PETZL MAESTRO S

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

MAESTRO S is a descender designed for technical rescue operations. It facilitates the handling of heavy loads, when lowering as well as lifting, and can be used as a main system and in self-belaying. This versatility allows rescuers to adapt to all configurations encountered at the scene of the intervention. The ergonomic handle and integrated brake allow you to control the descent comfortably. The transition from the lowering position to the lifting position is immediate, without having to recover the load. The integrated locking pulley, with large diameter pulley on sealed ball bearings, guarantees excellent lifting efficiency. 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 the handling of loads up to 250 kg.

Detailed Description

Great versatility of use, ideal for technical rescue:
– locking system with integrated ascending pulley that allows the same device to be used for lowering and lifting,
– it can be used as a single or double main system and in self-belaying (more information on this technique in the information note and in the technical advice on the www.petzl.com website).

Effective handling of heavy loads:
– integrated locking pulley, with large diameter pulley on sealed ball bearings, equipped with a unique direction of rotation for excellent lifting efficiency,
– faceted pulley to increase the friction zones with the rope for additional braking action when lowering,
– brake integrated into the device to modulate the clutch according to the load and the diameter of the rope,
– handling of heavy loads up to 250 kg.
