    • A material transport system and method of use is disclosed herein. The system includes a base assembly having an adjustable width, a material support platform hingedly attached to the base assembly, the platform supported angularly above the base assembly by at least two support tubes hingedly attached to the base assembly, a left pair and a right pair of rail guides aligned along the length of the base assembly, the rails removably attached to the underside of the base assembly, and a left pair and a right pair of wheels axially mounted between each rail guide pair, the bottom edges of the rail guides extending past the edges of the wheels, the system characterized in that the rail guides and wheels enable the transport system to be pulled along the rails of a ladder by wire, rope, or like component attached to the transport system.

    • A ladder bridge apparatus for use in connecting two ladder sections is disclosed herein. The ladder bridge apparatus, in its simplest form, includes an adjustable center stabilizer bar connecting outer rail bridge assemblies. The rail bridge assemblies are directly connected to the adjacent ladder sections. The ladder bridge apparatus can be utilized in conjunction with a material transport device to transport materials over the rails of a first ladder section and onto and across the ladder bridge apparatus to a second ladder section.
    • 本文公开了一种用于连接两个梯形部分的梯形桥式装置。 梯形桥装置以其最简单的形式包括连接外轨道桥接组件的可调节的中心稳定杆。 轨道桥组件直接连接到相邻的梯子部分。 梯形桥式装置可以与材料输送装置一起使用,以将材料运输到第一梯形部分的轨道上并跨越梯形桥式装置并跨越梯形桥式装置运送到第二梯级部分。

    • A ladder ridge anchor device and system incorporating new and improved mechanisms are disclosed herein for attaching a ladder to a roof ridge anchor to secure a ladder over the roof ridge of a building. These improvements also allow the user to easily adjust the position of the ladder relative to the roof ridge anchor to facilitate work on and access to the roof or other building areas. Stabilizing components help prevent lateral movement of the ladder with respect to the attached ridge anchor and extension components elevate the ladder and roof ridge anchor off the surface of the roof.
    • 本文公开了一种结合新的和改进的机构的梯脊锚定装置和系统,用于将梯子附接到屋顶脊锚固件以将梯子固定在建筑物的屋脊上。 这些改进还允许使用者容易地调整梯子相对于屋顶墩锚的位置,以便于对屋顶或其他建筑物区域的工作和接近。 稳定部件有助于防止梯子相对于附接的脊锚固件的横向运动,并且延伸部件将梯子和屋顶脊锚定件从屋顶的表面上升高。
