A forklift must be inspected properly and given a test run prior to purchasing it. This applies particularly to trucks being purchased on the Internet. It is important to find potential issues with trucks obtained from businesses on line.
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 specifically vital with IC engine trucks.
The test run must include an inspection of the truck's performance in tough situations. A driver who is qualified can operate the truck in reverse and forward, up the ramp.
You can check an IC engine truck yourself. On a clear part of floor, run the truck around for a few minutes while a trained driver tests the hydraulic functions. Afterward, look at the ground underneath for signs of fluid leakage. Even seemingly insignificant leaking could indicate serious problems that would be very costly to repair later on.
A qualified individual must check the masts and chains. Check with and without a load that the mast works smoothly. Watch for sticking or 'binding' of the mast. A warning sign 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 could be symptoms of problems with valve, seals or ram.
The mast might have been changed at some time if the truck is used. Make sure that the mast and any fitted attachments adhere to 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 wear or damage should be included in the inspection. The truck's manufacturer specifies minimum thickness. A loose fit can mean the hanger points or carriage are worn. Look for cracks on the arms at mountings and heels.
