The Alf 72-pusher legs are double-acting, they push out and pull back in.
When time is short, simple connection means money saved.
The feed control is placed on the pusher leg, which makes it easy to reach.
These pusher legs were made with an aluminium alloy that was first developed for use in spacecrafts. They’re strong and feature a large piston diameter for high feed force. The simple and robust design makes operations reliable and promise minimum maintenance time.
