Description
The Original

Technology in the service of performance - When designing the systems in Liebherr's own development departments, the combined technical know-how of the individual divisions results in coherent and optimized systems. The Liebherr electronics, the Positive Control hydraulic system or even the motors are designed from the ground up for flawless interaction and maximum work performance with fast and fluid movements.

Positive Control Hydraulic System - Two working pumps for maximum excavation and travel performance, plus a dedicated pump in the circuit for rotary motion, provide the necessary power to the affected consumers. The Positive Control system optimizes the combined movements for the different operations to be performed, be it grading, digging / loading or even lifting, each with or without travel.

Particularly fast work cycles - With its generously dimensioned transmission elements, the R 946 enables fast work cycles. For example, the swing drive of the upper carriage can quickly reach its maximum speed with a high swing torque.

Operating pressure - The pressure level of the hydraulics makes it possible to achieve the maximum tearing and penetration forces without temporary overpressure. The maximum forces are thus guaranteed in continuous operation throughout the working phase, creating excellent production conditions.
