4.2.1 Full hydraulic steering gear
The full hydraulic steering gear is referred to as the cycloidal full hydraulic steering gear, which is composed of
a common steering gear and a combination valve. The hole on the cap of the combination valve serves as the
system safety valve. In addition, there is a two-way overload valve inside the valve body. It will produce the
high within the hydraulic system when the forklift wheels are subject to accidental shocks during the running.
When being under pressure, it plays the role of protection to prevent the damage on parts. The safety valve and
two-way overload valve were adjusted in plant. Users do absolutely not make adjustment. (Fig. 4-3)
