Cab of motor grader DZ-98B
The motor grader is outfitted with an all-metal cab with all-round glazing. The inner walls of the cab are lined with decorative lining, which is easily cleaned. Spaces between the outer shell and inside linig are packed with heat-insulating material. All the joints of the cab are sealed with special rubber packings.The cab flor is covered with a rubber-felt mat serving both for heat-insulating and for reducing the noise and vibration on the working site. Vibration is also reduced due to fastening of the cab platform to the frame with the use of rubber shock absorbers. In case of transportation by railway with the limited outlines the cab may be removed from motor grader. The cab doors are provided with the locks.
Special spring-loaded latches 5 fixed on the cab side walls secure the doors in the opened position. Seat 13 is adjustable to suit the height and mass of the driver.

The cab roof mounts two flashing beacons 10 and four headlamps for illuminating the working site. These lighting means and the heater are switched on from switch board 3. The heating and ventilation system is the heater 1, comprising a heat exchanger and electric air blower, air ducts 2,4. Engine cooling system fluid circulates via the heat exchanger. Intake holes of air duct 4 via which air from atmosphere is fed to the heat exchanger are made on the cab I.h. wall. From the heat exchanger the warmed up air via air duct 2 is forced into the cab.
The point of air intake can be changed, using the air duct flap controlled by handle 6. When the latter is shifted towards the seat, air intake from the cab is performed, when it is the opposite position, air is delivered from the cab and additionally from the atmosphere.
In the warm season the heater cock positioned above the engine placed near to the engine tray from the right in direction of motor grader travel for YAMZ-238HD3 and YAMZ-238HD2 engines should be shut off and the fan may be used for cab ventilation.
