The tunnel scraper has flexible maneuverability and high work efficiency. The hydraulic system adopts a multi way valve control form and optimizes the ratio to evenly distribute the oil volume, enabling flexible and efficient operation of components such as the bucket, arm, boom, scraper transport groove, etc. The strong and fast working performance enables the tunnel scraper to have high performance during slag removal operations. During on-site rock loading operations, it only takes 0.5-1 minutes to fill 1-3 tons of mining trucks, and only 1.5 minutes to fill 4m ³ side dump mining trucks.
