Prior to buying a forklift truck, you must make certain that it is properly inspected and given a test run. This applies particularly to trucks being acquired on line. It is very essential to find possible problems with trucks obtained from companies online.
Starting the engine from cold is a good idea. Note whether there is too much smoke and the ease with which the engine turns over. This is particularly vital with trucks that have IC engines.
Testing the performance of the truck in tough situations should be included in the test run. An operator who is trained could operate the truck in forward and reverse, up the ramp.
You could perform your own inspection of an IC engine truck. On a clear area of floor, run the truck around for a few minutes while a skilled operator tests the hydraulic functions. Afterward, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking can indicate serious issues which will be costly to repair later on.
A trained individual should check the masts and chains. Check with and without a load that the mast operates smoothly. Watch for 'binding' or sticking of the mast. A warning indication is play in the mast channels or between the mast and fork carriage. Another is creeping forward or creeping down of the mast when loaded. These could be symptoms of issues with ram, valve or seals.
The mast may have been changed at some time if the truck is used. 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 damage or wear. The manufacturer of the truck specifies minimum thickness. A loose fit might mean the carriage or hanger points are worn. Look for cracks on the arms at heels and mountings.
