• Version with high-eff iciency swivel

• Standard version

The lower attachment hole with high-efficiency

swivel provides stable and correct positioning

of the mechanical Prusik and optimal rope glide

through the device.

The lower attachment hole is fixed to maintain

alignment of the device with the axis of the

worker and to optimize grip.

Descenders

Mechanical Prusiks for Tree Care

• Versatile

• For eff icient movement

• Intuitive design

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

can be used 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.
