ForkLift Load Rating

It should come as no surprise that a forklift truck is designed to lift a specific weight to a specific height. This is one of the main reasons why there are so many different types and models of forklift trucks. Every forklift truck will have a designated rating plate. This rating plate will display the maximum weight that can be lifted to a specific height and at a given load centre.

All operators should be taught to understand this terminology as part of their training. If it is not understood by your operators, or anyone else in the company, then you should ask your fork lift truck supplier to explain what it all means. It is very important.

Whilst it is safe to lift lesser weights it is not safe to lift greater weights.

When a Forklift Truck attachment is used, even just a side shift, the extra equipment has a weight. In simple terms this extra weight becomes part of the load that the truck is lifting and the maximum actual load must therefore be reduced. Unfortunately the required calculation is not as straightforward as other items, such as the centre of gravity changing which is something that must be considered. The process of reducing the load that can be lifted is called "de-rating".

Only the manufacturer of a fork lift truck can determine the appropriate level of de-rating required. Your fork lift truck supplier should be able to arrange this. Once the level of de-rating is agreed a new rating plate must be attached to the truck, showing the new rating details that apply when the truck is being used with the attachment. If a truck is to be used with more than one attachment then there must be a rating plate to cover each attachment that may be used.
