Before purchasing a forklift truck, you should make sure that it is properly inspected and given a test run. This applies specifically to trucks being obtained on the Internet. It is vital to detect possible issues with trucks purchased from businesses on line.
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 particularly vital with IC engine trucks.
Testing the performance of the truck in tough situations must be included in the test run. An operator who is qualified can 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 skilled driver tests the hydraulic functions. Afterward, examine the ground beneath for signs of fluid leakage. Even seemingly insignificant leaking can result in serious problems which will be expensive to repair later on.
The chains and masts must be checked by a skilled individual. Check with and without a load that the mast operates smoothly. Watch for 'binding' or sticking of the mast. A warning indication 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 can be symptoms of issues with valve, seals or ram.
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.
When inspecting the forks, look closely at the heel thickness for damage or wear. The truck's manufacturer specifies minimum thickness. A loose fit can mean the hanger points or carriage are worn. Watch for cracks on the arms at heels and mountings.
