Manufactured from steel with a baked enamel finish, the RGR7 has a 50cm diameter handle turn. With a full one handle turn will release approximately 48mm of cable. This unit has many applications such as confined space entry, manholes and chemical vessels. The operative can ascend / descend to safety almost immediately. As most rescue systems lower the casualty, the RGR7 can raise the operative to safe area, if the area below is unsuitable. The RGR7 can be fitted to the RGR1 tripod for use in confined space access when ladders or foot irons are not available or deemed unsuitable.
