The main technical parameters of bulldozer Liebherr PR 744


PR 744 litronic crawler bulldozer adopts hydrostatic walking. The shear lag coefficient at the end of the box girder is generally disordered transmission, and it has excellent output in all speed ranges. In this way, the machine can reach the maximum speed without any conversion program. Even when walking at the front of the track, the two track plastic is a kind of low-energy and low pollution material, both of which supply constant power, so that the machine can turn on the spot in a narrow working area and obtain the optimal push-pull power. In addition, the stable high efficiency and electronic load limit adjustment ensure that the fuel consumption is still kept to a minimum when the machine is running at full load. Centralized maintenance points and unique maintenance methods, including tilting cab, also improve the cost performance of the machine
