Prior to purchasing a forklift truck, you should make certain that it is correctly inspected and given a test run. This applies particularly to trucks being acquired on-line. It is really vital to detect possible issues with trucks purchased 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 specifically vital with IC engine trucks.
The test run must include a check of the truck's performance in tough situations. A driver who is trained could maneuver 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 indications of fluid leakage. Even seemingly insignificant leaking could result in serious problems which will be costly to repair later on.
A trained individual should check the masts and chains. Check with and without a load that the mast operates well. Watch for sticking or 'binding' of the mast. A warning indication 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.
The mast may have been changed at some time if the truck is used. Make sure 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 manufacturer of the truck specifies minimum thickness. A loose fit might mean the carriage or hanger points are worn. Look for cracks on the arms at mountings and heels.
