Descender with integrated progress-capture pulley for loads up to 250 kg, compatible with 10.5 to 11.5 mm ropes

MAESTRO S is a descender designed for technical rescue operations. It facilitates manipulation of heavy loads, for lowering or hauling, and may be used in both the primary system or in a back-up belay. This versatility allows rescuers to adapt to any situation they may encounter on the rescue scene. The ergonomic handle and integrated brake allow for comfortably controlled descent. Shifting from lowering position to hauling position is immediate, without the need to transfer the load. The integrated progress-capture pulley has a large diameter sheave mounted on sealed ball bearings, ensuring excellent hauling efficiency. The AUTO-LOCK system automatically locks the rope when the handle is not in use. Once locked, the rope can be taken up without having to manipulate the handle. The MAESTRO S descender is compatible with 10.5 to 11.5 mm ropes and allows handling of loads up to 250 kg.

Description

  • Great versatility, ideal for technical rescue:
    - locking system with integrated progress-capture pulley allows the same device to be used for descent and hauling
    - can be used in both a single or twin primary system and in a back-up belay (more information on this technique in the product’s instructions for use and in technical tips at www.petzl.com)
    - lower connection point can be used to create different types of hauling systems
    - hole in the handle for installation of a distance control cord
  • Easy to use:
    - easy rope installation, thanks to the markings on the device
    - ergonomic handle allows the rope to be released progressively and enables comfortable control of the descent
    - immediate shift from lowering position to hauling position without having to transfer the load
    - AUTO-LOCK system allows the rope to be blocked automatically when the handle is not in use. Once locked, the rope can be taken up without having to manipulate the handle.
  • Efficient for handling heavy loads:
    - integrated progress-capture pulley with very large diameter sheave mounted on sealed ball bearings; rotates in only one direction for excellent hauling efficiency
    - sheave is faceted, creating additional friction zones for the rope and thus additional braking on descents
    - integrated brake on the device to adjust the friction based on the load and the rope diameter
    - handling of loads up to 250 kg
  • Rope compatibility: 10.5 to 11.5 mm diameter

I just got it changed about 30 min ago and the engine sounds like a little cat
Size: 5 L
My Audi factory setting says I should use VW 508.00. Somewhere online it says 5w-40. It's 82000 miles and I decided to give it a shot to go 0W-20 which is what VW508.00 is. I just got it changed about 30 min ago and the engine sounds like a little cat. The gas pedal feel is very smooth, there's definitely less resistance when pushing forward. In Sports mode driving, the engine is not as loud and the lag or drag is noticeably less. And when it hits 100k, I will do a engine flush to see if I can get further improvements. So far, I really love Liqui Moly. I used to use it on my S500 and it was very smooth. A little more money goes a long way! Don't settle for less for your German cars. Update: I just did another 1000 miles in a week to Vegas and back. The fuel economy improved about 20%. The power increase is amazing. I could notice when I am going fast, the sustained speed at high speed is easy and continuous, It doesn't just hit a snag when your foot is off the pedal. And the engine is definitely a lot quieter and smoother. I am amazed at the overall improvement after using this oil. No other oil will do from now on.

Do it!
Size: 5 L
Use it in a 14 Sierra. Get about 7500 miles an oil change going off the oil life monitor but I drive rough and the trucks modded. Pricier than others, but I feel it’s worth it. Truck runs smoother than what was in it.
