The Frank’s International Inner String Spider

The 7 5/8-inch 175-ton Inner String Spider has been engineered to handle strings ranging in size from 2 3/8 inches to 7 5/8 inches. A pneumatic cylinder actuates a link that rotates crankshafts, which, in turn, lift and lower slips. A safety pin can be engaged to disable to the movement of the link, halting the slips in either an “up” or “down” position. This Frank’s International innovation enables remote operation to eliminate the manual bowl and handslips typically required of inner string applications. The slips can also be actuated manually.
