Spider Elevator
Spider elevator and slips are used for casing running operation. They are used instead of regular slips when the rotary table bushing size is not compatible with the tubular being run. Spider elevators are also used for running flush joint casing pipes because flush joint casings don’t have the collar. The spider elevator grips the body of pipe while running in or pulling out of a hole.
Spider slips & elevators are powered by a heavy duty high-strength coil spring or by air. Driller or another crew member can operate the power slips remotely through a remote panel.
