ZIGZAG® - Petzl - d022aa

Mechanical Prusik for tree care

The ZIGZAG mechanical Prusik allows the user to move around efficiently in a tree using classic Prusik pulley system technique. The friction chain provides precision and fluidity when moving around. The pulley is mounted on sealed ball bearings to allow the slack to be taken up easily. Can be used on either doubled ropes or a single rope, providing great versatility. The lower attachment hole is fixed to ensure alignment of the device with the axis of the worker and to optimize grip.

Intuitive Climbing Device for Tree Movement

Designed for arborists, this climbing device replicates the classic Prusik pulley system with enhanced features for efficiency, versatility, and durability, ensuring smooth and controlled tree navigation.

Intuitive Usage

• Classic Technique with Automatic Lock: Operates like a classic Prusik pulley system but with an automatic locking feature that engages once the friction chain extends, ensuring safety and ease of use.

Efficiency in Movement

• Smooth Rope Feed: The release lever allows for precise control of movement, with the speed adjustable by varying pressure on the lever.
• Slack Management: Easy slack uptake thanks to a pulley mounted on sealed ball bearings and curved side plates that facilitate smooth rope passage.
• Optimal Alignment: The lower attachment hole is fixed to ensure the device aligns with the worker’s axis, optimizing grip and efficiency.

Versatility

• Adaptable for Different Techniques: Suitable for use on doubled ropes or a single rope with the CHICANE accessory, which increases friction on descents, and compatible with KNEE ASCENT assemblies to aid ascent.
• Multiple Attachment Options: Features an upper attachment hole for the rope end (doubled rope usage) or for the CHICANE auxiliary braking device (single rope usage), plus an auxiliary attachment hole for adding a ZILLON lanyard or connecting a second system.

Durability

• Robust Construction: Made with steel to enhance durability and withstand rigorous use.
• Wear Resistance: Separated and curved side plates reduce wear and extend the device’s lifespan.

Compatibility and Standards

• Rope Compatibility: Compatible with ropes ranging from 11.5 to 13 mm in diameter, accommodating a variety of rope types used in arboriculture.
• Compliance: ZIGZAG device complies with ANSI Z133 standards for safety in arboricultural operations.
