In order to help avoid the need for expensive lift truck repairs, it is suggested to inspect the front end of your forklift frequently as part of your pre-shift and even daily examination. By catching any problems ahead of time or as they occur, you can also help prevent damage to any type of loads too. The following includes several of the common guidelines on what particular things to check during frequent inspections of your material handling fleet.
Forks
It is vital 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 lift truck must immediately be removed from service until it is fixed and safe once more. Visually check your forks for any visible signs of wear or damage. If the cracks run deeper than on the surface, replace them. Any kind 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 up and down. You might need to grease 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 each side. The lift bracket side rollers are a different lubrication point and there is also one on every side roller. When the lubricating has been done, tilt it forward and backward and also lower and raise the mast a few times in order to ensure that the lubricant is worked properly into the fittings.
Tilt Cylinders
Uncontrolled mast movement could be caused by oil leakage; therefore, your inspection should include checking for oil leaks and for damage. Whether the leaks are external or are situated inside of the cylinder, the end result can be cylinder drift and loss of fluid. If there are any signs of leaks or damage, you might have to replace just the seals or the entire cylinder assembly.
Chains
Check and make sure that the mast chains are not stretching beyond their acceptable limits. Also be certain to inspect the chains for signs of wear or damage utilizing a chain wear gauge. If there is wear beyond 2 percent, replace the chain. Also replace it if the chain looks rusted or kinked. Both the sheave bearings and the chain rollers must also be checked for signs of wear.
Typically, mast lift chains wear at the pin-to-link connections. If you discover wear, you could experience chain failure. This can end up damaging front end components or even the product. If you need help determining what precisely to check on your lift trucks or if you do not have time on hand to perform regular fleet inspections, just call your local lift truck dealer. Their skilled service technicians will help your perform PM or planned maintenance inspections based on your scheduling and application needs.
