Before buying a forklift truck, you should ensure that it is well checked and given a test run. This applies particularly to trucks being purchased on line. It is very important to find 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 especially essential with IC engine trucks.
The test run should include a check of the truck's performance in challenging situations. A driver who is trained can drive the truck in forward and reverse, up the ramp.
You could inspect an IC engine truck yourself. On a clear area of floor, run the truck around for several minutes while a skilled driver tests the hydraulic functions. Then, examine the ground beneath for signs of fluid leakage. Even seemingly insignificant leaking could result in serious problems that will be really pricey to fix later on.
The chains and masts must be checked by a trained person. Check with and without a load that the mast works well. Watch for sticking or 'binding' 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 valve, seals or ram.
If the truck is used, the mast might have been changed at some time. 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 hanger points or carriage are worn. Watch for cracks on the arms at mountings and heels.
