A forklift should be inspected correctly and given a test run before buying it. This applies especially to trucks being acquired on the World Wide Web. It is essential to detect possible issues with trucks obtained from businesses 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 especially crucial with trucks which have IC engines.
Testing the performance of the truck in challenging situations should be included in the test run. A qualified operator could maneuver the truck in reverse and forward, up the ramp.
You can 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 driver tests the hydraulic functions. Then, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking could indicate serious problems that will be very expensive to fix later on.
The masts and chains must be checked by a trained individual. Check with and without a load that the mast operates smoothly. 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 down or creeping forward of the mast when loaded. These can be symptoms of problems with seals, ram or valve.
The mast may have been changed at some time if the truck is used. 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 wear or damage must be included in the inspection. The manufacturer of the truck specifies minimum thickness. A loose fit can mean the carriage or hanger points are worn. Watch for cracks on the arms at heels and mountings.
