MAESTRO L is a descender designed for technical rescue operations. It facilitates the handling of heavy loads, both in descent and hauling, and can be used as either a main system or a belay backup.
This versatility allows rescuers to adapt to all configurations that may be encountered at the intervention site. The ergonomic handle and integrated brake allow comfortable control of the descent. Switching from the descent position to the hauling position is immediate, without having to take up the load again.
The integrated pulley-blocker, with a very large diameter sheave on sealed ball bearings, ensures excellent hauling efficiency. The AUTO-LOCK system automatically locks the rope when the handle is not in use. Once locked, the rope can be taken in without having to operate the handle.
The MAESTRO L descender is compatible with ropes from 12.5 to 13 mm and allows the handling of loads up to 280 kg.
Main features
- Great versatility of use, ideal for technical rescue:
- locking system with integrated pulley-blocker allowing the same device to be used for both descent and hauling,
- works as both a simple or double main system and as a back-up belay (more information on this technique in the technical instructions and in the technical advice at www.petzl.com),
- lower connection point allowing different types of pulley systems to be set up,
- hole in the handle allowing a remote control cord to be installed.
- Ease and simplicity of use:
- easy rope installation, thanks to the markings indicated on the device,
- ergonomic handle allowing the rope to be progressively released and the descent to be comfortably controlled,
- immediate transition from descent position to hauling position, without having to take up the load again,
- AUTO-LOCK system allowing the rope to be automatically locked when the handle is not in use. Once locked, the rope can be taken in without having to operate the handle.
- Efficiency when handling heavy loads:
- integrated pulley-blocker, with a very large diameter sheave on a sealed ball bearing, featuring a single direction of rotation providing excellent hauling efficiency,
- faceted sheave allowing additional friction zones with the rope for extra braking during descent,
- brake integrated into the device to modulate friction according to load and rope diameter,
- handling of heavy loads up to 280 kg.
- Rope compatibility: 12.5 to 13 mm diameter.
