Details

The Bentec gear-driven drawworks were developed to provide the market with more reliable technology and more hoisting performance. Their light weight and small dimensions make them ideal for frequent rig moves or limited offshore crane capacity.
Due to our decades of experience in designing and manufacturing drilling equipment, the Bentec gear-driven drawworks are equipped with modern AC or DC motor technology developed in-house. Bentec also reduces the number of sensors to a useful level. The Bentec gear-driven drawworks need only electrical power and air. No water or hydraulics are necessary, which simplifies the drawworks significantly. Bentec provides many drawworks solutions to meet our customers’ requirements for rigs, whether existing or newly built.
All of these advantages make the Bentec gear-driven drawworks the best choice. A drawworks is just a winch – but equipped with modern and reliable technology, it offers the best performance.
