Description of the Power System
Both the external alternating current and the engine can be used as power source to drive the whole unit. When the engine-driving mode is applied, the engine will power the hydraulic pump and the hydraulic system will control the conveying belt and the sand discharge gates. When external alternating current is applied, the hydraulic pumps will be powered electrically and they will then drive the hydraulic system, but the conveying belt is driven by the electric motor directly.

Description of Sand Tank
The sand tank is made of high-quality carbon steel. The proper internal structure design ensures the sand can flow smoothly. The sand outlet adopts taper design to ensure a smooth sand discharge. The hydraulic gate valve designed at the sand outlet opens or closes the outlet of each compartment flexibly. There is safety passage and manhole on the top. The operators can also lift sand bags to the top and fill the tank from the manhole. There is anti-skid ladder inside the manhole for convenient access.
