Mechanical Prusiks for tree care
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 rope and single rope.
Intuitive to use
The technique is identical to that of a classic Prusik pulley system, and offers an intuitive grip. The device blocks automatically once the friction chain extends.
For efficient movement
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.
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.
Versatile
Use on doubled ropes
ZIGZAG and ZIGZAG PLUS allow use on doubled ropes.
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.
Choosing your mechanical Prusik for tree care
Standard version
ZIGZAG
The lower attachment hole is fixed to ensure alignment of the device with the axis of the worker and to optimize grip.
Version with high-efficiency swivel
ZIGZAG PLUS
The lower attachment hole with high-efficiency swivel ensures stable and correct positioning of the mechanical Prusik and optimal rope glide through the device.
