The BASIS OF RATING for a conventional 2.5T forklift is simple, and something that forklifts operators should have a basic understanding of. The basis of rated and alternative capacities of a truck shall be the strength of its various components and stability in accordance with the requirements at the time of manufacture.
Where operating conditions differ from normal (e.g. different attachment, abnormal movement, inclined or rough surfaces, position or attitude of the truck or part of the truck when required to handle a load), it may be necessary to use either a truck with a greater rated capacity or a specially designed truck as appropriate to the special conditions.
All forklift capacities must be given by the manufacturer of the Forklift, and different things can added to or changed on the forklift can drastically change the RATED Capacity.
If you are unsure of what your rated capacity is of your forklift, just check the rating plate that is fitted to the forklift. If the rating plate is not visible, contact the manufacturer of the forklift and ask for a rating plate (you will pay a fee for this). They will ask you for the specifications of the forklift calculate the rated capacity and give you a stamped rating plate.
