A forklift must be inspected well and given a test run prior to buying it. This applies specifically to trucks being acquired on the World Wide Web. It is really essential to find potential problems with trucks bought 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 particularly vital with IC engine trucks.
Testing the performance of the truck in tough situations should be included in the test run. A trained driver can maneuver the truck in forward and reverse, up the ramp.
You can check an IC engine truck yourself. On a clear part of floor, run the truck around for several minutes while a trained operator tests the hydraulic functions. Afterward, look at the ground beneath for indications of fluid leakage. Even seemingly minor leaking could indicate serious problems which will be expensive to fix later on.
A skilled individual must inspect the chains and masts. 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 fork carriage and mast. One more is creeping forward or creeping down of the mast when loaded. These can be signs of problems with ram, valve or seals.
The mast may have been changed at some time if the truck is not new. 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 truck's manufacturer specifies minimum thickness. A loose fit could mean the hanger points or carriage are worn. Look for cracks on the arms at mountings and heels.
