2. Application
The MRG9 easy and the MRG9 easy+ rescue device for descending and lifting are rescue devices
by means of which one person or two persons simultaneously or several persons one after the
other are able to vertical descend from a higher to a lower level at limited velocity. In addition, a
person can be lifted vertically from a lower to a higher level by a rescuer or a rescuer can approach
a casualty, collect that person and descend with the casualty.
The equipment may only be used within the limits defined in this user manual and for its intended
use. The MRG9 easy and the MRG9 easy+ rescue device for descending and lifting may only be
used as rescue system and not as fall arrest system. The device can be used in vertical, horizontal
and inclined position. The position depends on the particular use.
Vertical position : device is hanging vertically on an anchor point.
