Aluminum Alloy Detachable Rope Grab

A high-performance detachable rope grab designed for high-altitude fall protection, rescue hauling systems, and rope access techniques. The core features a quick-release cam structure secured by a self-locking safety pin, breaking the limitations of traditional equipment; it can be quickly installed or removed at any position along the rope, even when the rope is under full tension. The cam uses leverage to firmly press the rope against the inner wall for braking, providing strong grip without damaging the rope sheath. It has passed rigorous inspections for CE EN 353-2 industrial fall arrest and XF 494-2023 standards.

Key Features

• Mid-rope Quick-release Installation: Features a locking pin combined with a detachable cam design, eliminating the need to thread from the rope end. It can be snapped on or removed in seconds, even while the rope is under tension.

• Smooth Mechanical Cam Braking: Utilizes cam and curved inner wall clamping for braking. With no sharp teeth, it minimizes wear on the rope sheath caused by repeated loading.

• Dual Operational Modes:

  • Hauling System Progress Capture: Functions as a progress capture device in mechanical advantage systems (e.g., 3:1, 5:1) to prevent rope slippage during hauling.

  • Guided-type Mobile Fall Arrester: Provides mobile fall protection for operators, moving smoothly with the user and locking instantly upon a fall.

• Aviation-grade Lightweight/Durable Structure: 7075 aluminum alloy body with stainless steel core components; weighs only 154g with a breaking strength of 15kN.

Safety Guidelines

• Fall Arrester Usage: During operation, the device must always be kept above the user to avoid slack rope, thereby minimizing potential free-fall distance and preventing pendulum impact.

• Backup Protection Recommendation: When used as an ascender or rope grab for advancement, it is strongly recommended to use it in conjunction with an independent backup fall protection system.

• Environmental Maintenance: Regularly inspect the cam surface and rope channel to prevent the accumulation of mud, grit, or debris, ensuring optimal gripping performance.
