Carriage classes with their capacity bands and mounting logic — the letter that keeps a fork order from becoming a carriage conversation.
The chart
| Class | Typical capacity band | Common use |
|---|---|---|
| Class I | Up to about 1,000 kg | Light walkies and small electric trucks |
| Class II | About 1,000 to 2,500 kg | The most common electric counterbalance class |
| Class III | About 2,500 to 3,600 kg | Mid counterbalance trucks |
| Class IV | About 3,600 to 5,200 kg | Large electric and diesel counterbalance |
| Class V | Above about 5,200 kg | Heavy diesel and rough-terrain |
How to use it
The class groups carriages and forks by mounting dimensions and capacity band; the truck’s carriage carries its class marking, and the fork order starts from that letter. Bands are approximate industry groupings.
The fork’s own stamped rating at its stated load center governs the lift, and the measurement guide covers the five dimensions that make a fork fit: length, width, thickness, lift-ear spacing and taper.
Capacity checks end at the load chart: the fork class gets the replacement on the truck, the chart decides what it may lift. See the load center and load chart guides for that half of the decision.
Five measurements and one class letter make a fork order arrive right the first time.
