Main frame of motor grader DZ-98B

The main frame of the motor grader is of welded construction, comprising a head, main pipe and rear portion. The head mounts a front axle, and additional working equipment. Suspension mechanism of different working equipment has the same design besides the design of scarifier suspension.
Therefore the frame head of motor grader with scarifier is different from the frame head of other comp-lete sets of motor grader. The head also receives the traction frame ball support. The brackets of the front axle drive shafts are welded to the frame main pipe. The inside space of the pipe serves as an air heeiver of the pneumatic system.

The frame rear portion consists of two box-section side members.In the front portion a transverse pipe of the frame is welded to the side members, its inside space serving as a tank of the motor grader hydraulic system. A filter is mounted at one end of the tank and an oil dipstick and a filler neck at the other end. Second receiver (minor) is arranged in the I.h. side member.
Hoisting hooks welded to the frame front and rear portions serve (with obligatory application of a distance frame) for loading and unloading of the motor grader (on the flat-cars, vessels, etc.).
