A gantry crane operation procedure is an essential part of any crane maintenance program. It helps prevent damage to the equipment and ensures the safety of all employees. The operator must first check the indicating devices to ensure they are accurate. The operator should also check the slings for more than two legs, oil leaks, and damaged hoists. The operator must also make sure that the full weights of containers are displayed for easy reference.
Check for oil leaks
The first step in ensuring a safe gantry crane operation is to conduct a visual inspection. Operators should check for signs of major damage and out-of-order signs before starting operations. Operators should also inspect under the crane for loose objects and parts. Additionally, operators should check for any signs of oil leaks from the crane's parts. In addition, the operator should make sure that the drum is properly spooling or reeving the wire rope.
Before starting operations, operators should make sure that the control cable and load chain are free of damage. They should also check the pushbutton and pendant to ensure that they are properly functioning. Gantry crane manufacturers provide operators that should also check the labeling on the pendant and pushbuttons to ensure legibility. Before starting operations, operators should press the pendant's buttons to test all the movements. Operators should also make sure that the E-STOP button is pressed to shut off the power. Also, operators should check the pushbutton and pendant buttons to make sure that they are free of stuck or loose. Lastly, they should check the pushbutton dust cover to make sure that it is not torn or has been damaged.
Operators should carefully check the crane's rated load capacity to ensure that the lifting capacity is not exceeded. Operators should also test the brakes if the crane is operating close to capacity. They should also check that the hoist hooks are secure and have a safety latch that automatically closes. Operators should never lift a load higher than the hoist's working load capacity. The operator should always balance the load, and the operator should never attempt to lift a load over a person or other equipment. Operators should also never allow people to ride on the load or hook. Operators should not leave the controls unattended while lifting a load, and they should never allow workers to operate the crane without supervision.
Operators should also take note of any other signs of oil leaks. Poor maintenance can cause oil to leak and affect the safety of the crane. Properly cleaning the joint surface is essential to preventing oil from leaking. In addition to improperly cleaning the joint surface, improper installation of the sealant can cause oil leaks. Proper maintenance and inspection will prevent oil spills from disrupting production.
Operators should check the gantry crane for oil leaks frequently. OSHA requires visual inspections of overhead cranes prior to operation to ensure maximum safety. Workers must also check for warning labels that are easily read by all workers. The crane should not be leaking oil or liquid, and its braking system should operate properly. The chain hoist and hooks should also be checked for damage or wear. Finally, workers should check the nylon or synthetic web slings for wear and tear.
Check for damaged hoist
The first step in safely operating a gantry crane is to check for damaged hoists. The hoist must be free of damage and be in working condition before you can use it. If you find any damages, contact qualified maintenance personnel to have them repaired. Likewise, if you notice that the load is not balanced, lift it a few feet before attempting to lower it.
The next step is to check the control cables and pendant for damage. You should also test the hoist's upper limit switch. When you check the limit switch, make sure the crane is off, and if the hoist is not working, it is safe to disconnect the power. Ensure that there are no loose wires or cables in the control box. If you notice that the switch is not operating correctly, contact the person responsible for the hoist.
Next, inspect the wire rope and load chain. Check for any wear or corrosion. Make sure there are no nicks or dents. The hoist should not be damaged unless the rope breaks. Also, inspect the hoist's travel limit switches and other warning lights. If any of them are damaged, you must remove them before operating the gantry crane. If they are functioning correctly, the crane can safely be operated.
Before operating the gantry crane, you must check the hoist. The wire rope must be free of bird caging and other damages. Chain hoists must also be free from cracks, gouges, and excessive wear. You should also check the chain guides and upper and lower sprockets. Chain hoists should have a properly functioning hook latch. Also, make sure the hooks are not twisted or deformed at the throat opening.
If the electric hoist hook does not stop at both ends, it is time to change it. In this case, the hook may be loaded too heavily. In addition, the electric hoist may have a broken wire or an open lowering circuit. Lastly, the contactor or motor may not be working properly. If the motor is faulty, you must adjust the limit switches to ensure the crane is operating safely.
Another major cause of crane accidents is improper securing of the loads. When the load is not secured properly, it may tip over, crashing to the ground below. Alternatively, a mechanical failure may result in the heavy load falling down. For this reason, it is crucial to perform daily inspections to ensure that the hoist is in safe working order. In addition, you must always remember to perform lockout/tagout procedures to prevent accidental movement of the crane.
If the electric hoist hook fails to respond to the pendant, you may need to repair it. Check the load brake to see if it has become stuck or is slipping. If so, you should replace it as soon as possible. Alternatively, you can simply check for damaged hoist components. You must consult the owner's manual for detailed instructions. If you are not sure what to do, you can contact the manufacturer of the crane.
Check for slings with more than two legs
Slings with more than two legs are unsafe. The crane's operator must inspect slings for any damage or deterioration prior to use. Observe the sling's angle, length, and weight to ensure proper load distribution. The angle should be greater than 45 degrees, and the horizontal distance between the attachment points and the load must be less than the length of the shortest leg of the sling.
It is also important to check for slings with more than two feet during gantry crane operation procedure. Slings with more than two legs are more likely to snap or break under the load. This can cause serious hazards, and the rigged load must be secured properly. Several methods must be used to secure the load to the gantry, and each method must be carefully followed. A goliath crane manufacturers is a manufacturer or a company that is engaged in the manufacturing of goliath cranes.
Slings should be checked regularly during gantry crane operation procedure. Slings must be checked for breaks, splices, and defects. Slings should only be used when the crane is correctly rigged and balanced. A crane should not exceed its limit of 2 tons (4000 pounds). Also, the weight of the load should be properly recorded on scales.
A thorough inspection of the equipment is the best way to ensure its safety. If there are any defects, it is important to correct them immediately. The equipment should undergo monthly or yearly inspections to ensure safety. Operators must follow the limitations and specifications specified in the owner's manual. Always keep the load safe during operations. Once the proper load is secured, crane operators can lift the load.
Before lifting, the load must be properly rigged on the gantry crane. Make sure the load is centered over the hoist and that no obstructions or hazards are blocking the path. Slings with more than two legs should be checked during the gantry crane operation procedure. The lift line must be horizontal before the load is lifted. Make sure the personnel are cleared from the lifting area. The load must also be seated correctly on the slings.
Slings with more than two legs should be checked for damage before use. Any signs of stretching, nicks, or gouges should be noted and replaced immediately. If there are any problems with the sling, the operator should immediately contact a qualified technician. In addition, the operator should follow the manufacturer's recommendations to extend the lifespan of the sling.
