The powerful LB28 offers a maximum torque of 280 kNm and features a rope descent system with a 40tonne retraction force. The machines are said to be stable in operation and can be transported in a single unit. Where transport restrictions apply, the leader features a quick-assembly system to minimise set-up time on-site.
