The Petzl Ascension is a robust handled ascender designed for efficient rope ascents and occasional hauling tasks. Its ergonomic molded handle ensures a comfortable yet powerful grip, while the toothed cam with a self-cleaning slot maintains performance across various conditions, including frozen or dirty ropes. The device features lower and upper holes tailored for attaching a progress lanyard, foot loop, or integrating into pulley systems.

Understanding the Petzl Ascension

The Petzl Ascension is a handled ascender designed specifically for efficient rope ascents. Built with user comfort and safety in mind, it features:

• Ergonomic Handle: Provides a secure grip and reduces hand fatigue during long ascents.
• Toothed Cam with Self-Cleaning Slot: Ensures consistent performance on ropes of varying conditions, including wet, dirty, or frozen lines.
• Multiple Connection Points: Lower and upper holes are available for attaching progress lanyards, foot loops, or connecting to other components in mechanical advantage systems.

Its lightweight design and durable construction make it a favorite among professionals who require reliability in demanding environments.

What is the RAD System?

The RAD System is a versatile and compact mechanical advantage setup designed for efficient rope travel in both directions—ascending and descending. Unlike traditional systems, the RAD setup enables quick transitions between modes, providing unmatched flexibility for tasks like rope access, confined space work, and self-rescue.

Core Components

• Petzl Ascension: The primary device for ascending.
• Petzl Rig or Petzl I’D: Functions as the descender in the system.
• Petzl Partner or Mobile Pulley: Adds efficiency to hauling operations.
• Petzl OK Carabiners: Ensure secure connections throughout the system.

The RAD System allows users to switch seamlessly between ascending and descending, making it an invaluable tool for mobile rope operations.

How to Use the Petzl Ascension in a RAD System

1. Setting Up the System

Begin by rigging your rope through the descender (Petzl Rig or I’D) at the anchor point. Attach the Petzl Ascension to the rope, ensuring the toothed cam is properly engaged. Use a foot loop connected to the Ascension for added efficiency during the ascent.

2. Ascending the Rope

Grip the handle of the Petzl Ascension firmly while applying downward pressure with your foot in the foot loop. Slide the Ascension upward, ensuring it locks securely into place with each movement. Repeat this process in a smooth, rhythmical motion to ascend efficiently.

3. Transitioning to Descent

Once you reach your desired height, transition to the descender. Disconnect the Petzl Ascension from the rope, and engage the descender to safely lower yourself or your load.

Practical Applications of the RAD System

1. Work-at-Height Operations

The RAD System is widely used in industrial and maintenance tasks, where rapid ascent and descent capabilities enhance efficiency and reduce downtime.

2. Rescue Scenarios

In emergency situations, the system enables rescuers to quickly reach victims and transition to lowering or hauling operations without needing to reconfigure their setup.

3. Confined Space Entry

The compact nature of the RAD System makes it ideal for navigating tight spaces where larger setups are impractical.

Safety Tips for Using the Petzl Ascension

• Inspect Equipment: Regularly check the toothed cam, handle, and connection points for signs of wear or damage.
• Use Proper Technique: Maintain a firm grip on the handle and ensure the Ascension is securely engaged on the rope before applying weight.
• Practice Transitions: Familiarize yourself with the process of moving between ascent and descent modes to ensure smooth and safe operation.
• Use Static Rope: The RAD System performs best with low-stretch static ropes, which provide better control and minimize energy loss.
