A forklift must be checked correctly and given a test run prior to purchasing it. This applies specifically to trucks being bought on the World Wide Web. 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 excessive smoke and the ease with which the engine turns over. This is specifically crucial with IC engine trucks.
The test run should include an inspection of the truck's performance in challenging situations. A driver who is qualified could drive the truck in forward and reverse, up the ramp.
You could perform 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. Then, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking can indicate serious problems which will be expensive to fix later on.
A qualified individual should check the masts and chains. Check with and without a load that the mast operates well. Watch for sticking or 'binding' 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 can be symptoms of problems with ram, valve or seals.
The mast might have been changed at some time if the truck is used. Make certain 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 wear or damage must be included in the inspection. The manufacturer of the truck specifies minimum thickness. A loose fit might mean the hanger points or carriage are worn. Look for cracks on the arms at heels and mountings.
