Hydraulic Breaking Unit

Zhuorui break-out units are designed to provide easy, trouble-free assembly and disassembly of drilling tools, BHA and completion equipment.

The unit has the flexibility to be used on equipment; this allows the operator to apply precise torque that can be accurately read on both analog gauges and digital torque recorders. The clamping force is proportional to the diameter and applied evenly, so the clamped part is not damaged, the line is true and the connection is protected.

The unit consists of a standard length bed, independent console and two extension beams on either side, with supporting trolleys and mounted push/pull units. The tailstock is driven by a gearbox/motor with a sprocket/chain arrangement running the length of the bed. A heavy-duty rotator is mounted on the tailstock with the option to transfer the rotator to the headstock.

A separate console allows for more flexible operation. This houses the electric motor, pump, reservoir and other valves. The top panel houses all gauges, control valves, pressure regulators and analog torque gauges.

The Torque Logger allows Tasman to monitor and record torque joints with the help of a touch screen console.
