Technical Details

I acquired this Bornack Track-Attack from Ropes Course Gear and More in 2023.

My Bornack Track-Attack is 195 mm. long, 133 mm. wide, 41 mm. high, and weighs 600 g.

The Track-Attack is a zip-line trolley. It consists of two rollers and a trigger-operated gate mechanism sandwiched between 3.9 mm. aluminum alloy plates. Thew rear plate is one piece and shaped something like a mallet. The front has two plates separated by a 13.5 m. horizontal slot. The upper front plate is bent outwards at the bottom, forming a guide to help place the device on a zip-line. The plate itself sits 23.3 mm. from the rear plate. It houses two rollers mounted on riveted axles. These pulleys are offset toward the rear plate. A pin beneath each pulley has a frustum of a cone on the inside of the rear plate to keep the zip-line. from wedging between the pulley and front plate. There is a plastic piece at the top that keeps one's fingers out of the pulleys if one attempts to grip the top of the device. A parking hook holds the safety carabiner so that it does not drag on the zip-line.

Each ball-bearing roller is stainless steel, 38 mm. in diameter, 17 mm. thick, with a 12.6-mm. wide, 6.3 mm. deep U-shaped groove to run on the zip-line.

The lower front plate houses a spacer and a trigger-operated gate mechanism. The spacer holds the plate 22.5 mm from the rear plate. A plastic trigger linked to a gate arm provides an easy means to open the gate. The gate is a 4 mm. steel arm with a safety roller mounted at about the same height as the slot. The upper portion of the lever has a button-head pin that engages a guide slot in the upper front plate.

The lower portion of the device has a 13 mm. high, 223 m. wide sub-triangular carabiner eye.

The rear plate is etched with "CE 0123," a book-with-an-"i" icon, the Bornak logo, "BORNAK," "www.bornak.de,"TRACK-ATTACK," "Made in EEC," "Patented," "ROPE Ø≤ 13mm," "0109," "⇩," "22 kN," "EN 12278:2007," and "EN 795:2002."

Comments

The track-attach is designed for commercially-operated adventure parks only. Private use is considered improper. It can be used on appropriate steel cables or on static kernmantle ropes.

They eye is small, and many standard carabiners will not fit through the eye. The design intent was that a cows tail would be attached directly, without using a carabiner.

Bornak's Track-Attack manual explicitly forbids my providing except to show how the device is uses.
