Sprinkler power take-off device is a set of speed change gears, also known as power output device, which is generally composed of a gear box and a clutch. It is connected with the transmission using a gear and is connected with the lift pump shaft. It is a separate gearbox. The stalls, on this file, a throttle, lift pump can run. The lift pump is a hydraulic device that lifts the car box and implements the dump function. Special vehicles that require extra power, such as dump trucks, fire engines, cement mixers, and refrigeration, are obtained through a power take-off device. The power take-off device is an additional device mounted on the outside of the water sprinkling gearbox (the power take-off of the cement mixer is On the clutch housing, it takes power from a gear in the gearbox. The turning on or off of this power is controlled by a solenoid cut in the cab. The power take-off device drives the high-pressure oil pump for the dump truck, drives the water pump for the fire engine, drives the compressor for the refrigerating vehicle, and drives the hydraulic motor to rotate the stirring tank.
Sprinkler power take-off is generally connected to the drive shaft or directly connected to the gear pump. In China, it is generally connected to the drive shaft. Few people design the direct connection with the gear pump. In Europe and North America, due to the multiple design of the power take-off device, there are many kinds of . Power take-off manufacturers (eg Hydrocar of Italy, PZB, Muncie, USA, etc.) have designed different interfaces at the output of the power take-off of the sprinkler to meet the requirements of different types of interfaces. The commonly used output interfaces are: DIN 5462, SAE "B" 2 & 4, SAE "C" 2 & 4, etc. The output flanges are generally DIN20, DIN10, SP1300, SP1400, etc. In Europe, the DIN 5462 interface is very common, and gear pump manufacturers will design according to this interface. In order to perfectly connect with the power take-off, the intermediate drive shaft is saved and space is reduced.
Most domestic power take-offs are used on sprinklers, so the requirements for power take-offs are relatively single. In Europe and North America, due to the high demand for power take-offs of special vehicles, power take-off manufacturers will design multi-output power take-offs or power take-offs with clutches. The power take-off control methods are also varied. They are: Mechanical control, hydraulic control, pneumatic control, vacuum source control, electronic control, etc., where the air control is more common.

In recent years, due to the rapid development of the Chinese water truck market, some international professional power take-off makers, such as Interpap, Italy, also landed in China. With the development of time, China’s power take-off devices will become increasingly diverse and specialized.
