Prior to purchasing a forklift truck, you must make certain that it is correctly checked and given a test run. This applies particularly to trucks being purchased online. It is very essential to find potential problems with trucks purchased 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 too much smoke. This is particularly essential with trucks which have IC engines.
Testing the performance of the truck in tough situations should be included in the test run. A trained operator can 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 qualified driver tests the hydraulic functions. Then, examine the ground beneath for signs of fluid leakage. Even seemingly insignificant leaking can lead to serious problems which will be costly to repair later on.
A trained person must check the chains and masts. Check with and without a load that the mast operates smoothly. 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 down or creeping forward of the mast when loaded. These can be symptoms of issues with seals, ram or valve.
If the truck is not new, the mast may have been changed at some time. Make sure that the mast and any fitted attachments adhere to 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 truck's manufacturer 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.
