API 7K Safe and Durable Equipment Iron Roughneck for Drilling Needs
Description:
- The portable iron roughman 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.
The compact iron roughman can be fixed on the substructure and adjusted on the top-and-down positions and the forward –and –backward directions.
The iron roughman 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.
A split-type structure is adopted utilized so as to avoid the bending of DP caused by large torque and the skidding of DP inside the slip.
The clamping of the up-and- down tongs can be conducted via clamping cylinder and clamping block, which the clamping unit also can be automatically re-centered to make the new –and- old DP connections credibly clamped.
Safety and inspection measures are strengthened under the guidance of the design concept of “Humanism Above All”to meet the requirements of HSE.
