Petzl MAESTRO S pulley

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

Great versatility, ideal for technical rescue:

• A self-locking 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 retrieving
• Can be used in a single or double primary system and also in a belay system (more information about this technique in the product user manual and technical tips at www.petzl.com )
• The lower connection hole can be used to create different types of hoists
• Hole in the handle for installing a cord for remote control

Easy to use:

• The ergonomic handle allows gradual release of the rope and enables convenient control of the launch.
• Instant change from lowering mode to pulling mode without the need to shift the load
• The AUTO-LOCK system allows automatic locking of the rope when the handle is not in use

Effective for handling heavy loads:

• The pulley has ground facets that create additional friction zones for the rope and thus better braking during lowering.
• The integrated brake regulates friction based on the load and rope diameter
• Handling loads up to 250 kg
• Compatibility with ropes: diameter 10.5 to 11.5 mm
