Before buying a forklift truck, you should make sure that it is well checked and given a test run. This applies especially to trucks being purchased on line. It is vital to find possible issues with trucks obtained from businesses on-line.
Starting the engine from cold is a great idea. Note whether there is too much smoke and the ease with which the engine turns over. This is particularly crucial with trucks that have IC engines.
The test run must include a check of the truck's performance in tough situations. A trained driver can maneuver the truck in forward and reverse, 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 trained driver tests the hydraulic functions. Afterward, look at the ground underneath for indications of fluid leakage. Even seemingly minor leaking could lead to serious issues that will be very pricey to repair later on.
A skilled person must check the chains and masts. Check with and without a load that the mast works well. Watch for 'binding' or sticking of the mast. A warning sign is play in the mast channels or between the fork carriage and mast. One more is creeping forward or creeping down of the mast when loaded. These could be symptoms of issues with seals, ram or valve.
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 truck's manufacturer specifies minimum thickness. A loose fit might mean the carriage or hanger points are worn. Watch for cracks on the arms at heels and mountings.
