are energized and extremely dangerous. A final preventative measure is to make sure all ladders, tools, and other systems being used on the work site aren’t at all conductive.

Any Materials Falling

One of the best ways to lessen the chance of any materials falling down from cranes is clear. It is to make sure to perform regular maintenance of hoists. An example of this is to do load testing maintenance to ensure that you know how many pounds a hoist can handle exactly.

Here at TNT Crane Service, Inc., we always make sure to put safety and prevention first. It is our number one priority. Because of this fact, we ensure that all the machines we have are kept well maintained and up to date. What this does is ensures that you will be getting the most effective, as well as, the most reliable equipment that is available. Please view the equipment that we have on hand for sale or rental today. It may help you to find the crane that you require for your next major project coming up.
