摘要： A transportable and erectable stairtower having a removable/slidable wheel carriage and a removable installation section arranged for transporting and erecting the stairtower. The stairtower has vertical column members and lateral members defining levels of the stairtower. Removable staircases extend between alternate levels of lateral members. A platform landing is formed at the intersection of first and second stair segments of the staircase. Removable ramps may be connected to the stairtower above, below, and at a position corresponding to the platform landings. A safety device in the form of catch pans, gutters, and leaders may be provided to protect workers by collecting debris and rainwater. A transporting vehicle may be connected to the installation section to transport the stairtower to a desired location. A lifting vehicle may be used to lift the stairtower from a horizontal to a vertical orientation.

摘要： The present invention relates generally to a modular ramp (10) formed of prefabricated components. The modular ramp (10) includes a raked floor (12), elongate members in the form of floor pillars (14) and (15), and hand rails (16). The raked floor (12) is formed of a number prefabricated floor segments, an example of which are prefabricated floor panels (32) which extend between adjacent prefabricated floor bearers (34). The floor bearers (34) are supported by the floor pillars (14) and (15). The prefabricated floor bearers (34) have sleeves (56) and 58 attached at each end for respective receipt of the floor pillars (14) and (15). The pillars (14) and (15) are thus arranged for longitudinal movement relative to the sleeves such as (56) and locating pins (83) retain the pillars (14) or (15) relative to the sleeve (56).

摘要： The present invention is an easy to use device that attaches to a beam. The device may be used as a step for a user to stand on and attain elevation. The device may be used in combination to form a scaffold or a platform. The device is a tool having an upper surface with tapered ribs located on the back edge of the upper surface, a vertical member, and a collar. When the tool is placed around a beam and downward force applied to the tool, the ribs engage a first side of the beam and the collar engages the opposite side of the beam forming a lever. The tool is locked in place and the user is free to stand on it for support and elevation.
