A forklift must be inspected properly and given a test run before purchasing it. This applies particularly to trucks being obtained on the Web. It is very vital to find potential issues with trucks obtained from companies on the Web.
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 specifically essential with trucks which have IC engines.
The test run must include a check of the truck's performance in tough situations. A driver who is trained could drive the truck in reverse and forward, up the ramp.
You can 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 trained operator tests the hydraulic functions. After that, examine the ground beneath for signs of fluid leakage. Even seemingly minor leaking could result in serious issues that will be really expensive to fix later on.
The chains and masts should be inspected by a qualified individual. Check with and without a load that the mast works well. Watch for 'binding' or sticking of the mast. A warning sign is play in the mast channels or between the mast and fork carriage. Another is creeping down or creeping forward of the mast when loaded. These could be signs of issues with valve, seals or ram.
The mast may have been changed at some time if the truck is used. 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 wear or damage should be included in the inspection. The truck's manufacturer specifies minimum thickness. A loose fit could mean the hanger points or carriage are worn. Watch for cracks on the arms at heels and mountings.
