Prior to purchasing a forklift truck, you must make certain that it is properly inspected and given a test run. This applies specifically to trucks being obtained on line. It is vital to find possible problems with trucks bought from companies online.
Be sure to start the engine from cold, and note the ease with which the engine turns over and whether there is excessive smoke. This is especially vital with trucks which have IC engines.
Testing the performance of the truck in challenging situations must be included in the test run. A trained operator could maneuver the truck in reverse and forward, up the ramp.
You can inspect an IC engine truck yourself. On a clear part of floor, run the truck around for a few minutes while a trained driver tests the hydraulic functions. Then, examine the ground beneath for signs of fluid leakage. Even seemingly insignificant leaking can result in serious issues which will be costly to fix later on.
A trained individual should inspect the masts and chains. Check with and without a load that the mast works smoothly. Watch for 'binding' or sticking of the mast. A warning sign 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 could be signs of issues with valve, seals or ram.
If the truck is not new, the mast may have been changed at some time. 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 damage or wear should be included in the inspection. The manufacturer of the truck specifies minimum thickness. A loose fit might mean the hanger points or carriage are worn. Watch for cracks on the arms at heels and mountings.
