How do you calculate residual capacity for a forklift truck?

To calculate the residual capacity of a forklift truck, subtract the weight of the load being lifted from the truck's rated capacity. The formula is: Residual Capacity = Rated Capacity - Load Weight. Ensure that the load is evenly distributed and within the forklift's stability limits to maintain safety. Additionally, consider any attachments or accessories that may affect the truck's lifting capability.
