钢绳传动的抓铲挖掘机作业时,是利用自重使斗齿进入泥土层或插入物料的。抓取物料过程中,抓铲的提升和松斗钢绳均处于松驰状态。抓铲与臂顶滑轮槽往往不在同一个垂直平面内,提升过程中往往产生斜拉现象,使钢绳从轮槽中跳出来,直接与轮轴摩擦,有可能导致钢绳磨损而断裂,抓铲斗坠落。 Rope-driven grab shovel excavator operation, is the use of self-weight to make the tooth into the soil layer or insert the material. In the process of grasping the materials, the grasping of the shovel and the loose rope of the loose bucket are all in a slack state. Grab shovel and arm top pulley groove are often not in the same vertical plane, the process of climbing often produce oblique phenomenon, so that the rope jump out of the wheel groove, friction directly with the wheel shaft, may lead to wear and tear of steel rope rupture, grab shovel Bucket fall.
