摘要： A brake/ballast assembly for a movable structure. The brake/ballast assembly includes a movable brake/ballast plate movable between a movable brake/ballast plate first position in which the movable brake/ballast plate is positioned proximate a fixed member and a movable brake/ballast plate second position in which the movable brake/ballast plate is spaced from the fixed member. An engagement member is connected to the movable brake/ballast plate. The engagement member is movable between an engagement member first position and an engagement member second position. When the engagement member is in the engagement member first position, the movable brake/ballast plate is provided in the movable brake/ballast plate first position allowing the movable structure to be moved along a surface. When the engagement member is in the engagement member second position, the movable brake/ballast plate is provided in the movable brake/ballast plate second position preventing the movable structure from moving relative to the surface.

摘要： A base for use with scaffolding. The base includes side support members and cross members. The side support members have scaffold receiving members provided at ends thereof. The cross members extend between the side support members and are rotatably mounted to the side support members. Wheels are mounted to the cross members. As the cross members are rotated from a first position to a second position, the wheels are moved from an initial position in which the wheels are spaced from a ground or floor surface to a second position in which the wheels are positioned in engagement with the ground or floor surface.

摘要： A lifeguard observation station having a support structure for allowing a lifeguard to monitor a pool and swimmers or bathers therein. The lifeguard observation station includes a platform which is configured to accommodate the lifeguard. The platform member has a first edge, with at least a portion of the first edge of the platform member and a portion of the platform member adjacent the first edge being configured to extend to or beyond a pool edge of the pool. When positioned on the portion of the platform member adjacent the first edge, the lifeguard is positioned at the edge of the water or over the water in the pool to provide the lifeguard an unimpaired line-of-sight to the swimmers or bathers in the pool.
