[ Top | Altochut Version B | Stick-Run | Return to Rope Grabs ]
I acquired this version from KHS Sales in 1988.
The body of the Altochut is made from three irregular 2.5-mm steel stampings. The left side and rear stampings are hinged with a roughly 8-mm hinge pin. The rear stamping swings to close with the right side with a 12-mm knurled bolt. A lightweight safety pivots on the right side stamping to close the joint. Several pins link the two side plates. The top pin slides in a slot, and supports a 20.5-mm knurled roller. The remaining pins are fixed rivets. The second pin supports a drag spring that runs in a groove in the roller, forcing the roller against the rope. The third pin provides a support for the opposite end of the drag spring. The fourth pin supports the cam and cam spring, and the fifth (lowest) pin supports the other end of the cam spring and also acts as a cam stop. The cam is made of 4 pieces of sheet steel riveted together. The inner two are recessed from the outer two to give a somewhat concave cam face. Each piece has notches (six on the outer two, seven on the inner two) cut on the cam face to form cam teeth. A large forged steel piece riveted between the outer cam plates forms an eye to tie in to.
The back of this Altochut is stamped with an arrow pointing upwards and labeled "UP" and the following message:
KOMET ALTOCHUT
USE ONLY WITH RECOMMENDED
5/8" (16 M/M) DIA
POLYPROPYLENE OR NYLON ROPE
ENGAGE ON ROPE WITH
ARROW POINTING UP
MADE IN FRANCE
It also has"7020433" stamped on the rear inside of the right side plate. This may be a serial number.
The Komet Altochut operates on the same principle as a Type 1 Lever Cam Ascender. The cam construction provides an unusual tooth pattern (at least for an ascender). The drag roller helps ensure that the cam grips during a fall by providing resistance to keep the body of the Altochut from free-falling down the rope. The more interesting feature is how the frame opens to accept the rope. The small safety catch does not appear to contribute much.

I acquired this well-used version on eBay in 2005.
Version B has a stamped eye instead of a cast eye; otherwise, it is functionally identical to version A.
The back of this Altochut is stamped with an arrow pointing upwards and labeled "UP" and the following message:
Komet Altochut 310 lbs
Warning: Use only on 5/8" (16 mm) dia
synthetic rope with arrow pointing up.
Do not use unless properly trained. Before use read
understand, and follow manufacturers instructions.
Made in France
The back side of the left side plate hinge has a faint dot-matrix impression that reads "T64 99 26."
I prefer the forged eye found on version A, since it provides a more rounded surface to tie in to.

I acquired this version from Inner Mountain Outfitters in 1999.
The body of the Stick-Run is made from three irregular 2.5-mm steel stampings. The left side and rear stampings are hinged with a roughly 8-mm hinge pin. The rear stamping swings to close with the right side with a 12-mm knurled bolt. A lightweight safety pivots on the right side stamping to close the joint. Three riveted pins link the two side plates. The top pin supports a 17-mm smooth roller. This roller has a 13-mm central hole and a spring inside that tends to center the roller, but allows it to deflect toward the pin in any direction.The second pin provides support for a weak cam spring. The third pin supports the cam. The cam is made of 4 pieces of sheet steel riveted together. The inner two are recessed from the outer two to give a somewhat concave cam face. Each piece has seven cut on the cam face to form cam teeth. A small steel stamping riveted between the outer cam plates forms an eye to tie in to. The cam axle and cam eye rivets have extensions on their left sides. The axle rivet supports stamped lever a strong spring that forces the lever downward against the eye rivet providing a strong holding moment. A small hook in the upper part of the left side plate aligns with a hole in the closure lever, providing a means to disengage this feature.
The back is stamped with an arrow pointing upwards and labeled "UP," "HAUT," "ALTO" and "OBEN" and the following message in dot-matrix format:
KOMET STICK-RUN 646000
DRISSE D10.5mm EN 353-2
DU CORDAGE 3T PA D12mm
made in france549940/042
The back side of the left side plate hinge has a faint dot-matrix impression that reads "DF 54 99 29" and "CE 0333"
The Komet Stick-Run is similar to the Altochut. Its smaller size makes it more convenient.
