A panel installation apparatus is cooperable with an aerial work platform of a lift vehicle for installation of panels on a surface. The apparatus includes a trolley movable on at least one rail supported by the aerial work platform between a displaced position spaced from the surface and engaged position adjacent the surface. The trolley is sized to support a panel to be installed. At least one mounting unit is fixed to the aerial work platform via a mounting unit frame and pivotable between a receiving position adjacent the trolley in the engaged position and an installing position adjacent the surface. The mounting unit includes at least one fixing unit selectively attachable to the panel. With the panel delivered to the mounting unit, the mounting unit can be pivoted and secured to the panel via the fixing unit, and the panel can be subsequently pivoted adjacent the surface for installation.

Panel installation apparatus and method

An aerial work platform apparatus includes a shiftable counterweight which shifts in response to movement of the boom in order to maintain optimum balance of the apparatus during movement of the boom and platform. The counterweight shifts towards and away from the front of the apparatus, and also in a vertical direction. Several constructions for shifting the counterweight are disclosed.
