Petzl Maestro S

Product description

MAESTRO S is a self-locking lowering and retrieval device designed for technical rescue operations. It facilitates the handling of heavy loads when lowering or retrieving and can be used in both primary and locking systems. This versatility of use allows rescuers to adapt to any situation they may encounter during a rescue. The ergonomic handle and integrated brake allow comfortable controlled lowering of the load. The transition from start-up to pull-up mode is instantaneous, without the need to switch loads. The integrated pulley rotates in one direction and locks in the opposite direction. The large-diameter disc mounted on encapsulated ball studs ensures excellent pulling efficiency. The AUTO-LOCK system automatically locks the rope when the handle is not in use. After locking, the rope can be lifted up without manipulating the handle. MAESTRO S is compatible with ropes with a diameter of 10.5 to 11.5 mm and allows handling loads up to 250 kg.

Great versatility, ideal for technical rescue:

• Self-locking system with integrated pulley that rotates in one direction and locks in the opposite direction allows the same device to be used for both lowering and pulling
• Can be used in a single or double primary system and also in a locking system (more information on this technique in the product manual and technical tips at www.petzl.com)
• The lower connection hole can be used to create different types of pulleys
• Hole in the handle for installing a cord for control from a greater distance

Easy to use:

• Easy rope installation thanks to marking on the device
• The ergonomic handle allows gradual slackening of the rope and allows comfortable control of the lowering.
• Instant change from start-up mode to pull-up mode without the need to switch loads
• The AUTO-LOCK system allows the rope to be automatically locked when the handle is not in use

Efficient for handling heavy loads:

• Large diameter integrated pulley with one-way locking, mounted on encapsulated ball bearings; rotates in only one direction for excellent pulling efficiency
• The pulley has ground facets that create additional friction zones for the rope and thus better braking when lowering.
• Integrated brake regulates friction based on load and rope diameter
• Handling loads up to 250 kg
• Compatible with ropes: diameter 10,5 to 11,5 mm
