Liebherr R960 SME Front Shovel

Liebherr R960 SME Front Shovel

The original

With an optimal blend of productivity and precision, R960 crawler excavators enable you to work in a wide range of excavation or quarry applications. Thanks to their proven hydraulic concept and various operating modes, Liebherr excavators always adapt to your needs. Thanks to the equipment kinematics and the performance of the hydraulic system, R960 crawler excavators develop very high breakout and breakaway forces. The generously designed cylinders guarantee an increase in productivity even in hard material.
