Crane inspection is a necessary aspect of regular maintenance to ensure that the crane is safe to operate. Any neglect of regular inspection can result in a costly error and unnecessary liability for a company. There are several steps that may be required for a crane inspection, but none of them should ever be overlooked. Some of the steps for crane inspection only need to be performed on a semi-regular basis, while other steps for inspection need to occur on a daily basis. If you aren’t sure, you should contact your crane manufacturer or Canadian Custom Electrical for more information about your particular crane model.
Below are some details about the different parts of the crane that should be inspected and maintained on a regular basis:
- Trolley – The trolley is crucial to the proper operation of the crane and it must be inspected regularly. Areas of the trolley that may need to be inspected include the sheaves, trucks, gear drive, grease fittings, the gear case oil level, and lube condition.
- Hoist – The hoist is another major area of the crane that needs regular inspection, and the parts include the gearing system, couplings, bearing covers, and sheaves.
- Load Block – Inspection of the load block should include looking out for broken wires, checking for rope deterioration, corrosion, damage in the sheave nest, wear in the rope, and the hook rotation. It is also important to check for any wear in the hook and note it as soon as it occurs.
- Bridge – The bridge inspection should include the end trucks, the idler, wheel flange, and a check for any loose bolts on the motor or other parts of the bridge. The oil levels in the gearbox should be checked as well, and the seals and grease fittings should be inspected.
- Wheels – The wheels should be checked for wear and replaced when needed. The wheel bearings should also be inspected along with the wheel flanges. Also keep the wheel grease bearings full.
- Brakes – Brakes should be examined on the hoist, trolley, and the bridge and replaced whenever needed. The brake shoes and pads should be inspected for wear, and the disc brakes should be checked to ensure that they are activated even when there is no power to the machine.
- Cab – The cab of each crane model will vary, but inspection requirements can include checking the foot brake, having a fire extinguisher in close proximity, checking any warning lights or other indicators, checking the radio and the transmitter, and the transfer switch and panel.
By no means is this an exhaustive inspection list, but these are some of the areas of an overhead crane that will be inspected on a regular basis. For more information on the parts that should be inspected for your overhead crane, and a schedule for how often they should be inspected, always contact your crane manufacturer or a crane company like Canadian Custom Electrical for more information on the proper steps that are required and the best schedule for your crane model.
