Before purchasing a forklift truck, you should make sure that it is properly inspected and given a test run. This applies especially to trucks being bought on line. It is important to find potential problems with trucks obtained from businesses online.
Be sure to start the engine from cold, and note the ease with which the engine turns over and whether there is excessive smoke. This is especially crucial with IC engine trucks.
The test run must include a check of the truck's performance in challenging situations. A trained driver could operate the truck in forward and reverse, up the ramp.
You could carry out your own inspection of an IC engine truck. On a clear part of floor, run the truck around for several minutes while a qualified driver tests the hydraulic functions. Then, look at the ground beneath for signs of fluid leakage. Even seemingly insignificant leaking can result in serious issues that would be very pricey to fix later on.
The chains and masts should be checked by a skilled 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 down or creeping forward of the mast when loaded. These could be symptoms of problems with valve, seals or ram.
If the truck is used, the mast might have been changed at some time. Make certain that the mast and any fitted attachments follow the rating plate on a truck. Check that the sideshift is not sticking when loaded.
Looking closely at the thickness of the heel for wear or damage should be included in the inspection. 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 heels and mountings.
