英国 Broyt 公司制造的 Swamp-ROC 型液压挖掘机上取消了行走传动机构。它利用动臂和斗杆来移动。向前进时,伸出动臂,将斗插入土中,然后收缩臂,将机器拉向前。动臂长6.9米,每次伸缩可使机器移动6米。转弯时,利用动臂使一对轮离地,然后使机器向所需要的方面回传。将斗顶到地面可将机器的任一端抬起1.65米,可以爬过障障或者跨过1.5米宽的沟。长距离移动时,将它的斗固定在一台卡车底上,将前部钢轮撑离地面,用后部橡胶轮胎在公路上拖着走。该机器自重略超过10吨,可以爬45°的陡坡,并可在25°的斜坡上作业。在它的轴上用螺钉安装圆形助浮板,可将对地压力
The drive transmission mechanism was cancelled on a Swamp-ROC hydraulic excavator manufactured by Broyt in the United Kingdom. It uses booms and sticks to move. As you advance, extend the boom, insert the bucket into the soil, then retract the arm and pull the machine forward. The boom is 6.9 meters long and each machine can move 6 meters. When turning, use the boom to make the wheels off the ground and then return the machine to the required area. Raising the bucket to the ground lifts 1.65 meters from either end of the machine, allowing it to climb over obstacles or across a 1.5 meter wide ditch. As it moves long distances, its bucket is fixed on the bottom of a truck, the front steel wheel is pulled off the ground, and the rear rubber tires are dragged on the road. The machine weighs slightly more than 10 tons and can climb a steep slope of 45° and can work on a slope of 25°. Installs a circular assist plate with screws on its shaft to apply pressure to ground
