Prior to buying a forklift truck, you should make sure that it is properly inspected and given a test run. This applies particularly to trucks being acquired on line. It is vital to detect potential issues with trucks bought from companies on the World Wide Web.
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 especially essential with trucks that have IC engines.
The test run must include an inspection of the truck's performance in challenging situations. An operator who is qualified can operate the truck in reverse and forward, up the ramp.
You can inspect an IC engine truck yourself. On a clear part of floor, run the truck around for a few minutes while a qualified driver tests the hydraulic functions. Then, examine the ground underneath for indications of fluid leakage. Even seemingly insignificant leaking can result in serious issues which would be expensive to fix later on.
The chains and masts should be inspected by a trained individual. Check with and without a load that the mast operates smoothly. Watch for 'binding' or sticking of the mast. A warning indication is play in the mast channels or between the mast and fork carriage. Another is creeping forward or creeping down of the mast when loaded. These can be symptoms of problems with valve, seals or ram.
If the truck is not new, the mast might have been changed at some time. Make sure that the mast and any fitted attachments adhere to the rating plate on a truck. Make certain that the sideshift is not sticking when loaded.
When checking the forks, look closely at the heel thickness for damage or wear. The truck's manufacturer specifies minimum thickness. A loose fit can mean the carriage or hanger points are worn. Look for cracks on the arms at heels and mountings.
