Abstract
A carriage for the transport and installation of heavy doors and other construction panels includes a door-holding frame that is pivotally attached to a wheeled chassis. Independent drive mechanisms provide accurate control over the elevation, tilt, and roll of a door panel held by the frame, and effect a precisely controlled, lateral movement of the panel relative to the frame.
Claims17
A carriage for a construction panel comprising:
- a chassis having a front end and a rear end;
- a plurality of casters supporting said chassis;
- a planar frame pivotally connected to said chassis at the front end thereof, said frame having a bottom sill member arranged to engage and support one edge of a construction panel;
- means for securing said panel to the frame at a location spaced apart from and above said sill member;
- means for coupling the sill member to said frame so that the sill member and the panel supported thereon are laterally movable relative to said frame in a direction parallel to the plane of the frame;
- and
- a diagonal member extending from the rear of the chassis to a location on said frame above said sill, the length of said member being adjustable between at least two positions, one of said positions fixing the frame and a panel secured thereto in an essentially vertical installation attitude, and another of said positions fixing said frame and panel in a transport attitude wherein said frame and panel are tilted backwardly over the chassis to allow passage of the carriage and panel through an opening.

A carriage for a construction panel comprising:
- a chassis having a front end and a rear end and having means for defining a multi-point rolling support;
- a planar frame pivotally connected to said chassis at the front end thereof, said frame having a bottom sill member arranged to engage and support one edge of a construction panel;
- means for securing said panel to the frame at a location spaced apart from and above said sill member;
- and
- a diagonal member extending from the rear of the chassis to a location on said frame above said sill, the length of said member being adjustable between at least two positions, one of said positions fixing the frame and a panel secured thereto in an essentially vertical installation attitude, and another of said positions fixing said frame and panel in a transport attitude wherein said frame and panel are tilted backwardly over the chassis to allow passage of the carriage and panel through an opening, said diagonal member including two articulated segments that are arranged to fold and, when folded, to allow said frame to recline above and generally parallel to said chassis.
