Before purchasing a forklift truck, you should make sure that it is properly inspected and given a test run. This applies especially to trucks being acquired on-line. It is really vital to detect possible issues with trucks bought from companies on the Internet.
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 crucial with trucks which have IC engines.
Testing the performance of the truck in tough situations must be included in the test run. A trained operator can maneuver the truck in forward and reverse, up the ramp.
You can inspect an IC engine truck yourself. On a clear part of floor, run the truck around for several minutes while a qualified driver tests the hydraulic functions. After that, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking could result in serious issues which would be pricey to fix later on.
The masts and chains must be checked by a skilled person. Check with and without a load that the mast works smoothly. Watch for 'binding' or sticking of the mast. A warning indication 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 signs of problems with seals, ram or valve.
If the truck is used, 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 wear or damage. 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.
