Prior to purchasing a forklift truck, you must make certain that it is well inspected and given a test run. This applies especially to trucks being obtained on-line. It is very vital to find potential problems with trucks acquired 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 especially 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 part of floor, run the truck around for several minutes while a trained operator tests the hydraulic functions. Then, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking could result in serious problems that will be pricey to fix later on.
The masts and chains must be inspected by a trained person. Check with and without a load that the mast operates well. Watch for 'binding' or sticking of the mast. A warning indication is play in the mast channels or between the fork carriage and mast. Another is creeping forward or creeping down of the mast when loaded. These could be signs 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. Check that the sideshift is not sticking when loaded.
Looking closely at the thickness of the heel for wear or damage should be included in the inspection. The manufacturer of the truck specifies minimum thickness. A loose fit can mean the hanger points or carriage are worn. Watch for cracks on the arms at heels and mountings.
