Prior to buying a forklift truck, you must make sure that it is properly checked and given a test run. This applies especially to trucks being acquired on-line. It is essential to find possible problems with trucks acquired from companies on the Web.
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 vital with IC engine trucks.
The test run must include an inspection of the truck's performance in tough situations. A skilled operator could operate the truck in reverse and forward, up the ramp.
You could check an IC engine truck yourself. On a clear area of floor, run the truck around for a few minutes while a trained driver tests the hydraulic functions. After that, look at the ground beneath for signs of fluid leakage. Even seemingly minor leaking could result in serious issues which will be expensive to fix later on.
The masts and chains should be checked by a qualified person. 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. Another is creeping down or creeping forward of the mast when loaded. These can be signs of issues with valve, seals or ram.
The mast might have been changed at some time if the truck is used. Make certain that the mast and any fitted attachments adhere to the rating plate on a truck. Make sure that the sideshift is not sticking when loaded.
When inspecting the forks, look closely at the heel thickness for damage or wear. The truck's manufacturer specifies minimum thickness. A loose fit can mean the hanger points or carriage are worn. Watch for cracks on the arms at mountings and heels.
