A forklift should be inspected well and given a test run before purchasing it. This applies especially to trucks being acquired on the Web. It is vital to find possible problems with trucks purchased from businesses online.
Be certain to start the engine from cold, and note the ease with which the engine turns over and whether there is excessive smoke. This is specifically vital with trucks that have IC engines.
The test run must include an inspection of the truck's performance in tough situations. An operator who is trained could operate the truck in reverse and forward, up the ramp.
You can carry out your own inspection of an IC engine truck. On a clear area of floor, run the truck around for a few minutes while a qualified driver tests the hydraulic functions. After that, look at the ground underneath for indications of fluid leakage. Even seemingly insignificant leaking can indicate serious problems that would be very expensive to fix later on.
The chains and masts must be inspected by a trained person. Check with and without a load that the mast operates smoothly. Watch for 'binding' or sticking of the mast. A warning sign is play in the mast channels or between the mast and fork carriage. Another is creeping forward or creeping down of the mast when loaded. These could be symptoms of issues with valve, seals or ram.
The mast may have been changed at some time if the truck is not new. Make certain that the mast and any fitted attachments adhere to the rating plate on a truck. Check that the sideshift is not sticking when loaded.
When inspecting the forks, look closely at the heel thickness for wear or damage. The manufacturer of the truck specifies minimum thickness. A loose fit might mean the hanger points or carriage are worn. Watch for cracks on the arms at mountings and heels.
