A carriage is described for utilization along a highline for the purpose of guiding a mainline along the highline between a yarder at a landing and an anchor point along an adjacent hillside. The carriage is suspended by freewheeling sheaves on the skyline. The mainline also extends through the carriage. A highline clamp and mainline clamp are provided within the carriage and are actuated to clamp and release the highline and mainline relative to the carriage frame. Actuation is accomplished through the mainline winch at the yarder by producing tension along the mainline and by moving an abutment on the mainline against the actuator.
