JC series Drawworks are modular designed, lightweight, small-dimensioned, quiet and easy to maintain. Suitable for onshore or offshore drilling operations.



The JC series 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. The JC series drawworks could equipped with modern AC or DC motor. To make the system more easier for maintenance, we also reduces the number of sensors to a useful level. All of these advantages make the JC series drawworks the best choice. A drawworks is just a winch – but equipped with modern and reliable control system, it offers the best performance.
