Technical Details

Artyom Babin (Артём Бабин) sent me this Izhevsk Mechanical Plant Peak (ПИК) ascender in 2021.

The Izhevsk Mechanical Plant Peak is 234 mm. tall, 103 mm. wide, 33 mm. thick, and weighs 286 g.

Cam faceThe shell is a tall irregular shaped stamping made from 3.9 mm. aluminum alloy sheet metal. A 17 mm. diameter rope channel is formed in the upper portion of one side and a smaller cam channel lies opposite. A hole drilled through both sides of the cam channel accepts a 6 mm. semi-tubular rivet. The cam and cam spring are mounted on this rivet. The rivet is centered 52 mm. from the inside of the rope channel.

The handle below the cam has a hard plastic hand grip molded into place. The hand grip has four finger grooves. A 16.2mm. sling attachment hole lies below the handle opening. Another 16.2 mm. hole provides an attachment point just above the cam. The attachment holes are chamferred.

The cam is a steel casting. The cam radius increases from 46 to 59 mm. over an angle of 41°, giving a 20° cam angle. The cam has number of small rounded teeth. The tooth pattern is (4)^13). The cam safety is a machined aluminum lever mounted on a 3 mm. roll pin in the same shell channel as the cam. Unlike most eccentric cam ascenders, the inner cam face radius is constant. A second spring mounted on this roll pin serves as a safety spring. Normally this spring holds the safety where it blocks the cam from opening. When the end of the safety lever is depressed, the opposite end pivots upwards so that the cam is no longer obstructed.

The front of the handle has "ПИК" in raised outlined characters. The rear has "ЩИТП" followed by a down-pointing arrow inside a square, all in raised outlined characters.

Comments

I have large hands, and this ascender fits them well. The finger ribs on the inside of the cam opening are particularly nice and placed perfectly for my hands.

Hundreds of cell phone users complained and asked me to for a simpler, mobile friendly site. In particular, they wanted me to limit each page to a small number of pictures and minimize my use of text. This new site provides what they asked for.
