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 purchased on line. It is really important to find potential issues with trucks obtained from businesses 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 especially essential with IC engine trucks.
Testing the performance of the truck in tough situations should be included in the test run. A skilled operator could operate the truck in reverse and forward, up the ramp.
You could carry out your own inspection of an IC engine truck. On a clear part of floor, run the truck around for a few minutes while a trained driver tests the hydraulic functions. After that, look at the ground underneath for indications of fluid leakage. Even seemingly minor leaking can lead to serious problems which would be very pricey to repair later on.
The masts and chains should be inspected by a trained individual. Check with and without a load that the mast works well. Watch for 'binding' or sticking of the mast. A warning indication is play in the mast channels or between the fork carriage and mast. Another is creeping forward or creeping down of the mast when loaded. These can be symptoms 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.
When inspecting the forks, look closely at the heel thickness for wear or damage. The truck's manufacturer 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.
