Advance Tech Progress Capture Pulley

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 Cam
  The built-in cam automatically captures progress during hauling systems, eliminating the need for prusik loops and simplifying rigging.
• High-Efficiency Ball Bearings
  Sealed ball bearings provide smooth rotation and reliable performance even in demanding rescue environments.
• Compact All-in-One Design
  The 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 Pins
  Stainless steel pins keep rope secured in the pulley when the system is packed, mitigating tangles and allowing rapid deployment when needed.
• One-Handed Operation
  Precision-tensioned side plates allow rescuers to open and operate the pulley easily with one hand.
• Low-Profile Hardware
  Flush 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 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.
