The suspension mechanism is installed above the left and right front wheels and connected with the wheels through the steering arm assembly.
The rocker arm and rocker are installed on the frame, and the rocker is rotatably connected to the frame; The cable mounting block is fixed on the rocker; The side discharge cable is connected to the cable mounting block; The side discharge cable is guided by the cable roller and then connected with the side discharge slider; The side unloading slide block is sleeved on the roll lock guide post; The guide post mounting plate and the coil lock spring are installed on the coil lock guide post.
One side of the rollover slider is also connected with a rollover stop, and when the rollover slider is pulled by the rollover cable, the end of the rollover stop is clamped with the suspension mechanism.
