Introduction of ZM30 Road Repair Small Mini Digger Machines Crawler Micro Hook Excavator 

Dynamical system：

1.  The domestic well-known brand of Changchai/Science engine can ensure the reliability of the machine under severe working conditions.

2. Equipped with high temperature resistant elastic coupling, which has the effect of shock isolation. With dynamic compensation function to protect the engine and main pump. Other manufacturers mostly use mechanical connections.

Oil supply system 

1.Two-stage air filter for easy cleaning.

3.The hydraulic oil tank breathing valve is equipped with pressure compensation valve and air filtering function. The machines of other manufacturers are only covers and do not have these functions; the standard aluminum fuel tank completely solves the rust problem of the iron fuel tank and ensures the clean fuel. Other manufacturers mostly use iron fuel tanks or the fuel tanks that come with the engine. The fuel tanks that come with the engine are affected by engine vibration and the fuel tanks are easily damaged.

The hydraulic oil tank is equipped with magnets as standard to prevent small items such as rust from entering the hydraulic system

Cooling system

1. Built-in exhaust fan and good heat dissipation system to ensure that the machine does not heat up and prolong its service life

2.The external air circulation system of the engine ensures the heat dissipation of the engine and reduces the intake temperature of the engine, making the engine more powerful and longer life.
