Product Description

Drawworks is an important part of a drilling rig. Drawworks come in many varieties and can include AC, DC or mechanical operations. The steel cable (drilling line) used in draworks can be used to hoist and lower hundreds of thousands of pounds of weight, including lifting steel pipes out of boreholes. Drawworks also come in a variety of power ratings that can range from 1000 HP to 3000 HP and above.
