Abstract
A material handling machine including a power driven, steerable chassis which supports a vertical mast and a pivotally attached telescoping boom having a material carrier rack, including a device for securing material to the rack. The mast is supported on a base that is selectively movable in a transverse direction with respect to the chassis. The end of the telescoping boom carries a hydraulic orbiting motor that provides for selective rotation of the rack in either a clockwise or counter-clockwise direction. A pair of hydraulic cylinders, together with a universal joint, are attached to the rack and provide for pivoting or tilting of the rack about both the vertical and horizontal axes.
Claims3
A flat panel handling machine for use in transporting and positioning large flat sheets of material, the machine comprising:
- a chassis;
- ground engaging wheels attached to and supporting said chassis;
- means for driving said ground engaging wheels;
- means for steering said chassis;
- a mast attached to and extending upwardly from said chassis;
- wherein, said mast is mounted on a base having rollers attached thereto, and said rollers are disposed to be received in a track attached to said chassis;
- means for selectively moving said mast in a transverse direction on said chassis;
- including a hydraulic mast base cylinder operably attached to and interconnecting said mast and said chassis;
- and means for controlling the flow of hydraulic fluid to said mast base cylinder;
- a boom pivotally attached to said mast and extending outwardly therefrom;
- means for selectively pivoting said boom with respect to said mast;
- including a hydraulic boom pivoting cylinder attached to and interconnecting said mast and said boom, and means for controlling the flow of hydraulic fluid to said boom pivoting cylinder;
- means for selectively extending and retracting said boom;
- including a first boom section disposed to telescopically receive a second boom section and a hydraulic boom telescoping cylinder attached to and interconnecting said first and second boom sections;
- and means for controlling the flow of hydraulic fluid to said boom telescoping cylinder;
- a shaft having one end attached to an end of said boom and extending outwardly therefrom;
- a material carrying rack attached to the other end of said shaft;
- means for selectively rotating said rack;
- including a hydraulic orbiting boom motor operably attached to and interconnecting said second boom section and one end of said shaft;
- and means for controlling the flow of hydraulic fluid to said boom motor;
- means for securing material to said rack;
- including vacuum cups attached to said rack;
- and a vacuum source for applying a vacuum on said cups;
- and,
- means for pivoting said rack about its vertical and horizontal axes;
- including, a universal joint attached to and interconnecting the other end of said shaft and said rack;
- a first hydraulic rack cylinder attached to and interconnecting said shaft and said rack;
- a second hydraulic rack cylinder disposed normal to said first rack cylinder and attached to and interconnecting said shaft and said rack;
- and, means for controlling the flow of hydraulic fluid to said first and second rack cylinders.
