In certain training or educational situations, a system may be installed to mitigate excessive descent speed or loss of control. Remember: any excessive pull on the MAESTRO’s handle can cause a loss of control. To secure the rope against possible loss of control, attach an ASAP with ASAP’SORBER AXESS or…

The following tests were carried out in laboratories, with new devices and new ropes certified to current standards. Test results are given for information purposes only: they may be different with devices and/or ropes that are worn from use, or with other rope types or models. STATIC TESTS Slow-pull test…

The MAESTRO combines the abilities of a progress-capture pulley and a descender for effective hauling, releasing and lowering of the load. The AUTO-LOCK system locks the load automatically and returns the handle to the stop position.   Let’s start with a Petzl Maestro Overview! 1. Working principle The MAESTRO uses…

MAESTRO and I’D allow for efficient hauling, releasing the lock at any time and a controlled lower of the load. The two devices have different ergonomics and different specifications (working load and efficiency). Hauling The MAESTRO’s efficiency enables effective use of simple pulley systems. If a complex pulley system is…

A belay system must stop a falling load in case the work system breaks or fails.   The belay rope must ” follow ” the load, to avoid creating any slack that would increase the fall distance if the work rope fails. Belaying a hauling operation When hauling, belaying poses…

In certain cases of extreme urgency requiring a very rapid response, the rescuer can access the victim by descending on one rope. Once the emergency has been addressed, upward evacuation can be done at a “normal” level of safety with two ropes.   Precautions prior to descent: Make sure to…
