Liebherr R960 SME

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 different 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.

The 1:14.5 scale model

The crawler excavator is elaborately detailed and the functions of the original are implemented in a new level of sensitivity and performance. Only the best materials are used and the model is available as a finished model as well as a kit.

• Pump with larger delivery volume

Dimensions and weight:

• Length undercarriage: 398 mm
• track width (outside): 265 mm
• Track width of crawler track; 200 mm
• Height of crawler track: 85 mm
• Maximum digging depth: 540 mm
• Height to cab roof: 245 mm
• Width of upper carriage: 206 mm
• Weight of the excavator: 26-27 kg depending on equipment
