Abstract: A portable ski rope tow system, which is capable of ascending various pitched slopes. The system only needs to be anchored into snow for operation. The system consists of a main drive mechanism, a continuous loop tow rope, rope support posts that include adjustable rope guide sheave wheels, an end post that includes a rope return pulley utilizing a cable puller/come-a-long for tow rope tensioning. The system is equipped with a pull cord safety device, which runs the length of the system. A towrope clamp attached to a climbing harness is needed by the skier/snowboarder to eliminate hand fatigue and mainly to be able to pass through rope guide sheave wheels. Most of the structural components of the system are lightweight, made of aluminum to provide easier mobility, set up and take down.
