Abstract
A skate drive system for a catwalk having a skate and a clamping assembly. The system includes a primary actuator and a secondary actuator. The primary actuator is configured to apply a drive force to first and second cables to move the skate along a trough of the catwalk. The secondary actuator is configured to apply a tension force to at least one of the first and second cables independent of the primary actuator to actuate the clamping assembly from an unclamped position to a clamped position.
Claims18
A skate drive system for a catwalk, comprising:
- a skate configured to move a tubular along a trough of the catwalk;
- a clamp assembly coupled to the skate and configured to clamp the tubular to the skate;
- a primary actuator coupled to the clamp assembly by a first cable and a second cable, wherein the primary actuator is configured to move the skate and the clamp assembly via the first and second cables along the trough;
- and
- a secondary actuator coupled to at least one of the first and second cables and configured to apply a tension force to at least one of the first and second cables to move the clamp assembly between an unclamped position and a clamped position.

A method actuating a skate drive system of a catwalk, comprising:
- actuating a primary actuator to apply a drive force to a first cable to move a skate and a clamping assembly along a trough of the catwalk in a first direction;
- actuating the primary actuator to apply a drive force to a second cable to move the skate and the clamping assembly along the trough in a second, opposite direction;
- and
- actuating a secondary actuator independent of the primary actuator to apply a tension force to at least one of the first and second cables to move the clamp assembly from an unclamped position to a clamped position to clamp a tubular to the skate.
