Petzl MAESTRO S descender
MAESTRO S is a self-braking descent and hauling device designed for technical rescue operations. It facilitates handling heavy loads when lowering or hauling and can be used in both primary and backup systems. This versatility allows rescuers to adapt to any situation they may encounter during a rescue. The ergonomic handle and integrated brake allow for comfortable, controlled lowering of a load. Transitioning from lowering to hauling mode is instantaneous, without needing to re-load the system. The integrated pulley rotates in one direction and locks in the opposite direction. The large-diameter sheave, mounted 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 lifted upwards without manipulating the handle. MAESTRO S is compatible with ropes from 10.5 to 11.5 mm in diameter and allows handling loads up to 250 kg.
Great versatility, ideal for technical rescue:
- Self-braking system with an integrated pulley that rotates in one direction and locks in the opposite direction allows the same device to be used for lowering and hauling
- Can be used in a simple or doubled primary system, as well as in a backup system (more information on this technique in the product's user manual and technical tips at www.petzl.com)
- The lower attachment hole can be used to create different types of pulley systems
- Handle hole for installing a cord to control from a distance
Easy to use:
Easy rope installation thanks to the markings on the device- The ergonomic handle allows for gradual rope release and comfortable control of descent.
- Instantaneous transition from lowering to hauling mode without needing to re-load the load
- The AUTO-LOCK system allows the rope to be automatically locked when the handle is not in use
Efficient for handling heavy loads:
Integrated, single-direction locking pulley of large diameter, mounted on sealed ball bearings; rotates only in one direction for excellent hauling efficiency- The pulley has machined facets that create additional friction zones for the rope, thus improving braking during descent.
- The integrated brake regulates friction based on the load and rope diameter
- Handling loads up to 250 kg
- Rope compatibility: diameter 10.5 to 11.5 mm
