Claims20
An apparatus for servicing a structure, comprising:
- a frame for assembly or arrangement around the structure, the frame including upper and lower supports provided at axial ends of the frame and a middle support provided between said opposite ends of the frame, connected together by vertically extending struts to form a generally cylindrical structure;
- at least one pair of first and second arms pivotally attached at proximal ends thereof to the middle support;
- and
- at least one pair of first and second rotating members, attached to distal ends of the respective first and second arms, for contact with the structure;
- the first and second arms extending in axially opposite directions and being pivotable so as to move the corresponding first and second rotating members towards or away from the structure;
- wherein at least one of the first and second arms is arranged to pass between adjacent ones of the struts such that the corresponding first or second rotating member is able to contact the structure.
