RPM Shackles & Components


Compact system – Only 32cm from end to end when compressed.

Modular – Cartridges can be exchanged to reconfigure the RPM system for a wide range of uses.

Dual Control – Prusik can be installed at either end of system, for control by either operator being lowered, operator at top anchor, or both operators simultaneously.

RPM bodies feature swivel components for torsion resistance.

Bespoke eye-to-eye friction hitch cord is matched to side plates for effective Prusik minding function with minimum ‘sit back’ between lifts.

Low stretch 10mm cord and sealed ball bearings in sheaves ensure efficient hauling.

Easy-to-use locking pins for simple connection/disconnection of friction hitch cord.

Available in 15m or 30m rope length versions.

The RPM System is a high strength, modular pulley and shackle system that gives a 4:1 mechanical advantage and increased efficiency when lifting, lowering, moving and controlling a load.
It can be used to haul or lower, supplies or personnel from either end of the rope system and is strong enough for heavy work such as pulling All-Terrain-Vehicles out of ditches.
The compact design makes it suitable for applications with restricted headroom, such as Urban Search and Rescue (USAR), silo/manhole rescue and use with tripods.
A range of different cartridges fit the modular RPM bodies. A single sheave cartridge accepts a single rope of up to 16mm diameter, or two 11mm ropes. A double sheave cartridge accepts an 11mm rope reeved twice. The Rigging Plate cartridge allows additional components to be rigged above or below an RPM body.
The Twin Body RPM allows complex rigging set ups such as backed up trolley systems with lifting and lowering capacity.
