Prior to purchasing a forklift truck, you should ensure that it is correctly checked and given a test run. This applies especially to trucks being bought on-line. It is important to detect potential issues with trucks obtained from businesses on the Web.
Be sure to start the engine from cold, and note the ease with which the engine turns over and whether there is too much smoke. This is especially crucial with trucks that have IC engines.
Testing the performance of the truck in challenging situations must be included in the test run. A skilled driver can maneuver 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 qualified driver tests the hydraulic functions. After that, look at the ground beneath for indications of fluid leakage. Even seemingly insignificant leaking can result in serious problems that would be very pricey to repair later on.
A trained person should 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 ram, valve or seals.
If the truck is used, the mast might have been changed at some time. Make certain that the mast and any fitted attachments adhere to 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 manufacturer of the truck specifies minimum thickness. A loose fit could mean the carriage or hanger points are worn. Watch for cracks on the arms at heels and mountings.
