Description
A pneumatic spider provides a reliable, automated solution for gripping and supporting tubular strings, significantly reducing manual handling risks while improving operational efficiency.
Designed for modern oilfield applications, our pneumatic spiders deliver consistent slip engagement, high load capacity, and compatibility with standard API tubular sizes.
RIGRS pneumatic spiders are air-operated handling tools used to hold and support casing or tubing during running and wellsite handling operations. They help improve safety and efficiency by reducing manual effort during make-up/break-out and pipe positioning on the rig floor.
Our pneumatic spiders can be configured with replaceable slips and size ranges to match your casing/tubing program. Optional safety features and documentation can be supplied for project requirements. For correct sizing, confirm pipe type (casing/tubing), OD range, required load, and available air supply conditions.
What Is a Pneumatic Spider？
A pneumatic spider is a wellhead handling tool used to hold and suspend tubulars such as casing, tubing, and drill pipe during drilling and workover operations.
It uses compressed air to automatically control slip opening and closing, ensuring stable gripping force and minimizing manual intervention.
Pneumatic spiders are widely used in oilfield drilling rigs, workover rigs, and well servicing operations where safety and efficiency are critical.
