YM Series

The YM series hydraulic cathead is a kind of oilfield equipment used at offshore and land rigs. This hydraulic catwalk can be matched with rig tong to perform makeup and breakout for tubulars including drill pipe, drill collar and casing pipe. Output torque is adjustable, and thereby operation is precise, stable and continuous.

Our hydraulic cathead can be coupled with spinning wrench to completely realize mechanical operation. Hence, it reduces labor intensity, improves working efficiency, ensures worker safety, and saves cost.

Currently, this makeup cathead is provided in 4 types for your options, containing 5t, 8t, 10t and 16t types. Please see the following table for parameters of our hydraulic cathead.
