Before buying a forklift truck, you should make certain that it is properly inspected and given a test run. This applies particularly to trucks being bought on line. It is very essential to find potential problems with trucks obtained from companies on-line.
Starting the engine from cold is a great idea. Note whether there is excessive smoke and the ease with which the engine turns over. This is especially vital with trucks that have IC engines.
Testing the performance of the truck in challenging situations should be included in the test run. A skilled driver could operate the truck in reverse and forward, up the ramp.
You can inspect an IC engine truck yourself. On a clear area of floor, run the truck around for a few minutes while a trained operator tests the hydraulic functions. Afterward, examine the ground beneath for indications of fluid leakage. Even seemingly minor leaking could indicate serious problems that would be very costly to fix later on.
A qualified person must check the chains and masts. Check with and without a load that the mast works well. Watch for sticking or 'binding' 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 signs of problems with valve, seals or ram.
If the truck is used, the mast might have been changed at some time. Make certain that the mast and any fitted attachments follow the rating plate on a truck. Check that the sideshift is not sticking when loaded.
When inspecting the forks, look closely at the heel thickness for wear or damage. The manufacturer of the truck specifies minimum thickness. A loose fit could mean the hanger points or carriage are worn. Look for cracks on the arms at heels and mountings.
