An apparatus for cleaning bridges or other elevated structures includes a base element and an upper element that is vertically movable with respect to the base element. The upper element supports workmen for cleaning the structure. The floor of the upper element is made of a grid or grating such that debris falls through the floor and is collected in the base element. The base forms a collection hopper and includes a conveyor running along the center for carrying the debris to one end of the base for discharge of the debris. Hydraulic cylinders control the vertical position of the upper element so that the upper element may be placed at the desired elevation. The base element includes wheels and a hitch for allowing the apparatus to be towed on the highway to the structure to be cleaned or repaired.
Apparatus for maintenance of an elevated structure comprising a transportable base element and a vertically movable upper element mounted to said base element for controllable vertical motion with respect to said base element, wherein said base element comprises hopper means for collecting debris and conveyor means for carrying debris collected by said hopper means along said base element and for discharging said debris, and said upper element comprises platform means for supporting workers and allowing said debris to pass directly to said hopper means.
A method for cleaning an elevated structure comprising the steps of providing a portable apparatus comprising a base element having a hopper for collecting debris and an upper element that supports workers, allows said debris to pass directly to said hopper, and is vertically adjustable with respect to said base element, moving said apparatus to a horizontal location near said structure, raising said upper element to a vertical location adjacent said structure, cleaning said structure, and allowing debris resulting from said cleaning to fall through said upper element directly to said hopper in said base element.
A trailer for use in cleaning an elevated structure comprising:
