It is used to hold the drill rod, oil pipe or casing in workover operations on oil fields.

The pneumatic spider is an automated rotary table-mounted slip system designed for rapid and safe suspension of drill pipe, casing, or tubing during tripping and running operations. Manufactured in compliance with API Spec 7K, this spider utilizes pneumatic actuators to simultaneously engage or retract multiple slip segments, enabling remote operation without manual handling. The unit integrates with rig control systems, allowing the driller to activate the slips from the driller’s cabin, significantly reducing crew exposure on the rig floor. Equipped with interchangeable gripping inserts, the pneumatic spider accommodates various tubular sizes while providing consistent, uniform gripping force.
