MAESTRO® S
Descender with integrated progress-capture pulley for loads up to 250 kg, compatible with 10.5 to 11.5 mm ropes
The MAESTRO S is a descender designed for technical rescue operations. It makes it easier to manipulate heavy loads when lowering or hauling and can be used in both the primary system or in a backup belay. This versatility allows rescuers to adapt to a variety of different situations they may encounter on the rescue scene. The ergonomic handle and integrated brake enable a comfortably controlled descent. Changing from lowering to hauling is immediate, without the need to transfer the load. The integrated progress-capture pulley has a large diameter sheave mounted on sealed ball bearings, providing 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 up without having to manipulate the handle. The MAESTRO S descender is compatible with 10.5 to 11.5 mm ropes and can handle loads up to 250 kg.
Detailed description
Description
- Great versatility, ideal for technical rescue:
- The locking system with integrated progress-capture pulley allows the same device to be used for lowering and hauling
- Can be used in both a single or twin primary system and in a backup belay (more information on this technique in the Instructions for Use and technical tips at www.petzl.com)
- Lower connection point can be used to create different types of haul systems
- Hole in the handle for installing a remote control cord
- Easy to use:
- Markings on the device make rope installation easy
- Ergonomic handle allows the rope to be released progressively and enables comfortable control of the descent
- Changing from lowering to hauling is immediate, without the need to transfer the load
- The AUTO-LOCK system allows the rope to be blocked automatically when the handle is not in use; once locked, the rope can be taken up without having to manipulate the handle
- Efficient for handling heavy loads:
- Integrated progress-capture pulley with very large diameter sheave mounted on sealed ball bearings; rotates in only one direction for excellent hauling efficiency
- Faceted sheave creates additional friction zones for the rope and provides additional braking when lowering
- Integrated brake on the device to adjust the friction based on the load and the rope diameter
- Compatible with 10.5 to 11.5 mm ropes for handling loads up to 250 kg Other Usage Characteristics:
- Can be used with a 10 mm rope for a working load limit up to 150 kg
- Can handle loads up to 272 kg when used with an 11 mm NFPA-certified General Use rope
