A crane is a highly important, if not essential machine for any work site. Being able to lift and manoeuvre large objects quickly and safely, the crane can increase efficiency and productivity substantially, whether it’s being used to unload cargo, shift construction material or for use in a warehouse.
But you should never underestimate just how dangerous a crane can be if used when it’s not in proper working condition. Unfortunately, accidents do happen on the job, and sometimes there’s nothing we could have done to stop them. What we can do is to take every possible measure to ensure our team members are protected and that they’re working in as safe an environment as possible. That’s why it’s so important for a crane operator to look after and maintain his or her lifting equipment as much as possible. In this article, we’ll be looking at some of the things that need to be done as far as maintenance of a crane goes.
Daily Inspections
The crane operator should check over the condition of the crane daily, checking the structure for any potential rust, cracks, or loose parts. This also includes testing the emergency equipment and operational controls on the machine to ensure that it is working properly. Ultimately, a daily inspection can save any mishaps happening while the crane is being operated.
Major Inspections
Major inspections should also be scheduled from time to time, or whenever necessary. These focus on the aspects of the crane that cannot easily be detected during routine daily checks; the engine, the controls, etc. A major inspection takes quite a bit longer, so it might be better suited to schedule them on days when the crane isn’t being used. You should look at the crane’s:
- Controls: Test the levers and wiring for any potential problems that compromise the performance of the crane. The brakes, boom angle and load measuring instruments should also be examined and tested.
- Structure: Check the body of the crane comprehensively for any faults and wear in the structure of the crane including loose plates, bolts or rust. In addition, check the engine, gearbox, brakes and clutch to ensure they are in good condition.
- Hydraulics: Check the hydraulic system for any wear or leakage that comes with continued use. Inspecting motors, pumps and air cleaners should also be a priority.
- Wire ropes: Wire ropes should be unwound, checked and relubricated or replaced if necessary. Also, make sure the ropes haven’t been stretched and lengthen, as this can be problematic.
Repairs
Regular inspections can reveal if any repairs are required, in which case they will need to be dealt with by an experienced technician. If you or one of your people is doing the repairs, remember that it’s extremely important to observe safety precautions at all times. This includes wearing protective clothing. The cranes should not be turned on under any circumstances while it is being worked on and main switches should be turned off. Parts can be sourced from crane suppliers around the country and overseas, and these should be as close to the previous part as possible. Speak to the manufacturer of the crane if you need advice in regards to part replacements.
Obviously, proper maintenance of lifting equipment requires good awareness. If the machine doesn’t feel as if it’s operating correctly, it pays to stop and take a look. There should be no compromise when it comes to the safety of your worksite, so you should take every step to ensure your lifting equipment is in the best possible working condition.
