Overview


Ural-Alp
(#117)

Technical Details

I acquired my Ural-Alp from John E. Weinel, Inc. in 1995.

The Ural-Alp is 65 mm. tall, 92 mm. wide, 30 mm. thick, and weighs 101 g. The rope channel is 15 mm. wide. The cam radius increases from 30 to 35 mm. over an angle of 18°, giving a 26° cam angle. The cam has no teeth; instead it has a U-shaped groove that fits the rope nicely. There is a hole in the spine that serves no purpose that I can determine.

The rear of the shell is stamped with ROPE," "WIRE HAWSER," and "Ø 6-13MM," all in a circle, and "Ж1-94." The cam is stamped "URAL-ALP" in a rounded rectangle on the front side and "TITANIUM" in a rounded rectangle on the rear.

Comments

The Ural-Alp is a nicely made aluminum ascender from Russia. Because of the shape of the cam, the rope must be rigged from the bottom up. The large clearance makes this easy.

The toothless cam probably requires having the long lever arm found on this ascender. Once loaded, the long arm causes the ascender to rotate almost 90 degrees, so quite a bit of motion is lost. The cam is spring-loaded, so the ascender tends to stay in place when unloaded.

Technical Details

I received this ascender from Ural Sport (Serguei Khramtsov’s eBay store) in October 2003.

The Ural-Alp Supplemental is 70 mm. tall, 87 mm. wide, 31 mm. thick, and weighs 85 g. The rope channel is 16 mm. wide. The cam has no teeth; instead it has a U-shaped groove that fits the rope nicely. This probably requires the long lever arm found on this ascender. The cam is spring-loaded, so the ascender tends to stay in place when unloaded. A spring-wire arm on the cam flips up to provide some token assistance in keeping the cam from over-opening while climbing.

The shell is stamped "1,5 kN," "RUSSIA URAL-ALP" and "KOZLOV DESIGNS"

Comments

This is another nicely made aluminum ascender from Russia. Unlike the previous Ural-Alp, the rope can be rigged from the top down or the bottom up. Once loaded, the long arm causes the ascender to rotate almost 90 degrees, so quite a bit of motion is lost. The spring arm is too weak for me to rely on it, since it easily flips down to the out-or-service position.

Serguei wrote to emphasize, "The device is not rated to be used alone and must be used as additional device only." Later, in 2005 he sent me some post-test photos. His note accompanying theo photos said the following:

"#4 Standard test for ascenders with static load min 400kg. Ascender got a damage by the load 380 kg. It is impossible to unlock the device. The device didn't pass a test and must be used as additional device only."

Technical Details

I acquired my Ural Alp 10.35 from Marina Khramstova (Марина Храмцова) in 2018.

The Ural Alp 10.35 is 65 mm. tall, 113 mm. wide, 28 mm. thick, and weighs 98 g. The rope channel is 15 mm. wide. The cam has no teeth; instead it has a U-shaped groove that fits the rope nicely. This probably requires the long lever arm found on this ascender. The cam is spring-loaded, so the ascender tends to stay in place when unloaded.

The inside of the shell is stamped with "RUSSIA" and "URAL-ALP" inside a rectangle. The rear is stamped with "KOZLOV DESIGNS," also inside a rectangle.

Comments

This is another nicely made aluminum ascender from Russia.

The revised shell design simplifies rigging, as the cam can he opened enough to just let the rope drop into place.

When loaded, the long arm causes the ascender to rotate almost 90 degrees, so quite a bit of motion is lost, greatly reducing climbing efficiency.
