Boarding ladder of transport vehicle

The utility model provides a boarding ladder of a transport vehicle. The boarding ladder of the transport vehicle comprises a weight-reduced fish-shaped beam, a non-weight-reduced fish-shaped beam, reinforcing ribs, angle steel, supplementary plates, longitudinal beam sleeves, pulleys, bolts and supports. The boarding ladder and the vehicle body are fixedly connected through the top end of the fish-shaped beam in a bolt mode, and safety and reliability are achieved; the fish-shaped beam structure can increase rigidity and strength; the angle steel is welded on the transportation surface, so that personnel or goods can be prevented from slipping off; the U-shaped structure formed by the three fish-shaped beams can prevent personnel or goods from falling off from the edge in the bearing process, and the limiting effect is achieved; the boarding ladder can be conveniently and quickly assembled and disassembled through the pulleys installed on the side face, and wartime troops can quickly maneuver conveniently. 本
