Technical Features

1. Adopt low-speed over loading bridge and low-pressure wide base tire, it is easy to move and install, has good cross capacity.
2. Adopt hydraulic flexible drive, the output characteristics can vary automatically along with the outer loading, smooth transmission and low failure rate.
3. Drawworks is driven by gear box, has compact structure and high efficiency.
4. II type mast, hydraulic cylinder rising and telescoping, simple and reliable structure.
5. Drawworks adopt band brake, equipped with hydraulic assist brake. It is characterized by easy and credible operation.
6. Adopt hydraulic redirector, work neatly and expediently, it is easy to move and install.
