Abstract
A skate drive and tubular clamping system for a catwalk. The system includes first and second actuators configured to move a skate and a clamp. The system includes a biasing device coupled to the skate and configured to bias the clamp between and open and clamped position based on a tension force between forces applied by the first and second actuators and a clamping threshold force. The first and second actuators may be flexibly coupled to the skate drive and tubular clamping system, such as by cables, and remotely mounted on a trough of the catwalk.
