1.存在问题挖掘机斗杆、铲斗缸液压胶管沿动臂布置,其一端固定在挖掘机上部机架上,另一端固定在动臂上。动臂上的液压胶管应自然弯曲、扭转,并预留一定的伸缩余量。当动臂动作时,机架与动臂连接的液压胶管在动臂牵引下随动臂上扬、下降,前伸、后缩。某小型挖掘机上部机架比较狭小,动臂上的液压胶管排布困难,容易与其它零部件产生碰撞,造成该处液压胶管早期磨损、老化,使其使用寿命大为缩短。液压胶管过度弯曲和扭转,还容易
1. There are problems Excavator arm, bucket cylinder hydraulic hose along the boom layout, one end of the excavator fixed in the upper rack, the other end fixed to the boom. Hydraulic hoses on the boom should naturally bend, twist, and allow for a certain amount of leeway. When the boom moves, the hydraulic hose connected to the boom and the boom is raised, lowered, extended and retracted along with the boom when the boom is pulled. A small excavator upper rack is relatively small, hydraulic arm on the boom arrangement difficult, and other parts collide easily, resulting in the Department of hydraulic hose early wear and tear, the service life greatly reduced. Hose bending and excessive bending is also easy
