A land vehicle, is provided with a mobile work platform assembly with a platform mounted to the land vehicle, sized to receive an operator thereupon. A frame extends from the platform. A positioner assembly includes a guide mounted on the frame of the mobile work platform assembly. A carriage is provided on the guide for translation along the guide. Hardware is provided on the carriage to support a workpiece upon the carriage external of a perimeter of the frame. The carriage includes a brake assembly to position the carriage at various positions along the guide.

There is provided herein a lifting and inversion bar especially configured for repositioning cable spools which typically comprise fragile end stop annuli. The present cable spool lifting and inversion bar is configured for repositioning a cable spool comprising a length and radius between horizontal (that is wherein the axis of the cable spool is horizontal) and vertical (that is wherein the axis of the cable spools vertical) orientations. The inversion bar comprises a straight frame and an orthogonal shaft bisecting the frame into long and short ends. Furthermore, for the vertical orientation, the spool is able to freely rests atop the frame without additional support which negates the requirement for horizontal spacers as does the prior art. In this way, the spool may be conveniently lifted from the inversion by using a forklift, a convenient procedure not made possible by the prior art arrangements.

A balanced cantilevered feeding apparatus for coupling with a jib, and a complementary method for its operation, configured to facilitate depositing and removing of a load through an opening in a building. The apparatus includes two spaced apart upright hoisting assemblies disposed on the jib, and a fly beam hoisted, balanced, and selectively positioned along a lateral axis by the two hoisting assemblies. A load securing member is mounted on a cantilevered extension portion of the fly beam, wherein the member extends beyond one of the two hoisting assemblies toward the building, and a counterweight is connected to the fly beam in the vicinity of another of the two hoisting assemblies.

A structure installation system which maintains one or more walls in a desired position and orientation during installation of the one or more walls. The structure installation system generally includes a vehicle which is adapted to traverse a ground surface. The vehicle includes an arm having an arm coupler to which a support is connected. One or more walls adapted to be installed in the ground surface may be removably connected to the support, such as by securing the walls to adjustable hangers that are removably connected to the support. By adjusting the positioning of the hangers, the orientation and position of the walls may be adjusted. Once put in position, the vehicle and support will retain the walls in the desired position and orientation while concrete is poured and allowed to cure to form a unitary structure such as a bollard wall.
