In technical rope rescue and rigging, horizontal systems present unique challenges and opportunities. The use of dynamic directionals allows riggers to create efficient and adaptable solutions for traversing and accessing horizontal spans. This blog dives into the application of horizontal rigging with three dynamic directionals, exploring their setup, operation, and benefits.
What Are Dynamic Directionals?
Dynamic directionals are points within a rigging system that can move or adjust dynamically to manage load transitions and directional changes. These elements provide flexibility, making them ideal for scenarios where static anchors are not sufficient.
Applications of Dynamic Directionals:
- Spanning horizontal distances, such as across ravines or industrial spaces.
- Managing complex loads requiring directional changes.
- Maintaining tension and balance in traverses or hauling operations.
The Power of Three Dynamic Directionals
Using three dynamic directionals in horizontal rigging provides enhanced control and flexibility. Here’s how they function:
- Primary Directional:
- Anchors the system’s starting point.
- Often a high directional to minimize friction and optimize control.
- Intermediate Directional:
- Manages transitions dynamically, providing stability during load movement.
- End Directional:
- Acts as the terminal anchor, ensuring secure load completion.
These elements work together to create a smooth and controlled path for loads, even in challenging environments.
Setting Up Horizontal Rigging with Dynamic Directionals
1. Planning the System Path
- Identify and secure anchor points for the primary, intermediate, and end directionals.
- Account for terrain variations and load characteristics.

2. Deploying Directionals
- Use a high directional like a tripod or monopod for the primary anchor.
- Incorporate pulleys at the intermediate and end points to facilitate smooth transitions.

3. Rigging the Main and Backup Lines
- Use static kernmantle ropes for primary and backup lines to ensure strength and low stretch.
- Secure lines to rigging plates for efficient load distribution.
