Before buying a forklift truck, you must ensure that it is well checked and given a test run. This applies specifically to trucks being bought on-line. It is important to detect potential issues with trucks purchased from companies 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 vital with trucks which have IC engines.
The test run must include an inspection of the truck's performance in tough situations. An operator who is trained could drive the truck in forward and reverse, up the ramp.
You could carry out your own inspection of an IC engine truck. On a clear part of floor, run the truck around for a few minutes while a skilled operator tests the hydraulic functions. After that, examine the ground underneath for indications of fluid leakage. Even seemingly minor leaking could result in serious issues that will be pricey to fix later on.
The chains and masts must be checked by a qualified individual. Check with and without a load that the mast operates smoothly. Watch for 'binding' or sticking of the mast. A warning sign is play in the mast channels or between the fork carriage and mast. Another is creeping forward or creeping down of the mast when loaded. These can be symptoms of problems with ram, valve or seals.
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. Check 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 might mean the hanger points or carriage are worn. Watch for cracks on the arms at heels and mountings.
