The correct capacity is the rating for the actual truck, load centre, lift height and attachment configuration. A headline lifting capacity does not mean the truck can lift that weight in every position. Use the machine’s applicable data plate and manufacturer information.
Describe the complete load
Record the maximum weight including pallet or container, length, width, height and how the weight is distributed. Long, off-centre or irregular loads need particular attention. If the centre of gravity is uncertain, ask a competent person to establish the information needed for equipment selection.
Understand the load centre
The load centre describes the relationship between the supported load and the fork face. Moving a load farther away changes the forces on the truck. A rating at one load centre cannot simply be applied to a different load without checking the applicable capacity information.
Add the actual height and attachment
Tell the supplier the highest placement height and every attachment you intend to use. Side shifts, clamps and other attachments can change the effective load centre and capacity. Request the rating for the complete combination rather than relying on separate marketing specifications.
Check the data plate and documents
Before purchase, ask for legible capacity information that matches the truck, mast and fitted attachment. The maximum advertised lift height may not carry the maximum nominal load. Resolve any missing or inconsistent documentation with the manufacturer or competent supplier.
Use the brief to support a qualified decision
This guide helps you describe the job. It does not calculate a safe load or replace the manufacturer’s limits, workplace procedures or operator training. Do not add counterweight, modify the equipment or assume a load is safe because it can be lifted.
