Prior to buying a forklift truck, you should ensure that it is properly inspected and given a test run. This applies especially to trucks being bought on-line. It is vital to detect possible problems with trucks purchased 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.
Testing the performance of the truck in tough situations should be included in the test run. A qualified driver could drive 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 several minutes while a trained operator tests the hydraulic functions. Then, examine the ground underneath for indications of fluid leakage. Even seemingly minor leaking can indicate serious problems that will be very costly to repair later on.
A qualified person should inspect the chains and masts. Check with and without a load that the mast operates well. 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 down or creeping forward of the mast when loaded. These can be signs of issues with seals, ram or valve.
If the truck is not new, the mast may have been changed at some time. Make certain 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 must be included in the inspection. The manufacturer of the truck specifies minimum thickness. A loose fit can mean the carriage or hanger points are worn. Watch for cracks on the arms at mountings and heels.
