Function – The TP Products Kelly Spinner is the fastest method for safely making connections. The Kelly Spinner is always in position for use. It bolts to the bottom of the swivel and is out of the way at all times. The driving motor (whether air or hydraulic) has enough torque to make the connection as tight as required. The kelly Spinner can be run off the rig air or hydraulic system (please specify which) or suitable seperate power systems.
Air or Hydraulic Powered – The Kelly Spinner is powered by either a high-speed hydraulic motor or 20 HP multi-vane air motor. These motors enable the Kyll Spinner to start the Kelly spinning at full RPM before the threads are made up. The hydraulic model is controlled by a hand-operated valve, usually placed next to the driller’s console or combined with power tong controls. The free running speed of the hydraulic Kelly Spinner is 78 RPM with 33 GPM at 2,000 psi.
Reversible – The Kelly Spinner is also available with reversible feature for right and left rotation. This feature is available in both hydraulic or air-powered models. Conversion kit available to add reversible feature to standard model 77.
