MAESTRO S

The PETZL MAESTRO high performance pulley is combined with a Self-locking Brake/Descender function.

It therefore allows, in a lifting or pulling system, to avoid the friction caused by a conventional descender by offering all the advantages of an excellent pulley associated with all the advantages of a self-locking descender.

The PETZL MAESTRO is a unique product at this price to achieve this function.

PETZL MAESTRO S and MAESTRO L Pulleys/Descenders are designed for lifting operations without loss of efficiency and GRIMP type Rope Access rescue.

They facilitate the handling of heavy loads, both downhill and hoist, and can be used both as a main system and as a back-up.
This versatility allows rescuers to adapt to all configurations that can be encountered in the place of intervention.

Advantages:

 * The integrated pulley-blocker, equipped with a very large diameter sheave on sealed ball bearings, ensures excellent hoisting performance.
* The unidirectional sheave turns freely in one direction but locks in the other direction to switch to descending mode.
* The AUTO-LOCK system automatically locks the rope on descent.
* Once locked, the rope can still be pulled without having to touch the handle.
* The ergonomic handle and the integrated additional brake make it easy to control the descent.
* The transition from the descent position to the hoist position is immediate, without having to transfer the load.
* This allows to be very efficient in the hauling and accurate in positions.
* The MAESTRO S descender is compatible with ropes from 10.5 to 11.5 mm and allows the handling of loads up to 250 kg.

 * The installation and extraction of the rope is quick and easy thanks to the guide and markings on the product.
* The handle, facing down, is set for natural use when the device is in the up position.
* A complementary friction groove allows you to better control your efforts and load by adding an extra friction ride.
* The new faceted V-groove sheave provides both good friction grip on the rope while ensuring a long service life.
* A becket in the lower part allows the return of rope during the composition of mechanical advantages.
* The ventilation fins and the size of the sheave allow to diffuse the heat for long descents.
* The classic operation of the handle, as on an I'D or a RIG, allow a good dosage and an optimal grip.
* The handle pierced with a hole, allows to make a small pull cord to control the descent at a distance.

Technical Rescue - Rope Access Resue - GRIMP:

Technical rescue or GRIMP teams respond when the situation is especially difficult and requires significant resources to be deployed.
They operate in any terrain. They have complete mastery of all progression and belay techniques on rope.
When the terrain allows, downward evacuation is preferred because of the gravity-assist.
But when it is necessary, upward evacuation is a team effort that requires perfect coordination by everyone involved.
It demands techniques which are sometimes particularly complex: raising systems, mechanical advantage, creating a hauling system using lightweight pulleys, counterweight techniques, etc.
In these situations, the PETZL MAESTRO pulley offers incomparable advantages in terms of ease and speed.

These Descenders/Pulleys provide the necessary versatility during technical rescue operations: descent, hoisting, handling of heavy loads, use in main system or belay-safety system.
