Cable Ascender

Technical Details

I acquired my Russian cable from Ed Sira at the 1993 Old Timers Reunion.

The Russian cable is 90 mm. tall, 45 mm. wide, 33 mm. thick, and weighs 175 g. The frame is bent from sheet steel , and the cam is milled from steel plate. The cam face has three shallow grooves, giving the ascender two low-relief teeth. The cam axle is a steel pin that is retained by a steel cable passing through a hole in the end of the pin. Two sets of holes in the shell allow the cam to be positioned for climbing different size cable.

There are no markings on this ascender.

Comments

This ascender is not as crudely made as it first appears, since most of the illusion is due to the loose cable ends.

The ascender is designed to be used on cable, but can also be used on 9 mm. rope if the cam is in the outer position.

Technical Details

I acquired my Russian rope ascender from John E. Weinel, Inc. at the 1994 Old Timers Reunion. I acquired another in 2017 as part of Bob Thrun's collection.

The Russian rope ascender is 46 mm. tall, 72 mm. wide, 28 mm. thick, and weighs 97 g. The frame and cam are milled from aluminum, and the cam is permanently bolted to the frame. A swinging side plate is riveted to the upper side of the frame.

There are no markings on this ascender.

Comments

John Weinel found this nice little ascender in 1994, and imported it as a novelty device. I like the design because it is different than many of the western designs. After the rope is inserted, the side plate is closed and slings are attached with a carabiner or maillon that passes through both the cam eye and the oval hole in the side plate. As the climber climbs, the side plate rotates with the cam. The oval hole allows this, even though the two parts are pivoting about different points. One disadvantage of this system is that it is not conducive to sewing slings to the ascender.

As with all short ascenders, this one rotates significantly in use, resulting in lost motion.
