A forklift must be inspected properly and given a test run before purchasing it. This applies specifically to trucks being acquired online. It is very important to detect potential issues with trucks bought from businesses on line.
Be certain to start the engine from cold, and note the ease with which the engine turns over and whether there is excessive smoke. This is especially crucial with trucks which have IC engines.
The test run should include a check of the truck's performance in challenging situations. A driver who is qualified can 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 several minutes while a trained operator tests the hydraulic functions. After that, look at the ground beneath for signs of fluid leakage. Even seemingly insignificant leaking can result in serious issues that will be very pricey to repair later on.
A trained individual must check the masts and chains. Check with and without a load that the mast operates 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. One more is creeping forward or creeping down of the mast when loaded. These can be symptoms of problems with seals, ram or valve.
If the truck is used, the mast may have been changed at some time. Make sure that the mast and any fitted attachments adhere to the rating plate on a truck. Make certain that the sideshift is not sticking when loaded.
When checking the forks, look closely at the heel thickness for wear or damage. 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.
