A forklift must be checked correctly and given a test run prior to buying it. This applies specifically to trucks being obtained online. It is vital to detect potential issues with trucks bought from companies 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 particularly crucial with trucks which have IC engines.
Testing the performance of the truck in challenging situations must be included in the test run. A qualified driver can maneuver the truck in reverse and forward, up the ramp.
You can perform your own inspection of an IC engine truck. On a clear area of floor, run the truck around for several minutes while a skilled driver tests the hydraulic functions. Afterward, examine the ground underneath for indications of fluid leakage. Even seemingly insignificant leaking could indicate serious problems that will be very costly to repair later on.
A qualified person must check the masts and chains. 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 mast and fork carriage. One more is creeping down or creeping forward of the mast when loaded. These could be signs of problems with seals, ram or valve.
The mast might have been changed at some time if the truck is not new. Make sure that the mast and any fitted attachments follow 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 must be included in the inspection. The manufacturer of the truck specifies minimum thickness. A loose fit could mean the carriage or hanger points are worn. Watch for cracks on the arms at heels and mountings.
