An apparatus for manipulating assembly components into desired configurations and a method for using same, where the assembly component includes a first and second bore set at a first and second transverse angles, for receiving attaching members. The apparatus includes a pair of attaching members that engage the bores to extend toward each other, and a manipulating member securing the base portions of the attaching members to each other. The attaching members may include side struts that relieve side pressure on the bores and may also include internal air passageways. The manipulating member has a length that prevents the secured attaching members from disengaging from their bores, and provides a location for a moving device to indirectly connect to the assembly component. The moving device can move the assembly component in a different directions to achieve different configurations.

A walkway installation includes a walkway assembly which includes at least one tread module supported by a pair of spaced apart elongate supports which extend in the direction of the length of the walkway installation, the walkway installation additionally including a handrail assembly including a handrail which extends in the direction of the length of the walkway assembly and a plurality of spaced apart posts which each secure the handrail relative to the walkway assembly, the handrail assembly additionally including a first connector which secures a post to one side of the walkway assembly and the first connector having secured thereto a substantially inflexible transverse link which extends across the walkway assembly in a direction perpendicular to the length of the walkway installation, the transverse link extending to a second connector secured to the other side of the walkway.

A jaw crusher assembly comprising a jaw crushing apparatus and a service platform. The jaw crushing apparatus having first and second opposing jaws, each opposing jaw having a crushing face. The crushing faces opposing each other in an oblique relationship when the opposing jaws are in an at least partially opened state. The service platform provides at least two service configurations within the opposing jaws and being operable between a first service configuration and a second service configuration by rotation of the service platform.

A temporary step and support assembly includes two primary portions: an attachment member and a horizontal surface member. The attachment member preferably includes three sides for engaging a board or other fixed support, wherein the first side and the third side are disposed in parallel relation, and the second side is preferably angled upwardly from the first side to the third side. The horizontal support member, extends from the first side of the attachment member, and serves as a temporary step, so that a user may attach the temporary step and support assembly to a board or other fixed support for standing or climbing to reach a greater height in an upward direction. Optionally, the horizontal support member may be angularly adjustable with respect to the attachment member for use on angled fixed support studs, boards or framing.

A modular platform is provided and includes a platform having upper and lower surfaces. The modular platform further includes one or more propulsion units, mesh coverings, jack elements and a lock mechanism. The one or more propulsion units are embedded within the platform to generate upward thrust. The mesh coverings overlay each of the one or more propulsion units in the upper surface. The jack elements are coupled to the lower surface and support the platform above an underlying substrate. The lock mechanism connects the platform to a neighboring platform. A power storage unit is embedded in the platform and powers the one or more propulsion units, the jack elements and the lock mechanism. A control unit is embedded in the platform and controls operations of the one or more propulsion units, the jack elements and the lock mechanism.
