Which forklifts does this fork positioner fit?

Forklifts with an ISO class 2A carriage and a spare auxiliary hydraulic function, typically trucks in the 1.5 to 2.5 tonne range.

How much can it handle?

It is rated at 2,500 kg, subject to the residual capacity of your forklift with the positioner fitted.

It moves the forks apart or together hydraulically, so the operator can adjust spacing for each pallet without leaving the seat.
