Version with high-efficiency swivel
The lower attachment hole with high-efficiency swivel ensures stable and correct positioning of the mechanical Prusik and optimal rope glide through the device.
The lower attachment hole is fixed to ensure alignment of the device with the axis of the worker and to optimize grip.
Mechanical Prusiks for tree care
For efficient movement
Intuitive to use
Use on a single rope They can also be used on a single rope, thanks to the CHICANE accessory, which offers more friction on the descent, and the KNEE ASCENT assemblies, which facilitate the ascent.
Slack easily taken up The pulley is mounted on sealed ball bearings to allow the slack to be taken up easily when moving around. The widely spaced side plates also contribute to smooth rope glide.
Use on doubled ropes ZIGZAG and ZIGZAG PLUS allow use on doubled ropes.
Smooth, precise rope feed The release lever is mounted on a spring, for great precision when moving around. Adjusting the pressure on this lever controls the speed of movement.
The technique is identical to that of a classic Prusik pulley system, offering immediate usability. The device locks automatically once the friction chain is extended.
Mechanical Prusiks allow arborists to optimize their movement within a tree. They are user-friendly and intuitive to use. To meet a variety of needs, they can be used on doubled ropes or a single rope.
