In order to help prevent the need for costly lift truck repairs, it is recommended to check the front end of your forklift frequently as part of your daily and even pre-shift inspection. By catching any problems ahead of time or as they happen, you could also help avoid damage to any cargo too. The following covers some of the general guidelines on what specific things to check during regular inspections of your material handling fleet.
Forks
Regularly checking the forks is vital because if these are worn out or cracked, they may fail without warning. Any type of fork damage means that your lift truck should instantly be removed from service until it is repaired and safe once more. Visually inspect your forks for any noticeable signs of damage or wear. If the cracks run deeper than on the surface, replace them. Any type of wear on the forks beyond 10 percent is one more sign that you should replace the forks.
Mast
Ideally, the mast should tilt forward and back and be able to smoothly move down and up. If you find that the sliding surfaces are binding, you may need to lubricate the mast strip sliding surfaces as well as their fittings. On the inner mast there is a fitting located on each side. The lift bracket side rollers are another lubrication point and there is also one on every side roller. When the lubricating has been done, lower and raise the mast and also tilt it forward and backward a few times in order to guarantee that the lubricant is worked correctly into the fittings.
Tilt Cylinders
Your daily inspection needs to involve the checking for oil leaks and damage as an uncontrolled mast movement can be a result of oil leakage. Whether the leaks are located inside of the cylinder or are external, the end result may be cylinder drift and loss of fluid. If there are any signs of damage or leaks, you might need to replace the entire cylinder assembly, or just the seals.
Chains
Check and make certain that the mast chains are not stretching beyond their acceptable limits. Also be certain to inspect the chains for signs of wear or damage using a chain wear gauge. If there is wear beyond 2 percent, replace the chain. Also replace it if the chain appears rusted or kinked. Both the chain rollers and the sheave bearings also have to be checked for indications of wear.
Typically, mast lift chains wear at the pin-to-link connections. If you notice wear, you could experience chain failure. This can end up damaging front end components or even the product. If you do not have time on hand to perform frequent fleet inspections or if you need help determining what exactly to inspect on your lift trucks, simply contact your local forklift dealer. Their skilled service technicians will help your perform planned maintenance or PM inspections according to your scheduling and application requirements.
