Prior to buying a forklift truck, you should make certain that it is well inspected and given a test run. This applies especially to trucks being bought on line. It is essential to find possible problems with trucks obtained from companies on line.
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 particularly essential with trucks which have IC engines.
The test run should include an inspection of the truck's performance in challenging situations. A driver who is trained could drive the truck in forward and reverse, up the ramp.
You could inspect an IC engine truck yourself. On a clear part of floor, run the truck around for several minutes while a qualified driver tests the hydraulic functions. After that, look at the ground beneath for indications of fluid leakage. Even seemingly minor leaking can indicate serious issues that would be really pricey to repair later on.
A skilled individual should check the chains and masts. Check with and without a load that the mast works smoothly. Watch for 'binding' or sticking of the mast. A warning sign is play in the mast channels or between the fork carriage and mast. One more is creeping forward or creeping down of the mast when loaded. These can be signs of problems with valve, seals or ram.
If the truck is used, the mast may have been changed at some time. Make certain that the mast and any fitted attachments follow the rating plate on a truck. Make sure that the sideshift is not sticking when loaded.
When checking the forks, look closely at the heel thickness for wear or damage. The manufacturer of the truck specifies minimum thickness. A loose fit could mean the hanger points or carriage are worn. Watch for cracks on the arms at mountings and heels.
