Before buying a forklift truck, you must make sure that it is correctly inspected and given a test run. This applies particularly to trucks being purchased online. It is very vital to detect possible problems with trucks obtained from businesses online.
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 essential with trucks which have IC engines.
Testing the performance of the truck in challenging situations must be included in the test run. A skilled operator could operate the truck in forward and reverse, up the ramp.
You could inspect 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. Then, look at the ground beneath for signs of fluid leakage. Even seemingly insignificant leaking can result in serious issues that would be costly to fix later on.
A qualified 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 could be symptoms of problems with valve, seals or ram.
The mast may have been changed at some time if the truck is not new. Make certain that the mast and any fitted attachments adhere to the rating plate on a truck. Make sure that the sideshift is not sticking when loaded.
When checking the forks, look closely at the heel thickness for damage or wear. The manufacturer of the truck specifies minimum thickness. A loose fit might mean the hanger points or carriage are worn. Watch for cracks on the arms at mountings and heels.
