Abstract
A low profile, high torque spider assembly for use on a rotary table of a drilling rig to secure a vertical pipe string such as a drill string is disclosed. The spider is comprised of a plurality of slips to engage with the drill string, a horizontal actuator, and a means for transferring the horizontal motion of the horizontal actuator to the vertical slips. Because of the horizontal orientation of the actuator means, this spider has a low deck profile and occupies less deck space, thereby making it particularly suitable for drilling rigs with small rotary table openings.
