Technical Details

I acquired one Ice Rock Elephanti from Ice Rock in 2017 and a second from Vertical (Вертикаль) in 2022. The two are the same company.

My Ice Rock Elephanti is 99 mm. tall, 59 mm. wide, 34 mm. thick, and weighs 163 g.

The side plates are irregular shaped stampings made from 2.9 mm. aluminum alloy sheet metal. They are bent inward in a dogleg at the top left, nearly meeting at the 19.5 mm. attachment hole.

The lower portion of the shell supports the pulley assembly. The sheave is a 14.5 mm. wide aluminum U-grooved turning with a 32.5 mm. major diameter. A rounded rope groove reduces the central (minor) diameter to 27.7 mm. The sheave rides on a 6 mm. stainless steel axle made from a semi-tubular rivet. The sheave has a bearing whose details I cannot see without destroying the device.

There is an eccentric cam attached to an axle riveted to the top right of the rear plate. The cam is a plated steel casting with a partial web. The cam has number of small down-sloping conical teeth. The tooth pattern is (3.4)(1S1.2S2)^1(1S1)^2(3) where "S" is a single mud slot. A spring-loaded latch is mounted on the cam. One end clears a slot in the front plate, while the rear has a turned groove that, when the button is pressed from the front, engages a notch in the rear side plate, holding the cam open and disengaging it from action.

The front plate is printed with the Ice Rock logo and a strength rating illustration.

Comments

The Ice Rock is small and lightweight, yet easy to use. The strength ratings are 8 kn per side for the pulley, and 3.5 kn for engaging the cam.

Warning: The Ice Rock should never be used to support human loads.
