The kelly spinner is a specialized tool used in drilling operations, driven by either pneumatic or hydraulic motors to rotate the kelly. It works in conjunction with the mousehole pipe clamping device (mousehole tong) to automate the make-up of single joints, enhancing safety, reducing labor, and increasing efficiency. Designed and manufactured according to API Spec 8C “Specification for Drilling and Production Hoisting Equipment,” these kelly spinners offer reliable performance in various drilling environments.
We offer multiple models of kelly spinners in both pneumatic and hydraulic versions, catering to different operational needs.
