Overhead Crane Risk Assessment

Safety for the Good Operation of the Overhead Crane

In your company or workshop, for your efficiency, convenience, and safety. The cranes or overhead cranes are extremely important to perform the lifting task. They are very useful and popular in most industries; such as construction, metallurgy, mining, oil, chemical industry, production process, transport, rail, storage, logistics, etc.

Workplaces can be in factories, construction sites, warehouses, workshops, garages, iron smelting, port, etc.

Therefore, we want to offer you relevant information for your Crane and Hoist.

Safety rules:

• For each crane, signs of nominal weight must be hung in visible places for all collaborators.
• Check the overhead cranes and their components before starting to operate.
• When the overhead Crane is working, no one should be allowed to be on the bridge
• It is forbidden to use the hook to transport people, it is extremely dangerous.

Overhead crane hazards and control measures

Safe Working Load

For example, if your loads are always 1 ton, you should have a hoist that allows you to load up to 2 tons and not just have a 1-ton hoist, the risk is expensive and is considered an occupational risk.

• The operator without operation ID or under the influence of alcohol can not handle the crane.
• Adopt the necessary security measures according to your country.
• Do not throw things from the crane cabin, it’s dangerous.
• Check that limit switches and protection devices work normally.

• The equipment must be kept clean and orderly.
• Do not leave tools, explosive, flammable, or dangerous materials in the cabin
• Do not come up with food for it.
• Do not overload the crane, you should always consider a surplus before buying and installing the crane and the hoist.
• For the repair and inspection lights, their voltage should be below 36 V.

Restrictions. Equipment and Cranes must not work under the following conditions:

• The load is not tied properly.
• overloaded equipment.
• The signal is not clear.
• drag the goods obliquely.
• explosive, flammable, and dangerous materials without protective measures (unless you have special equipment for this type of load)
• There is great wear for the steel cable.
• the lifting mechanism would be damaged.
• You can not crash between overhead cranes. Do not use a crane to promote the movement of the other.

Functioning:

When the overhead crane is in operation, there should be no obstacle in the production line, and the height of the hook, spreader, and load must be at least 2 m above the ground. If you overcome the obstacles, the extra height must be more than 0.5 m.

Overhead crane inspection

• If you need to perform the inspection or maintenance, you have to cut off the electric power and place a notice for the collaborators. When it is necessary to work with energy, it is necessary to take security measures.
• It is necessary to make the technical safety checks constantly, in addition to planning corrective maintenance services for your hoists and overhead cranes.

Lifting maneuvers:

• For the lifting of very heavy loads, liquid metal, explosives and dangerous materials, you must lift them slowly first up to the height of 100-200mm and test the reliability of the brakes.
• It is not recommended to transport materials over people or machines.

Safety training

• Before use, ensure the crane is suitable for the planned hoisting task. Confirm it has appropriate travel, lift, and capacity.
• Visually and physically inspect the crane before use. Check for damage, wear, and proper operation of all functions.
• Confirm the load weight. Check the capacity of all equipment including the hardware, rope, and slings. Do not exceed these capacities.
• Select the right sling for each lift. Inspect slings and other rigging hardware before use for wear, stretch, or other damage. Do not use damaged or defective slings. Use softeners around sharp corners. Do not splice broken slings.
• When communicating with a crane operator, use clear agreed-upon signals. Except for the stop signal, the crane operator should follow instructions from only one person – a designated signaler. Where a wired or remote controller is used, the operator should become familiar with all of its functions before lifting the load.
• Warn all people in the load lift area before starting the lift. Ensure that the path of the load is clear of persons and obstructions. Do not lift loads over anyone. Center the crane hoist over the load before hoisting to prevent swinging of the load.

Operator training

• Slide the sling fully onto the hoisting hook and ensure the safety latch is closed. Do not load the hook tip or hammer a sling into place.
• Secure unused sling legs. Do not drag slings or leave loose materials on a load being hoisted.
• Keep hands and fingers from being trapped when slack is taken out of a sling. Step away before the lift is started.
• Move the load and controls smoothly. Minimize load swing.
• Walk ahead of the load during travel and warn people to keep clear. Use a tagline to prevent rotation or other uncontrolled motion. Raise the load only as high as necessary to clear objects. Do not ride on the hook or load.
• Set loads down on blocking, never directly on a sling. Do not pull or push loads out from under the hoist.
• Do not leave the load (or the crane) unattended while the load is suspended.
• Where crane operation by other personnel must be restricted, employ lockout and tagging procedures.
• Store slings off the floor in a clean, dry location on hooks or racks. Do not leave slings, accessories, or blocking lying on the floor.

Overhead crane inspection

Overhead cranes can be an integral part of a facility’s productivity. If a shop crane is out of service for even just an hour it can have a domino effect throughout the whole facility. That’s where inspections on the overhead cranes can be a critical service to keep the crane (and shop) running smoothly.

Most facilities will call in a company that services overhead cranes or an overhead crane service company.

Overhead crane service

Overhead crane service companies are great at servicing the electrical and mechanical components but they may not have the expertise or experience in structural inspections. That’s where a crane inspection company should be involved.

They have the experience and the tools to do a proper structural inspection. Also, if there are defects discovered during the inspection, crane inspection companies have the experience and knowledge of how to do a proper repair.

Overhead crane maintenance

What happens when there are structural defects in an overhead crane?

It’s not uncommon to find structural defects on an overhead crane. If a defect is not found in a reasonable timeframe it could propagate into a structural failure. If a crane is taken out of service due to a structural defect it could be inoperable for a couple of days for repairs.

It’s best to catch these defects before they become a major issue. A small repair can be performed in an hour and a large repair could have the crane shut down for a couple of days.

When a structural crane inspector checks an overhead crane they are looking for cracks in welds, deformed structural members, and other defects that could affect the structural integrity of the crane.

They will look at the columns that support the crane way to make sure they don’t have any defects. The most common defect on the columns are dents that occur when a forklift or other machinery accidentally hit the column.

Next is the crane way itself. Once again the inspector will check for any defects in the structural members and welds. It is important for the inspector to have access to the full length of the crane way for a thorough inspection.

The Bridge will be checked for defects including looking for any negative camber in the bridge beam. On the trolley, they will be looking for any structural defects and check the wire rope for any deficiencies.
