Prior to buying a forklift truck, you should ensure that it is correctly inspected and given a test run. This applies particularly to trucks being bought on line. It is essential to find potential problems with trucks bought from companies on the Web.
Starting the engine from cold is a good idea. Note whether there is excessive smoke and the ease with which the engine turns over. This is especially essential with trucks which have IC engines.
The test run must include an inspection of the truck's performance in challenging situations. A skilled driver could drive the truck in reverse and forward, up the ramp.
You can carry out your own inspection of an IC engine truck. 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 beneath for indications of fluid leakage. Even seemingly minor leaking can indicate serious issues which will be costly to repair later on.
The masts and chains should be checked by a skilled 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 fork carriage and mast. Another is creeping down or creeping forward of the mast when loaded. These could be signs of problems with ram, valve or seals.
The mast might have been changed at some time if the truck is not new. Make sure that the mast and any fitted attachments adhere to the rating plate on a truck. Check 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 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.
