Prior to purchasing a forklift truck, you must make certain that it is correctly checked and given a test run. This applies specifically to trucks being acquired on-line. It is vital to detect possible issues with trucks acquired from companies online.
Starting the engine from cold is a good idea. Note whether there is excessive smoke and the ease with which the engine turns over. This is specifically crucial with trucks which have IC engines.
The test run should include an inspection of the truck's performance in tough situations. A qualified operator can operate the truck in reverse and forward, 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 skilled operator tests the hydraulic functions. Then, look at the ground beneath for indications of fluid leakage. Even seemingly minor leaking can lead to serious problems which would be expensive to repair later on.
A trained person must check the masts and chains. Check with and without a load that the mast works 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. Another is creeping forward or creeping down of the mast when loaded. These can be signs of issues with valve, seals or ram.
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. Make certain that the sideshift is not sticking when loaded.
Looking closely at the thickness of the heel for damage or wear should be included in the inspection. The manufacturer of the truck specifies minimum thickness. A loose fit could mean the hanger points or carriage are worn. Look for cracks on the arms at heels and mountings.
