A forklift should be inspected properly and given a test run prior to buying it. This applies specifically to trucks being acquired on the Internet. It is really vital to detect possible issues with trucks bought from businesses on-line.
Starting the engine from cold is a great idea. Note whether there is too much smoke and the ease with which the engine turns over. This is specifically essential with IC engine trucks.
Testing the performance of the truck in tough situations must be included in the test run. An operator who is qualified can operate the truck in reverse and forward, up the ramp.
You could carry out 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. Then, look at the ground beneath for indications of fluid leakage. Even seemingly minor leaking could indicate serious problems that would be really pricey to fix later on.
A trained individual should inspect the masts and chains. Check with and without a load that the mast works smoothly. Watch for 'binding' or sticking of the mast. A warning indication is play in the mast channels or between the fork carriage and mast. One more is creeping forward or creeping down of the mast when loaded. These could be symptoms of problems with ram, valve or seals.
If the truck is used, the mast may have been changed at some time. Make sure that the mast and any fitted attachments follow the rating plate on a truck. Check that the sideshift is not sticking when loaded.
When inspecting the forks, look closely at the heel thickness for wear or damage. The truck's manufacturer specifies minimum thickness. A loose fit can mean the hanger points or carriage are worn. Look for cracks on the arms at heels and mountings.
