Technical Details

Ondřej Belica of Climbing CZ sro sent me this Singing Rock/Kong Indy Evo Plus in 2022.

My Singing Rock / Kong Indy Evo Plus is 201 mm. tall, 57 mm. wide, 44 mm. thick, and weighs 485 g.

This descender consists of a fixed plate in the rear and a pivoting plate in the front with two bollards and an over-travel stop assembly consisting of a cam, folding handle, and connecting arm. The plates are each 3.4 mm. thick.

Starting at the top of the fixed plate, the over-travel stop cam is mounted on a shoulder rivet near the top. The head and shoulder of this rivet fit into a notch in the pivoting plate.

The upper bollard sits 40 mm. lower, where it is riveted through its center. This bollard is made from aluminum alloy. It is 41 mm. in diameter and 14 mm. thick. A projection in the bollard fits into a hole in the fixed plate to prevent rotation. The rope groove is U-shaped, 10 mm. wide, and 3 mm. deep. The pivoting plate has a second notch that engages a shoulder area on the mounting rivet. The notches provide support to keep the pivoting side plate from bending open during descent.

The lower bollard is truncated pear-shaped with a 40 mm. diameter pruning surface, 14 mm. thick, and made from aluminum alloy. Its form is that of a circle truncated by two chords. The lower bollard rotates on a shoulder rivet attached to to the fixed side plate about 48 mm. below the upper bollard. This bollard has a 2 mm. deep, 9 mm wide V-shaped groove on its circular peripheral arcs.

A handle assembly mounted on the outside of the fixed side plate rotates on the same rivet as the lower bollard. The friction from the passage of the main rope causes the lower bollard to rotate, rotating the handle and pulling the connecting rod down. The handle is used to keep the cam disengaged during normal descent, but pulling the handle too far brings the end of the autostop cam against the rope, slowing the descent.

The attachment point is a 15 by 27 mm. oval hole near the bottom of the fixed plate. The hole is oriented vertically. The pivoting plate has a hook with a spring-loaded stamped stainless steel safety.

The pivoting side plate is marked with an up-pointing arrow logo, "singing rock," "FREE ROPE," "CE0068," a book-with-an-"i" icon, "EN12841/C : 06," "100 kg," a rope icon, "•Ø10÷12 mm," "200 kg," a rope icon, "•Ø10÷12 mm," "EN341/2A : 11," "MIN -4 °C," 30 ÷ 100 kg," "H MAX 100 m," "KONGLINE Ø 10.5/11 mm,", "read manufacturer info!", "LOADED ROPE," "Made in Italy," "222743 0081," a factory icon, and "04/2022." The connecting arm is printed with the Kong logo, "INDY EVO PLUS" and "801 040." The inside of the fixed plate is printed with "made by KONG S.p.A.," "Via XXV Aprile, 4-23804", "Monte Marenso (LC) ITALY," and a rigging illustration.

Comments

The folding autostop handle is differs markedly from most stop bobbins, and anyone making the transition would be wise to spend time to develop new "muscle memory" before using the new version in the field.

Kong makes the Indy Evo Plus for Singing Rock, so this is identical to the Kong Indy Evo Plus.
