PETZL – 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.
Description
- Great versatility, ideal for technical rescue:
– locking system with integrated progress-capture pulley allows the same device to be used for descent and hauling
– can be used in both a single or twin primary system and in a back-up belay (more information on this technique in the product’s instructions for use and in technical tips at www.petzl.com)
– lower connection point can be used to create different types of hauling systems
– hole in the handle for installation of a distance control cord - Easy to use:
– easy rope installation, thanks to the markings on the device
– ergonomic handle allows the rope to be released progressively and enables comfortable control of the descent
– immediate shift from lowering position to hauling position without having to transfer the load
– 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
– sheave is faceted, creating additional friction zones for the rope and thus additional braking on descents
– integrated brake on the device to adjust the friction based on the load and the rope diameter
– handling of loads up to 250 kg - Rope compatibility: 10.5 to 11.5 mm diameter
