Parallel Use of MAESTRO, I’D, or RIG Descenders

Using MAESTRO, I’D, or RIG Descenders in Parallel by a Single Operator

The MAESTRO, I’D, and RIG descenders offer versatility for rescue operations, particularly in scenarios involving long rope lengths or smaller teams. When used in parallel, these devices enable a single operator to control two systems simultaneously, streamlining operations while maintaining efficiency. This approach is especially useful in complex rescues requiring precise control and reduced system extension risks.

Lowering use

Choosing an anchor

For optimal device function, we recommend that you use flexible anchors such as slings, ropes or wire rope strops to enable proper orientation of the descenders or of the PAW. The PAW enables a more ergonomic system setup. For greater ease of use, MICRO SWIVELs may be used to attach the descenders to the PAW.

Backing-up the lowering system

A lowering back-up system may be added to your system depending on the situation and your risk assessment. This system enables the requirements of the EN 12841 certification to be met by the addition of an EN 12841 type A component.

Advantages of Parallel Descender Use

Even Load Distribution: The load is evenly shared across both descenders, reducing strain on individual devices.
System Stability: In the event of rope failure, potential system extension is minimized, enhancing safety.
Simplified Operation: A single operator can effectively manage two descenders, optimizing manpower in smaller teams.

Disadvantages to Consider

Shared Risk Exposure: Ropes positioned closely together are simultaneously exposed to hazards, such as abrasion or falling debris.
Backup Requirement: A backup operator is essential for monitoring and mitigating risks during operations.
Risk Assessment: Additional safety measures, such as independent backups, may be required based on situational needs.

Configurations for Lowering Operations

Anchor Selection:
Optimal device performance relies on flexible anchors like slings, ropes, or wire rope strops. Using a PAW connection plate can enhance ergonomic setup and ensure proper device orientation. Adding MICRO SWIVELs can further improve functionality by preventing rope twists during lowering.

Backing Up the Lowering System:
Incorporating a backup system enhances safety and ensures compliance with EN 12841 certification. This typically involves adding an EN 12841 Type A component to secure the system against failures.

Configurations for Raising Operations

Rescue Efficiency:
Using two RESCUCENDERS attached to a double pulley, such as the TWIN, GEMINI, or SPIN L2, significantly improves hauling efficiency. This setup reduces potential rope elongation while evenly distributing the load on the anchors, making it ideal for scenarios where precision and efficiency are paramount.

Practical Applications

Parallel descender systems are invaluable in technical rescues where long ropes and limited team sizes demand efficient, controlled operations. By combining the MAESTRO, I’D, or RIG descenders with a well-thought-out anchor and pulley setup, rescue teams can achieve greater safety and effectiveness.
