The crawler loader LR 634 Litronic features a comprehensive hydrostatic Liebherr travel drive. Constant power is provided to both tracks which are driven independently. The Litronic system for the LR 634 Litronic allows optimal control of the travel speed and all steering movements. Any required turning radius can be achieved with a simple hand movement, even turning on the spot. The robust Z-bar linkage with cast cross-pipe allows maximum bucket breakout forces and the low sill of the front windshield ensures optimum visibility of the working attachment.
