东方红60型推土机,是在东方红75型拖拉机的基础上加装推土装置而成。目前已在林区的筑路、基建等工程中广泛采用。其车架主要是由前梁、左右纵梁、后托架和前后横梁所组成的薄壁杆空间构架,各构件之间用铆钉连接。车架是安装和支撑拖拉机各部件或总成的基础。在拖拉机工作中,它除了承受这些部件的重量及其承受的动载荷外,还承受着相当大的履带工作张力,除地而作用于履带的阻力外,还要受到拉、压、弯、扭 The Dongfanghong 60 bulldozer is a bulldozer installed on the Dongfanghong 75 tractor. It has been widely used in road construction and infrastructure projects in forest areas. Its frame is mainly composed of a thin-walled rod space frame composed of a front beam, a left and right longitudinal beam, a rear bracket and a front and a back beam, and each member is connected with a rivet. The frame is the basis for mounting and supporting the components or assemblies of the tractor. In the work of tractors, in addition to the weight of these components and the dynamic loads they are subjected to, they also bear considerable track work tension. In addition to the resistance of the tracks, they are also subjected to pulling, pressing, bending and twisting.
