Before purchasing a forklift truck, you should ensure that it is properly checked and given a test run. This applies specifically to trucks being bought on the Web. It is vital to detect possible problems with trucks acquired from companies on the Internet.
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 IC engine trucks.
Testing the performance of the truck in challenging situations should be included in the test run. A trained operator can maneuver the truck in reverse and forward, 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 driver tests the hydraulic functions. After that, look at the ground underneath for signs of fluid leakage. Even seemingly insignificant leaking could result in serious issues that would be very expensive to fix later on.
A trained person should inspect the chains and masts. Check with and without a load that the mast operates well. Watch for sticking or 'binding' of the mast. A warning indication 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 can be signs of problems with seals, ram or valve.
The mast might have been changed at some time if the truck is not new. 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.
When checking the forks, look closely at the heel thickness for wear or damage. The truck's manufacturer specifies minimum thickness. A loose fit can mean the hanger points or carriage are worn. Watch for cracks on the arms at mountings and heels.
