Abstract
A constructional herringbone ladder is disclosed. The constructional herringbone ladder comprises a first ladder frame and a second ladder frame which are hinged. Both the first ladder frame and the second ladder frame comprise straight bars, ladder bars and ladder feet. Object placing plates are connected between the first ladder frame and the second ladder frame through a screw joint manner. A hinge is disposed between the object placing plates. An object passing plate is disposed at the upper end of the first ladder frame. The lower end of the object passing plate is fixed to a pulley block. The lower end of the pulley block is provided with a hook. An objected needed for work is placed on the object placing plate and is lifted to the top of the ladder through the pulley block. By combination of the object placing plate and the hinge, the maximum span of the ladder is limited. The ladder is simple and reasonable in structure and convenient to use. Objects are not needed to be lifted up and down the ladder so that the working intensity is reduced and the ladder using is safer.
