Before buying a forklift truck, you should ensure that it is properly checked and given a test run. This applies particularly to trucks being obtained on line. It is vital to detect potential issues with trucks acquired from businesses 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 crucial with trucks which have IC engines.
Testing the performance of the truck in tough situations must be included in the test run. A skilled operator can drive the truck in reverse and forward, up the ramp.
You could carry out your own inspection of an IC engine truck. On a clear part of floor, run the truck around for several minutes while a trained driver tests the hydraulic functions. Then, examine the ground underneath for signs of fluid leakage. Even seemingly minor leaking can indicate serious issues which will be expensive to repair later on.
The chains and masts should be checked by a trained person. Check with and without a load that the mast works well. Watch for sticking or 'binding' 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 can be symptoms of problems with ram, valve or seals.
The mast might have been changed at some time if the truck is used. 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.
Looking closely at the thickness of the heel for wear or damage must be included in the inspection. The manufacturer of the truck specifies minimum thickness. A loose fit might mean the carriage or hanger points are worn. Watch for cracks on the arms at heels and mountings.
