PETZL MAESTRO® S descender

PETZL MAESTRO® S Descender

• Versatile design for technical rescue:

  • Integrated progress-capture pulley: Allows the same device to be used for both descent and hauling, providing flexibility for rescue and work operations.
  • Versatile application: Can be used in main systems, two-person systems, or for belay, meeting various technical requirements. (For more technical details, please refer to the product manual and www.petzl.com technical tips.)
  • Multiple hauling system configurations: The lower connection point allows for the setup of different types of hauling systems, increasing operational flexibility.
  • Distance control line hole: A hole on the handle for installing a distance control line, further improving precise control.

• User-friendly operation design:

  • Intuitive rope installation: Clear markings on the device allow for quick and easy rope installation.
  • Ergonomic handle: Designed to allow gradual release of the rope, providing comfortable control of the descent and ensuring safe, smooth operations.
  • Seamless transition: Can be switched immediately from the descent position to the hauling position without shifting the load, greatly improving work efficiency.
  • Auto-lock system: The auto-lock system allows the rope to be locked automatically when the handle is not in use. Once locked, the rope can be taken in without manipulating the handle.

• Efficient handling of heavy loads:

  • Progress-capture pulley: Equipped with a large-diameter sheave on sealed ball bearings for excellent hauling efficiency.
  • Additional friction design: The sheave features a faceted design that creates additional friction zones for the rope, providing more stable braking during descent.
  • Adjustable friction: The integrated brake allows friction to be adjusted based on the load and rope diameter, flexibly adapting to different scenarios.
  • Handles loads up to 250 kg: Stable transport of heavy objects with high reliability.
• Rope compatibility: Supports ropes with diameters from 10.5 to 11.5 mm, suitable for various professional needs.
• Certification: CE, EN 12841 type C, EN 341, NFPA 2500 Technical Use, EAC.
