ABSTRACT:
A cylindrical member maintenance device is comprised of a housing comprised of two hinged halves for being closed around a cylindrical member, such as a stranded steel cable. A rotary helical brush assembly and a rotary longitudinal brush assembly are positioned in the housing and rotatable about an axis of the housing. Each rotary brush assembly is comprised of coaxial split rings with rotary cylindrical wire brushes connected in between and which are independently rotatable about their own axes. Nozzles are positioned on the inside of the housing for applying a cleaning fluid or paint to the cylindrical member. Apertures in the housing are for connecting to a suction device for removing debris, cleaning fluid, and paint to avoid contaminating the environment. Loops on the housing are for attaching to cables for moving the housing along the cylindrical member.
