The descent and rescue device, UZO 9, conforms to the standard EN 341:2011.

The device is operated manually and conforms to the requirements for the B class equipment.

UZO 9 is fitted with a fixed 11 mm static rope [1].

The device’s core is a fixed metal plate placed between two halves of its housing. The device tapers towards the bottom, where the attachment point for an EN362 conforming connector is located [2].

Inside the device a system of rollers guides the rope and a rotating cam that changes position to lock and unlock the rope by pressing it against a fixed, unmoving contact part. The textile rope enters the device from above, runs downwards, circling the cam from the left-hand side, and then upwards between the cam and the contact. It exits the device housing towards the handle for descent control. KEY FEATURES

Other mechanical parts are situated on the other side of the metal plate, under the back of the housing – like a gear that coordinates the movement of the handle [3] with the rotating movement of the cam.

To replace the rope, it is necessary to unscrew and open the front part of the housing [4].
