Abstract

A compact spinner assembly for rotating tubulars, such as pipes or casings, particularly in drilling operations, is provided. The compact spinner assembly includes a first arm and a second arm, each having a drive roller and the ability to pivot to retain and rotate a tubular. The assembly includes hydraulic actuators for adjusting the arms between open and closed positions, allowing for secure engagement with tubulars of varying diameters without manual adjustment. A motor operably connected via a power transmission system with chains, sprockets, and gears rotates the drive rollers in both clockwise and counterclockwise directions, enabling efficient and continuous rotation of the tubular. The compact design allows for mounting the assembly within confined spaces such as drilling masts, enhancing worker safety and increasing productivity by facilitating hands-free operation and reducing the need for manual handling.
