The Z2R is a multi-functional device which combines the functionality of an electrically assisted ascender with that of a pulley, and descender into one device.
A powerful drill is needed to operate the Z2R as ascender. The drill requires at least 50 Nm, however AWAH suggests 120 Nm for optimal operation. Brushless drills are required as they don’t build up heat as quickly. Additionally the drill’s battery has an effect on it’s performance, therefore batteries with more cells are better. AWAH states that a 5.0Ah battery is just enough, but an 8.0Ah battery is ideal. We strongly suggest to use a high quality brand drill with min. 18V battery for frequent use and/or long ascending distances under high load. We’ve used the Makita XPH14Z 18V LXT successfully for long and high load operation
-Z2R is designed to work with rope diameters ranging from 9-11mm. It works best with very stiff and static ropes. Normal EN 1891 ropes do not typically work well, because the ropes are too flexible. EN 1891A ropes work much better.
-The Z2R input shaft interface uses an 8mm (5/16") hexagonal bit. One is included with the Z2R. The length of the bits should be such that the electric drill and Z2R are as close as possible without making contact. If they are too long it may cause the device to shake under power.
-During AWAH's tests, the Z2R ran for 300,000 feet with a safe margin, however this was not performed under load. The nominal lifespan of the Z2R is 60,000 feet. Although there is a safety margin in the design, a backup system is still required as the ratchet system located inside the casing cannot be inspected.
-The maximum load for the Z2R is 440 pounds and it has a gear ratio of 100:12. The Z2R is designed specifically for rescue, with the ability to lift more weight and a becket for easier pulley system rigging.
