Before buying a forklift truck, you must make certain that it is correctly checked and given a test run. This applies especially to trucks being bought on-line. It is very important to detect potential problems with trucks purchased from businesses 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 too much smoke. This is particularly essential with IC engine trucks.
The test run should include a check of the truck's performance in tough situations. A driver who is qualified could maneuver the truck in forward and reverse, 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. After that, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking can indicate serious issues that will be expensive to repair later on.
The chains and masts must be inspected by a trained person. Check with and without a load that the mast works smoothly. Watch for sticking or 'binding' of the mast. A warning indication is play in the mast channels or between the mast and fork carriage. One more is creeping down or creeping forward of the mast when loaded. These could be signs of problems with valve, seals or ram.
The mast may have been changed at some time if the truck is not new. 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 damage or wear. The manufacturer of the truck specifies minimum thickness. A loose fit could mean the carriage or hanger points are worn. Watch for cracks on the arms at heels and mountings.
