ISO forks are fixed forks (non-floating) mounted on the machine carriage through 2 attachment points called "hooks".
ISO 2328 normalized forks are certified according the two following main characteristics :
- A mounting class (1,2,3,4 or 5) defining the maximum capacity of the forks. Each of these 5 classes defines the distance between both hooks. Thus, a fork from one class can only be mounted on a similar class carriage.
- A fork type (A or B) defining the distance separating the lower hook from the ground (lower point of the fork's heel).
Note: The attached standard charts represent fork characteristics according to the mounting class (1,2,3,4 or 5) and to the forks type (A or B)
