The Harken Advance Tech Progress Capture Pulley is a compact double pulley with an integrated cam designed for efficient progress capture in rescue and rope access systems. The built-in cam eliminates the need for separate prusik loops, simplifying mechanical advantage setups while improving speed and reliability during rescue operations. Manufactured from Aerospace-quality anodized aluminum, the Advance Tech provides exceptional durability, corrosion resistance, and smooth performance. High-efficiency sealed ball bearings ensure consistent function even in harsh environments where lower-grade pulleys may fail. Designed for professional rescue teams and technical rope users, the Advance Tech supports rope diameters from 7 mm to 12.5 mm and integrates easily into small mechanical advantage systems used in technical rescue scenarios. Key Features Integrated Progress Capture CamThe built-in cam automatically captures progress during hauling systems, eliminating the need for prusik loops and simplifying rigging. High-Efficiency Ball BearingsSealed ball bearings provide smooth rotation and reliable performance even in demanding rescue environments. Compact All-in-One DesignThe integrated frame and cam create a streamlined pulley system that reduces bulk and shortens the end-to-end length of the system while maintaining high performance. Rope Retention PinsStainless steel pins keep rope secured in the pulley when the system is packed, mitigating tangles and allowing rapid deployment when needed. One-Handed OperationPrecision-tensioned side plates allow rescuers to open and operate the pulley easily with one hand. Low-Profile HardwareFlush fasteners minimize snagging when moving the pulley through complex rigging environments. Complies with regulations (EU) 2016/425 relating to PPE EN567:2013 EN12278:2007 Haul System Strength: Cam Rating 4:1 Haul System Strength - Typical 4:1 system rigged using the Advance Tech with cam engaged on the 4th leg and a standard double Pulleys. The system utilized the becket on the Advance Tech Pulleys. System was pulled end to end using carabiner holes. Cam Rating 4:1 Rope ø Breaking Strength 7mm 2,000 lbf. (8.9kN) 9mm 2,500 lbf. (11.1kN) 12.5mm 4,500 lbf. (20kN) Cam Rating 1:1 Haul System Strength – This configuration is not recommended due to the relatively low strength results, but are included in these instructions to provide the necessary guidance when developing rigging methods. Single rope strand is rigged through the engaged cam and over one sheave. The force is applied between the end of the rope and the Pulleys carabiner hole. Cam Rating 1:1 Rope ø Breaking Strength 7mm 500 lbf. (2.2kN) 9mm 700 lbf. (3.1kN) 12.5mm 1,000 lbf. (4.4kN)
