Fitting of the Type I and Type II Pulleys on the Cable, Pole or Beam

Installation of the Type I and Type II Pulleys

Fitting Type I Pulley

The Type I Pulley is fitted to the Secondary Anchor Point, and provides both support and a means of redirection for the Reduction Line.

The Type I Pulley is required for both 1:1 and 2:1 Reduction Ratio setups. The Type I Pulley may be fixed horizontally or vertically to a solid surface, or to be clamped to a cable. The Type I Pulley incorporates dedicated line attachment points for dead-end loops.

Fit the Type I Pulley as follows:

  • Always position the Type I Pulley higher than the zip line. A minimum of 1.0 meter (40”) is recommended.
  • Ensure the position of the pulley will not allow contact or interference between the rider and any lines or equipment.
  • Ensure the change in angle of the Reduction Line as it passes through the pulley is minimized – this may require mounting the pulley assembly on an angle towards the Brake Trolley.
  • Ensure the Type I pulley assembly is mounted on a load bearing surface capable of withstanding all applicable load bearing requirements.
  • Ensure that the Reduction Line is routed cleanly and in line through the pulley system, to prevent contact with any surface other than the pulley sheaves.

Fitting Type II Pulley

The Type II Pulley is fitted between the zipSTOP Brake Unit and the Type I Pulley as required to provide support and redirection for the Reduction Line and connections to the Braking Line.

The Type II Pulley is only required on the 2;1 Reduction Ratio set-ups. Fit the Type II Pulley so as to ensure the position of the pulley will not allow contact or interference between the rider and any lines or equipment.

It is recommended that an overhead support line and link be used with the Type II Pulley to reduce the risk of line entanglement.
