Prior to purchasing a forklift truck, you should make sure that it is properly inspected and given a test run. This applies specifically to trucks being bought on the Internet. It is important to find potential issues with trucks obtained from businesses on-line.
Be certain to start the engine from cold, and note the ease with which the engine turns over and whether there is too much smoke. This is specifically essential with IC engine trucks.
Testing the performance of the truck in tough situations should be included in the test run. A trained operator could drive the truck in reverse and forward, up the ramp.
You could check an IC engine truck yourself. On a clear area of floor, run the truck around for a few minutes while a skilled driver tests the hydraulic functions. After that, examine the ground beneath for indications of fluid leakage. Even seemingly minor leaking can indicate serious problems that will be very expensive to repair later on.
A qualified person must inspect the chains and masts. 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 mast and fork carriage. One more is creeping down or creeping forward of the mast when loaded. These can be signs of issues with valve, seals or ram.
If the truck is used, 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.
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 could mean the hanger points or carriage are worn. Look for cracks on the arms at mountings and heels.
