Abstract
An apparatus for transporting and unloading large loads of wallboard is disclosed. A base frame with wheels allows the apparatus to be moved over a surface. An upper frame is positioned above the base frame. The upper frame includes a curved member that extends convexly away from the upper frame. Means are provided between said base frame and said curved member for allowing said upper frame to move relative to said base frame. A lock means selectively prevents said curved member and upper frame from moving relative to said base frame.
Claims6
An apparatus for transporting a load through narrow passageways and unloading the load at a desired location, comprising:
- a base frame,
- wheel means connected to said base frame for allowing said base frame to be moved,
- an upper frame positioned above said base frame, said upper frame having a lower load receiving portion normally positioned substantially parallel to said base frame and an unloading section projecting substantially perpendicular upward from said load receiving portion,
- said upper frame having curved members extending convexly away from said unloading section of said upper frame,
- hinge means between said curved members and said unloading section,
- means between said base frame and said curved members for allowing said upper frame to move relative to said base frame, and
- lock means for selectively preventing said upper frame from moving relative to said base frame and for selectively allowing said upper frame to move relative to said base frame and unload said load.
An apparatus for transporting a load of building materials and depositing said load of building materials at a desired location, comprising:
- a base frame;
- wheels on said base frame for allowing said base frame to traverse a surface;
- an upper frame for receiving said load positioned above said base frame, said upper frame having a lower load receiving portion normally positioned substantially parallel to said base frame and an unloading section projecting substantially perpendicular upward from said load receiving portion;
- a pair of curved members connected to said upper frame, said curved members extending convexly away from said upper frame;
- hinge means between said curved members and said unloading section;
- rollers on said base frame that contact said curved members to allow said upper frame and load to be rotated relative to said base frame and deposit said load at the desired location;
- and
- a lock for selectively locking said upper frame to said base frame to prevent the upper frame from rotating relative to said base frame and for selectively allowing said upper frame to move relative to said base frame and unload said load.
