OREANDA-NEWS. April 05, 2012. The Tugnui open-pit mine obtained a new Liebherr PR 734 XL Litronic bulldozer. The machine came through the equipment upgrade program. A remarkable feature of this bulldozer model is availability of a separate hydrostatic drive per each track.

The Liebherr PR 734 Litronic bulldozer's hydrostatic drive provides high power in all speed ranges. The machine is able to achieve maximum speed without any gear shifting. The two permanently driven tracks provide force closure operation even when travelling along a curved course, enabling the vehicle to spin turn in a very confined area and delivers optimum traction force. Constant high performance and limit load electronic control ensure minimum fuel consumption even when operating under limit loads.
