A forklift must be inspected correctly and given a test run prior to purchasing it. This applies particularly to trucks being acquired on the Web. It is vital to detect potential problems with trucks acquired from companies on line.
Be certain to start the engine from cold, and note the ease with which the engine turns over and whether there is excessive smoke. This is specifically crucial with trucks which have IC engines.
The test run must include an inspection of the truck's performance in tough situations. An operator who is trained can maneuver the truck in reverse and forward, up the ramp.
You can perform your own inspection of an IC engine truck. On a clear part of floor, run the truck around for a few minutes while a qualified driver tests the hydraulic functions. Then, look at the ground beneath for indications of fluid leakage. Even seemingly insignificant leaking can indicate serious problems that would be very pricey to fix later on.
The chains and masts must be inspected by a qualified person. 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 mast and fork carriage. One more is creeping forward or creeping down of the mast when loaded. These could be symptoms of problems with valve, seals or ram.
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 certain 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 can mean the carriage or hanger points are worn. Look for cracks on the arms at mountings and heels.
