In order to help avoid the requirement for costly forklift repairs, it is recommended to check the front end of your forklift frequently as part of your pre-shift and even daily examination. By catching any problems as they arise or in advance, you could also help avoid damage to any loads 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
Frequently checking the forks is key because if these are worn out or cracked, they may fail without warning. Any kind of fork damage means that your forklift must instantly be removed from service until it is repaired and safe once more. Visually inspect your forks for any visible indications of damage or wear. If the cracks run deeper than on the surface, replace them. Any wear on the forks beyond 10 percent is another indication that you should replace the forks.
Mast
Ideally, the mast should tilt back and forward and be able to smoothly move up and down. If you find that the sliding surfaces are binding, you may have to lubricate the mast strip sliding surfaces as well as their fittings. 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 every side roller. Once the lubricating has been done, lower and raise the mast and also tilt it backward and forward a few times in order to guarantee that the lubricant is worked into the fittings properly.
Tilt Cylinders
Uncontrolled mast movement can be a result of oil leakage; thus, your inspection should involve checking for damage and for oil leaks. 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 leaks or damage, you might need to replace the entire cylinder assembly, or just the seals.
Chains
The mast chains have to be checked to see if they are being stretched beyond their acceptable limits. In addition, inspect the chain wear guage or check the chains for signs of damage. If wear is present beyond 2 percent, replace the chain. Also replace it if the chain seems kinked or rusted. Both the sheave bearings and the chain rollers must also be inspected for signs of wear.
Usually, 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 require help determining what exactly to inspect on your forklifts or if you do not have time on hand to carry out frequent fleet inspections, just contact your local lift truck dealer. Their skilled service technicians will help your perform PM or planned maintenance inspections according to your scheduling and application requirements.
