Regulations and Standards Mountaineering Equipment – Pulleys – Safety requirements and test methods EN 12278 –This standard specifies safety requirements and test methods for pulleys for use in mountaineering including climbing. Definition –One or more sheaves mounted in a block or a body, which can be used to link a rope (in accordance with EN 892) or an accessory cord (in accordance with EN 564) to a connector (in accordance with prEN 12275) to safeguard a mountaineer, and which reduces the friction while the rope or accessory cord is moving under load.
About SAR PULLEY CERTIFICATE OF CONFORMITY WE CERTIFY THAT THE SAR PULLEY CONFORMS TO EN 12278.
SAR PULLEY The SAR PULLEYS have been designed for rescue and technical access. It comes in two styles, single and double. Both styles have swivel cheek/side plates for ease of fitting to rope. –The double pulley double ended connection of this set is mainly used in systems that are pre rigged or as traveler pulleys along twin line cable-ways and Tyrolean’s. It is specific in its use and therefore should be in a kit that the team members know what is required of it. –The single pulley double ended connection is used in systems along with the double pulley, but it is also used in specialist techniques for lowering lines within Tyrolean-type rescue systems. It can be used for all the same uses as the standard single with a few extra where there is a requirement for the twin connections. Do not use rope of a greater diameter than stated on the pulley or subject the pulley to a load greater than the normal working load.

Set-up Pulley System (I) MA = 4:1 Step 1. Place the two pulley with the round connector hole (eye) facing each other. Attach the rope (knot) with the steel screw-gate karabiner to the eye of one of the pulley. Step 2. Make two ‘U’ with the rope as shown.
Set-up Pulley System (II) MA = 4:1 Step 3. Place the rope into the pulley and closed with the steel screw-gate karabiner. Step 4. Final check to ensure that the pulley rope does not cross over each other.

Other Applications Suggested Systems of Use Note: The Delta maillon has been used within these systems to give an even safe loading, this would not happen using a karabiner and could cause the karabiner to fail.
User Guide SAR PULLEY Users should be trained, competent or under the supervision of such a person. It is difficult to estimate the lifespan of the pulley block due to variations in use and care, but in normal usage and with regular cleaning and lubrication it should be in excess of ten years.
User Guide SAR PULLEY Inspect for any signs of deterioration in the condition of the metalwork, wear on the pulley block, distortion or cracking of the cheeks. Ensure the pulley and the cheeks revolve freely. If in doubt withdraw from service and seek advice from a competent person or the manufacturer/supplier. Do not alter the pulley in any way. All repair work should be carried out by the manufacturer/supplier or with their authorization. An examination should be carried out at least every 6 months by a competent person. These inspections should be recorded paying particular attention to areas of potentially high wear such as the pulley wheel, shaft and side plates.
User Guide SAR PULLEY During use, avoid contact with sharp edges and abrasive or hard surfaces. Select components that are compatible with the pulley. In particular it is important that connectors/karabiners are of a similar radius to that of the cheek aperture on the pulley. Always arrange the connector/pulley/rope system so that the forces involved are in the same plane and would not lead to distortion of any of the system components.
User Guide SAR PULLEY Ensue that the usage instructions for other components used in conjunction with this pulley are complied with. Do not use rope of a greater diameter than stated on the pulley or subject the pulley to a load greater than the normal working load.
User Guide SAR PULLEY After use, wash with a mild detergent or disinfectant with a mild sterile solution and rinse with water. Dry and store in a clean dry environment away from any corrosive chemicals or substances. Pulley wheel axles may be lubricated with general purpose oil after cleaning. If the pulley comes into contact with any chemical or corrosive substances wash and dry immediately as stated above. If any damage has been caused to the metal destroy the pulley.
