1.  Closed loop hydraulic system and constant hydraulic oil temperature controller are used. Key hydraulic accessories include: hydraulic plunger pump, adjuster mechanism with servo, hydraulic motor and reducer are all made by internationally known brands and offer stable and reliable and reliable performances.
2.  Pneumatic Water Supple System. The pressure is provided by the air tank on the chassis with pressure protection devices .The Water inlet connector fits for both normal water pipe and fire fitting.
3.  Multi-outlet washing design. Cleaning requirements are met by the three fixed pipes for washing the agitator drum ,charging hopper and discharging hopper respectively ,and another flexible water outlet.
4.  Three-point Operation System. One in the cab to allow control of the agitator drum to turn forward and reverse, and to perform the "feed" ,"discharge", "agitate" and "stop" functions .Two at the rear with one operation handle at each side to perform "charge" "accelerate" ,"discharge" ,"agitate" and "stop" .Three are interlocking.
