Hydraulic Workover Rig(Drawworkless)
The hydraulic drawworkless workover rig is new design for the energy saving.
It is driven hydraulically for drilling, workover and hosting operations. It is unnecessary to use drawwork, wireline, travelling block, hook block and rotary table on the rig.
It is equipped with a hydraulic power end, hydraulic pipe handing tools and other automatic tools which can reduce heavy labor and achieve safety and high efficiency.
Due to the simple design, it is easy to maintain and have a long using life.
This kind of workover rig is suitable for under-balance drilling, slim-hole operation, general workover, snubbing operation, heavy drilling and side tracking etc.
