JAC HEAVY DUTY TRUCK
1. Agitating tank
Agitating tank body is the main part of the concrete transportation truck, it consists the tank body, guide tank, vane and
assistant vane. The funneled guide tank assures the feeding properly, the curve vane helps to output performance of
lower landslide level concrete, there are holes on the vane, which reduces the adhering of the concrete. The assistant
vane with the agitating ability helps to improve the pre-agitating concrete quality. The whole agitating tank is mounted
above the bracket; there are two supporting rollers in the rear. The checking hole on the agitating tank is for easy repair.
2. Transmission system
The transmission system gets the power from the original engine, namely the power is output after get through the en鄄
gine and chassis, and then power is transmitted to the variable volume plunger hydraulic pump through the universal
joint. The fixed volume plunger motor is driven by high pressure oil of the hydraulic motor, then the hydraulic motor for鄄
wards the power to the reducer and drives the tank in clockwise or counterclockwise, then feeding, agitating or output is
realized. The output flange of the reducer can be turned within±6?, which compensates the axial movement of agitating
tank and assures the drive of agitating tank is not affected by the distortion during the driving.
3. Hydraulic system
Hydraulic system is open type, it main consists hydraulic pump, reducer, high pressure pipe, low pressure pipe and oil
return pipe etc. There is manual servo adjustment handle on the hydraulic pump, the hydraulic oil flow and direction can
be adjusted, which controls the turning and revolution speed of agitating tank. The clockwise and counterclockwise ro鄄
tary of the agitating tank is able to get stepless speed adjustment.

4. Control system
The rod type control mechanism is arranged in three locations, one in driving
cab, the other two in the rear, it incorporates the soft shaft control in the driv鄄
ing cab, it's for locking the direction of agitating tank to assure the agitating of
the agitating tank during driving; the two sides in the rear are connection rod
control system, turn the handle, and it drives the adjustment handle of the hy鄄
draulic pump and the engine accelerator pedal to adjust the volume and di鄄
rection of the hydraulic oil, then the feeding and output of the agitating tank is
under control; the soft shaft control is on the left of the driving cab, it's simple
and flexible and easy to operate.
