| Iron Roughneck |
The iron roughneck is a new multiple functional power tong with a wide holding rang. It can perform the functions of making up and breaking out instead of hydraulic power tong and manual tongs.
Its structure is compact and covers a small working space,and the base is permanently installed to implement the adjustment of the upper and lower and fore-and-aft positions. Its operation scope covers everything from well heads to mouse holes.
Complete hydraulic control or electrical-hydraulic proportional control is used, with adjustable torque and speed performance. The maximum torque and speed that can be opertated in both forward and reverse directions is to get a precise control of the make-up torque and to protect the drill pipe.
The rotary guide rail is installed between the upper and lower tongs to prevent the drill pipe from bending due to large torque so as to avoid the drill pipe from slippage in slips.
