Technical Details

I acquired my Orion-Alp (Орион-Альп) from Artyom Babin (Артём Бабин) in 2021.

The Orion-Alp (Орион-Альп) is 109 mm. tall, 55 mm. wide, 79 mm. thick, and weighs 177 g.

This ascender uses a stamped aluminum frame that wraps around one or two ropes. A forged aluminum lever is mounted in the center of the frame, and can be pulled through the back of the frame to allow rigging the rope. The lever is spring loaded so it will automatically return to the operating position. There are truncated conical posts forged on each side of the lever. In use, each of these presses the corresponding rope into a slight detent in the frame. There is a small hole in the back of the lever that one can attach a small cord to to allow remotely releasing the device. Bent steel straps on each side of the frame provide some support for the frame and the bolt that serves as an axle for the lever. The frame and lever are covered with a speckled paint.

One side is printed with the Орион-Альп logo, "Сделано в России" ("Made in Russia"), "01.2009," and "Рмах 2кN."


This is a Russian copy of the Petzl Shunt. Although my particular ascender is new old stock dating from 2009, the same model was available new when I acquired mine in 2021.
