Abstract
Abstract A handling apparatus for lifting, transporting, tilting and positioning heavy workpieces, such as plate glass, or other large, cumbersome objects which require accurate placement and smooth, precision handling. The apparatus includes a lift vehicle having an elevatable member on which are mounted a plurality of hydraulically controlled interacting, extendible struts for positioning a workpiece holding frame, whereby the apparatus can be controlled by a single operator.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
Apparatus for handling a flat sheetlike generally vertical workpiece comprising, in combination: a. support means for attachment to the workpiece, b. first rotatable means mounting said support means for rotation thereof and of the workpiece in its own plane about a generally horizontal axis perpendicular to the plane of the workpiece, c. maneuvering means connected to said support means for selectively moving said support means and a workpiece vertically and pivotally; said maneuvering means including a frame having a pair of vertically spaced selectively extendable and retractable parallel hydraulic piston and cylinder members, each piston and cylinder member being pivotally connected at one and to the frame and at its opposite end to the support means, said members being actuatable simultaneously or separately, d. second rotatable means mounting said maneuvering means for rotation about a generally vertical axis, e. and means for moving said maneuvering means relative to said second rotatable means and generally parallel to the plane of the workpiece.
Claim 2
Dependent Claim
161 words
Apparatus for handling a flat sheetlike generally vertical workpiece comprising, in combination: a. support means for attachment to the workpiece, b. first rotatable means mounting said support means for rotation thereof and of the workpiece in its own plane about a generally horizontal axis perpendicular to the plane of the workpiece, c. maneuvering means connected to said support means for selectively moving said support means and a workpiece vertically and pivotally; said maneuvering means including a frame having a pair of vertically spaced selectively extendable and retractable parallel hydraulic piston and cylinder members, each piston and cylinder member being pivotally connected at one and to the frame and at its opposite end to the support means, said members being actuatable simultaneously or separately, d. second rotatable means mounting said maneuvering means for rotation about a generally vertical axis, e. and means for moving said maneuvering means relative to said second rotatable means and generally parallel to the plane of the workpiece.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 in which said first rotatable means comprises turntable means interconnecting said support means with said maneuvering means.
Claim 4
Dependent Claim
19 words
The apparatus of claim 2 which includes stop means for locking said turntable means at any angular position thereof.
Claim 5
Dependent Claim
49 words
The apparatus of claim 1 which includes linear guide rail means fixed to said second rotatable means, and linear slide means mounted on said guide rail means for movement therealong, and in which said moving means (e) comprises an extendable-retractable member interconnecting said guide rail means and slide means.
Claim 6
Dependent Claim
28 words
The apparatus of claim 1 which includes a generally horizontal platform; and in which said second rotatable means comprises turntable means interconnecting said platform with said maneuvering means.
Claim 7
Dependent Claim
30 words
The apparatus of claim 1 which includes means for vertically moving said support means and the workpiece over a larger range of elevations than that provided by said maneuvering means.
