The main valve and the triple series pump are imported parts. The main shaft rotation adopts the closed circuit driven by double motor, which has high working efficiency and large torque. The power head is fed in by the cylinder chain double speed mechanism or the cylinder straight push structure. The power head leaves the orifice and is divided into translation or flipped structure; the crawler walks on its own; the mast cylinder is up and down, foldable, convenient for transportation and storage, and has the function of touching the ground; The hydraulic system adopts load sensitive control, and the upper and orifice worktables are installed, and the upper and lower straightening devices are provided, and the orifice is equipped with hydraulic retainers. Overall structure: divided into crawler self-propelled, tire type, platform type.
