Prior to purchasing a forklift truck, you should ensure that it is well checked and given a test run. This applies specifically to trucks being acquired on line. It is vital to find potential problems with trucks bought from companies on line.
Be certain to start the engine from cold, and note the ease with which the engine turns over and whether there is too much smoke. This is particularly essential with trucks which have IC engines.
Testing the performance of the truck in challenging situations should be included in the test run. A driver who is trained could maneuver the truck in reverse and forward, up the ramp.
You can inspect an IC engine truck yourself. On a clear area of floor, run the truck around for a few minutes while a trained operator tests the hydraulic functions. Afterward, look at the ground beneath for signs of fluid leakage. Even seemingly insignificant leaking can indicate serious issues which would be costly to repair later on.
The chains and masts should be checked by a skilled individual. Check with and without a load that the mast works well. Watch for sticking or 'binding' of the mast. A warning indication 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 can be signs of problems with seals, ram or valve.
If the truck is not new, 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.
Looking closely at the thickness of the heel for damage or wear must be included in the inspection. The truck's manufacturer specifies minimum thickness. A loose fit can mean the carriage or hanger points are worn. Watch for cracks on the arms at mountings and heels.
