International Classification:
E04G 21/14, B65G 47/91, B25J 9/10
US Classification:
414 11, 414627, 414590, 414783, 901 40
Abstract:
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.
