履带式推扒机是履带式推土机的变型产品。它既可推堆,又可扒卸。目前主要用于配合抓斗卸船。通过推扒作业,将舱内边角处物料集中在舱口之下,便于抓斗作业,作业对象多为粒度200mm以下的矿石、煤炭、建筑材料、化肥等做散装物料。我国推扒机的拥有量已达数百台,多数是进口产品。国内已开始研制73.5～117kW的中型推扒机,但尚未形成批量。与
The crawler type pusher is a modified type of crawler type bulldozer. It can push and unload. At present, it is mainly used for unloading with grabs. Through pushing operations, the materials at the corners of the cabin are concentrated under the hatches, which facilitates the grab operation. The objects of the operation are mostly ore, coal, building materials, and chemical fertilizers with a granularity of 200 mm or less as bulk materials. The number of pushers in our country has reached several hundred, and most of them are imported products. China has begun to develop medium-sized pushers of 73.5 to 117 kW, but it has not yet formed batches. versus
