In order to help avoid the need for expensive lift truck repairs, it is suggested to check the front end of your lift truck regularly as part of your daily and even pre-shift examination. By catching any problems as they occur or in advance, you could also help avoid damage to any cargo as well. The following includes a few of the general guidelines on what specific stuff to inspect during regular inspections of your material handling fleet.
Forks
It is essential to regularly inspect the forks because if they are worn out or cracked, they could probably fail without warning. Any kind of fork damage means that your forklift must instantly be removed from service until it is fixed and safe once again. Visually check your forks for any noticeable signs of wear or damage. If the cracks run deeper than on the surface, replace them. Any type of wear on the forks beyond 10 percent is another indication that you should replace the forks.
Mast
The mast should ideally tilt backward and forward while being able to move down and up. You might need to lubricate the mast strip sliding surfaces and fittings if you find that the sliding surfaces are binding. On the inner mast there is a fitting situated on every side. The lift bracket side rollers are a different lubrication point and there is also one on each side roller. When the lubricating has been completed, tilt it backward and forward and also lower and raise the mast several times in order to guarantee that the lubricant is worked properly into the fittings.
Tilt Cylinders
Uncontrolled mast movement could be caused by oil leakage; therefore, your inspection must include inspecting for damage and for oil leaks. Whether the leaks are located inside of the cylinder or are external, the end result could be loss of fluid and cylinder drift. If there are any signs of leaks or damage, you may have to replace just the seals or the whole cylinder assembly.
Chains
The mast chains need to be inspected to see if they are being stretched beyond their acceptable limits. Also, check the chain wear guage or check the chains for signs of damage. If there is wear beyond 2 percent, replace the chain. Also replace it if the chain appears kinked or rusted. The chain rollers and the sheave bearings must also be checked for signs of wear.
The mast lift chain will typically wear at the pin-to-link connections. You could experience chain failure if you notice wear. This can end up damaging the product or front end components. If you require help determining what exactly to check on your forklifts or if you do not have time on hand to carry out frequent fleet inspections, just call your local forklift dealer. Their trained service technicians would help your perform planned maintenance or PM checks according to your scheduling and application requirements.
