A forklift should be inspected properly and given a test run prior to buying it. This applies specifically to trucks being obtained on-line. It is very vital to find potential issues with trucks obtained from companies on the Internet.
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 particularly essential with trucks that have IC engines.
Testing the performance of the truck in tough situations should be included in the test run. A driver who is qualified could drive 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 several minutes while a trained driver tests the hydraulic functions. Afterward, look at the ground underneath for signs of fluid leakage. Even seemingly minor leaking can result in serious problems that will be pricey to fix later on.
A qualified individual must check the masts and chains. 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.
The mast might have been changed at some time if the truck is used. 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 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. Look for cracks on the arms at mountings and heels.
