Description

Descender with integrated locking pulley for loads up to 250 kg, compatible with 10.5 to 11.5 mm ropes

MAESTRO S is a descender designed for technical rescue operations. It facilitates the handling of heavy loads, in rappelling as well as in hoisting, and can be used as a main system and in self-belay. This versatility allows rescuers to adapt to all configurations encountered at the scene of the operation. The ergonomic handle and integrated brake allow convenient control of rappelling. Transition from rappelling to lifting position is immediate, without having to retrieve the load. The integrated blocking pulley, with a large-diameter sheave on sealed ball bearings, ensures excellent lifting performance. The AUTO-LOCK system automatically locks the rope when the handle is not in use. Once locked, the rope can be retrieved without having to use the handle. The MAESTRO S descender is compatible with ropes from 10.5 to 11.5 mm and allows handling of loads up to 250 kg.

Detailed description

Great versatility of use, ideal for technical rescue:
– locking system with integrated locking pulley that allows the same device to be used for rappelling and lifting,
– is used as a single or double main system and in self-belaying (more information on this technique in the information note and technical tips at www.petzl.com).
– lower connection point to make different types of recovery.
– hole in the handle to install a remote control lanyard.
Ease and speed of use:
– easy installation of the rope, thanks to the markings indicated on the device,
– ergonomic handle that allows you to progressively release the rope and comfortably control the rappel,
– immediate transition from rappelling position to lifting position, without having to retrieve the load,
– AUTO-LOCK system that allows the rope to be automatically locked when the handle is not in use. Once locked, the rope can be retrieved without having to use the handle.
Effectiveness in handling heavy loads:
– integrated locking pulley, with large-diameter sheave on sealed ball bearings, equipped with a unique direction of rotation for excellent lifting performance,
– faceted sheave to increase friction zones with the rope for additional braking action in rappelling,
– brake integrated to the device to modulate friction according to load and rope diameter,
– handling of heavy loads up to 250 kg.
Rope compatibility: 10.5 to 11.5 mm diameter.
