摘要：
Crawler dozer and crawler loader having a common design in which the same basic upright frame in the center serves as the implement-linkage mounting structure and, at the same time, forms an integral part of the crawler tractor body. The frame is an Aframe disposed in a transverse vertical plane. It has two double walled legs in the case of the loader and, in either case, has side plates forming those two legs of the frame and clamped at four points on front and rear tractor gage bars by individual, longitudinally and transversely spaced apart, clamping joints.
