The Ministry of Manpower (MOM) and the Workplace Safety and Health Council (WSHC) of Singapore emphasised that the stakeholders within the crane and lifting equipment industry are responsible for the safety and reliability of cranes used in the workplace. Compliance with legal requirements likewise plays a role in the safe operation and management of cranes.
Whether you operate or own cranes, you need to ensure that they comply with statutory requirements and are safe. That is where equipment maintenance and inspection can help. You should allow a company that offers crane servicing to do the maintenance and inspection for you. Wong Fong Engineering explains that while you wait for help to come, you can conduct your own pre-maintenance check.
Here are some of the important parts of a crane that you should look at:
Hydraulic Systems and Wire Rope
In the hydraulic system, check whether the air cleaners need cleaning or replacement. Make sure the motors, pump, and hoses are working properly and have no defects to ensure an effective and safe operation.
As for the wire rope, inspect all of its hardware, including the thimble joints, dead-ends, sockets and sheaves. The rope should be well lubricated to prevent the core from drying out.
Monitoring Devices and Control Mechanism
You should also check if the crane is used according to the manufacturer’s manual. Proper operation of the anti-two block system, boom length indicator, boom angle indicator and load moment indicator should be observed.
Control mechanisms, such as levers, brakes and cables, should be checked for excessive wear or poor adjustment. Check if the marking on the load/radius indicator over full range is working properly.
Crane Structure and Accessories
Crane servicing likewise includes inspection of the structure and boom of the crane for corroded, cracked or deformed parts. Be sure to remove, replace or repair loose rivets or bolts, worn parts of the brake and clutch system, deformed wedges, and any defective guardrails, pins and cotter keys.
Hiring a company that offers crane inspection services can help you meet all associated requirements and ensure proper and safe working condition of your crane, as well as maintain its availability and capability.
