The Basics of Ergonomics for Overhead Cranes

As a business owner, you often think of your industry in terms of the big picture. You must create professional networks, meet industry standards and plan for the future of your business.

However, no matter how large your endeavor becomes, you must also be aware of small details that can have a large impact. One of these small details is the safety and comfort of your employees during regular working conditions.

In industrial and commercial industries, these individual employee needs may be combined together under the category of “ergonomics.” In this context, ergonomics includes all measures taken to reduce the physical and mental stress on employees in a particular position.

In this blog, we discuss the importance of ergonomics in industrial settings, specifically for overhead lifting equipment operators. We also provide an overview of how employers can make overhead lifting equipment more ergonomic for their workers.

Operating an Overhead Crane in Extreme Weather

As an overhead crane operator, you’re dealing with a powerful machine that can lift more than 30,000 pounds. But you’re also dealing with a dangerous piece of equipment that could cause serious problems if something goes wrong.¬†

Your experience and training can help you prevent everyday crane problems. But are you prepared to handle abnormal weather conditions? Without preparation, the wrong weather situation could damage your crane and endanger you and your coworkers.

Pay attention to these extreme weather conditions and take the necessary precautions.

Lightning

Because overhead cranes tower high into the air, they have a high risk of getting struck by lightning. You should not use your overhead crane if there is any lightning in the area. A simple way to know if you’re in danger of a lightning strike is if you hear thunder. You could use a lightning detector to pinpoint the exact location of the lightning.

As soon as you’re alerted to the presence of lightning, turn off the crane’s electrical power and lower the boom. Then make sure all your coworkers take shelter far away from the crane and any other metal equipment.

When the lightning has ceased, that doesn’t mean you can immediately head back to work. Inspect the overhead crane for any damage before you resume your project. High temperatures from a lightning strike can cause the crane’s rope to melt, so you must change the crane’s rope after any lightning strike.

Rain

Even when lightning isn’t a factor, rainy conditions can damage your overhead crane. Water can enter different parts of the crane, including the clutch and the brakes. The water can damage these parts and prevent your crane from working properly.

During a construction project, time and money are always huge considerations. However, you should think twice before you carry on your project in the rain. It’s better to move your crane to a sheltered area if possible and wait until the rain subsides.

Just as you would do after a lightning strike, inspect your overhead crane after a rainstorm for any signs of damage.

Wind

Wind is arguably the most dangerous type of weather for overhead cranes. Wind can cause the crane’s load to swing. This effect can put unnecessary strain on the crane and could even cause it to drop the load.

Each overhead crane comes with a wind rating, indicating the highest speed of wind it can withstand. A general recommendation is that overhead cranes shouldn’t operate in winds of more than 20 miles per hour.

As you operate the crane in windy conditions, pay attention to how the wind affects the crane at any given moment. If wind hits the underside of the boom, it can reduce the crane’s backward stability. If wind hits the rear of the boom, it can reduce the crane’s forward stability.

Keep in mind that if you’re operating the crane between two buildings, the wind speed can increase. Also, the higher the crane is lifting, the higher the wind speed is likely to be.

Cold Weather

When you think of “extreme weather,” you probably don’t first think of cold weather. However, cold weather can have a huge impact on overhead cranes. Cold temperatures can reduce the crane’s tensile strength and can even cause it to fail.

An overhead’s hydraulic system can weaken in cold weather. Thus, you should reduce your load weight by 25 percent in subzero temperatures. If the weather is colder than -20 degrees F, reduce the load weight by 40 percent.

Other cold weather precautions include:

  • Surrounding the trolley with an enclosed track to protect it from ice
  • Adding a cold weather finish to the crane
  • Using conductor bars to protect the crane’s joints
  • Investing in a cold-weather motor

Snow and extremely cold temperatures are dangerous conditions to operate a crane. You should exercise extreme caution under these conditions.

Heat

Although it’s not as dangerous as cold weather, heat still poses a risk to your overhead crane. For one, heat can decrease the effectiveness of your crane’s seals. Broken seals can lead to other broken parts. Thus, it’s crucial not to expose your crane’s seals to direct sunlight, especially in hot weather.

Another heat-related problem is dust, which often forms in hot conditions. If you don’t clean and maintain your crane’s filters, dust and dirt can wreak havoc on your crane. It’s important to regularly clean and lubricate your crane’s parts as well.

Operating an overhead crane can be dangerous under normal circumstances. When extreme weather comes into play, the potential for danger multiplies. Use these guidelines to protect yourself, your employees, and your equipment during extreme weather.

So You Want to Be a Crane Operator: 6 Facts About Training

When you think about the work that goes into new construction, you may picture concrete contractors laying a foundation, framers putting up studs, or electricians wiring the building. One of the most frequently overlooked but also most sought after construction occupations is that of the crane operator.

As the job title suggests, a crane operator lifts and moves materials on industrial, commercial, and building sites. This job requires excellent depth perception, communication abilities, and understanding of specialized equipment.

In this blog, we discuss six characteristics of crane operation and qualified operator training that people who wish to join this employment sector should know.

Before You Lift: 6 Top Safety Tips For Crane Operation

Safety is important in any industry, but in crane operation, safety is paramount. Cranes have the power to lift loads that weigh thousands of pounds. Any mistakes in operating them can cause serious injury and even death.

As a crane operator, safety should be your priority. Following safety tips protects your equipment, your coworkers, and everyone around your work site. Here’s what you need to do before operating a crane.

Does Your Crane Need Repairs? Look for These 7 Signs

When it comes to industrial equipment, cranes are as strong as they come. A tower crane, for example, can lift up to 18 metric tons, or 39,690 pounds.

Occasional repairs are necessary to maintain your crane’s powerful structure. After all, a malfunctioning crane presents a huge safety concern to both construction workers and passersby.

To decrease your risk of crane problems, have a qualified crane inspector inspect your crane regularly. But problems could still arise in between inspections. Thus, you should keep an eye out for any of the following issues.
