Midline attachable mechanical Prusik for tree work professionals.
Designed for arborists and tree climbers, the ZIGZAG SHIFT mechanical Prusik simplifies the most complex movements in the canopy with midline attachment. It functions intuitively with the same technique as a Prusik pulley system with friction chains like the ZIGZAG, for handling that quickly feels familiar. The friction chain provides smooth and precise movement between branches. The ZIGZAG SHIFT is designed for use in a stationary rope system without the need for an auxiliary brake and can also be used in a moving rope system. Developed for demanding conditions in the canopy, its design helps limit wear and is repairable with a repair kit, sold separately.
Detailed description
- Easy midline attachment with openable design:
- Midline attachment is possible when the device is connected to the harness, providing freedom and ease of movement within the canopy
- Opening side plate and friction chain design allow the rope to be installed in a spiral motion
- Upper link with two-piece lever keeps the rope inside the chain
- Intuitive handling and efficient movement:
- Functions using the same technique as a Prusik with a friction chain like the ZIGZAG, so it quickly feels familiar
- Release lever allows for smooth and precise rope feed when moving along the rope
- Wide pulley mounted on sealed ball bearings makes it easy to take up slack
- Speed of movement can be controlled by adjusting the pressure on the lever
- Device blocks on the rope when the friction chain extends
- Fixed lower attachment point allows for system alignment and left- or right-handed use
- Versatile:
- Designed for use in a stationary rope system without the need for additional friction, for a simple and compact progression system
- Upper attachment point for the end of the rope makes it possible to use in a doubled rope system
- For long descents or heavy loads, the CHICANE auxiliary brake can be added for increased control and comfort on the descent
- Auxiliary attachment point can be used to connect a second system, shoulder straps, or an SRS chest harness for ascending
- Durable and repairable:
- Components that see the most wear are made with steel for improved durability
- Separated and curved side plates provide better wear resistance
- Repairable, the upper part of the friction chain can be replaced, extending the product's usable life (repair kit sold separately, reference D022QA00)
