Prestress carbon fiber aerial ladder truck cantilever crane
A prestress carbon fiber aerial ladder truck cantilever crane mainly comprises vertical ladder columns, ladder steps, struts and lateral oblique beams, wherein the vertical ladder columns are connected with the lateral oblique beams; the lateral oblique beams are connected with the struts; the struts have the load-bearing effect; the left strut and the right strut are connected with each other by the ladder steps; and a worker can walk on the cantilever crane through the ladder steps. The structural style of cross sections of the struts is improved, carbon fiber materials are pretreated so that the carbon fiber materials have the prestress effect, and then the prestressed carbon fiber materials are connected with the struts of the cantilever crane. The invention provides an aerial ladder truck firefighting cantilever crane structure, the cross sections of the struts of the cantilever crane have novel C-shaped structures, and two sections of the cantilever crane are combined in an inserted mode. In addition, the carbon fiber materials are tensioned in advance, the cross sections of the struts of the cantilever crane have the novel C-shaped structures, and inner lower sides of the struts and the prestressed carbon fiber materials are anchored. The novel cantilever crane is subjected to a reverse prestress effect when not working; stress and deformation conditions of the cantilever crane can be improved effectively when the cantilever crane works, and therefore, the prestress carbon fiber aerial ladder truck cantilever crane is high in efficiency, good in performance and high in safety.
