Prior to purchasing a forklift truck, you must ensure that it is properly inspected and given a test run. This applies especially to trucks being obtained online. It is important to detect possible issues with trucks obtained from companies on the World Wide Web.
Starting the engine from cold is a good idea. Note whether there is too much smoke and the ease with which the engine turns over. This is particularly vital with IC engine trucks.
Testing the performance of the truck in challenging situations should be included in the test run. A driver who is qualified can operate 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 qualified driver tests the hydraulic functions. After that, examine the ground beneath for indications of fluid leakage. Even seemingly minor leaking could indicate serious issues which would be pricey to repair later on.
A trained individual must inspect the masts and chains. Check with and without a load that the mast works well. Watch for sticking or 'binding' of the mast. A warning sign is play in the mast channels or between the mast and fork carriage. Another is creeping down or creeping forward of the mast when loaded. These could be signs of issues with ram, valve or seals.
If the truck is used, the mast might 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.
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 hanger points or carriage are worn. Watch for cracks on the arms at mountings and heels.
