MAESTRO® L
Descender with integrated progress-capture pulley for loads up to 280 kg, compatible with 12.5 to 13 mm ropes
Tower rescue: skate block with REEVE
REEVE allows an efficient and clean setup of all the necessary equipment.
Using pulleys with small-diameter rope or cord.
As part of their certification as PPE, Petzl pulleys are compatible with ropes greater than 7 mm in diameter. The use of thinner cords may be possible.
Using the TWIN RELEASE for a 3:1 Haul System
TWIN RELEASE was designed to be used in a 4:1 system. In certain situations, hauling with a 3:1 system can be advantageous, even though it offers a lower mechanical advantage.
Descending With Additional Braking
Ease of descent depends on the wear on the device, the rope that is used, and the load. Additional braking can help you avoid being surprised by the descent speed (for example on a new, thin rope). It can also help provide a more controlled and comfortable descent.
Remote control of the MAESTRO handle with a cord
The MAESTRO handle has a small hole for attaching a cord (e.g. AIRLINE cord).
How to calculate mechanical advantage
A mechanical advantage haul system reduces the effort required to raise a load. The mechanical advantage obtained is based on the pulley effect.
Primary uses of the RIG
The RIG is a self-braking belay / rappel device that can be used on either the harness or the anchor.
