ALF 72D: Pusher leg for BBD 94W rock drill

8321 0201 80

Pusher legs must be light, yet strong. Standard aluminium is light, but it just isn’t tough enough to meet our high demands. Atlas Copco ALF 72 pusher leg is made with an alloy that was developed for use in spacecrafts. Not only is it strong, but it features a large piston diameter for high feed force. A simple, robust design for reliable operation and a minimum maintenance.
