PETZL lowering device MAESTRO S

Product detailed description

MAESTRO S is a self-braking lowering and hauling device designed for technical rescue operations. It facilitates handling heavy loads during 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 enable comfortable and controlled load lowering. The transition from lowering to hauling mode is instantaneous, without the need to transfer the load. The integrated pulley rotates in one direction and locks in the opposite direction. A 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 without requiring any action on the handle. MAESTRO S is compatible with ropes ranging from 10.5 to 11.5 mm in diameter and can handle loads of up to 250 kg.

• The 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 both lowering and hauling
• Can be used in a single or double primary system as well as in a backup system (more information on this technique can be found in the product user manual and technical tips at www.petzl.com)
