Liebherr LR 636 crawler loader

The LR 636 has an operating weight of 21,200 kg and the maximum bucket capacity is 4.6 cubic metres. Its Tier 4 Final, 4-cylinder Liebherr diesel engine returns 135 kW / 181 hp of power and uses SCR technology.

The new crawler loader features an electronically-regulated drive control system with integrated Eco function. The Eco control system provides more economy for the drive unit in light to medium–heavy operations compared with the previous generation machine.

The proactive power control is another innovation of this 6th generation machine. Here, both internal engine and external machine parameters are recorded – such as the actual deflection of the drive joystick. This results not only in faster reaction times, but also tangibly higher performance and pulling power for driving and loading modes.

In order to translate the engine performance most effectively into working output, the optimal weight distribution and the long chassis combine to offer a particularly high tipping load, which in turn increases the load capacity.

The compact components of the hydrostatic travel drive facilitate a particularly low centre of gravity. The low engine oil sump of the Liebherr diesel engine means that it is suitable for angled positions of up to 45 degrees. This enables Liebherr crawler loaders to negotiate steep slopes safely and efficiently.

The chassis units have pendulum mountings and flexible bearings. As a result, unevenness in the ground is balanced out and particularly good contact with the ground is achieved which, in turn, improves climbing ability and firm footing on uneven terrain. By rearranging the support rollers, it was possible to further improve the self-cleaning effect of the chassis.
