3.1.2 Oil can for steering
The oil can for steering (Fig. 3-2) serves as a common fuel tank for steering and braking,
and integrates an oil gauge, a breather and a return oil filter.

3.1.3 Duplex pump
The steering pump and brake pump are combined to form a duplex pump, which is
driven by a single motor. The duplex pump sucks oil from the crude oil pipe and the front
pump supplies the steering gear. The pressure oil from the back pump enters the driving axle
through the brake valve to meet the requirements of dynamic braking. The oil from the
duplex pump returns to the oil can through the internal filter when the operations are in
neutral condition. The principle of the hydraulic steering system is shown in Figure 3-3.
