IRON ROUGHNECK

1、The portable iron roughneck with a large working scope is a novel multi-function power tong which can be used to tighten and dismantle connections. It can also replace both the DP power tong for spinning and B type tong for break-out function

2、The compact iron roughneck can be fixed on the substructure and adjusted on the top-and-down positions and the forward-and-backward directions

3、The iron roughneck is controlled hydraulically and it’s torque and speed can be adjusted swiftly in order to realize the foregoing-option maximums on the positive and negative directions. In addition, the top-buckle torques can be controlled exactly with the purpose of DP protection,

4、A split-type structure is adopted and utilized to avoid the bending of DP caused by large torque and the skidding of DP inside the slip

5、The clamping of the up-and-down tongs can be conducted via clamping cylinder and clamping block, the clamping unit also can be automatically re-centered to make the new-and-old DP connections credibly clamped

6、Safety and inspection measures are strengthened under the guidance of the design concept of” Humanism Above All” to meet the requirements of HSE.
