ABSTRACT:
A sheet handling device for handling large sheets of glass or other sheet material, the device comprising a wheeled trolley having an upright support shaft (2), a carriage movable along the shaft (2) into a selected position, and at least two vacuum grips mounted to the carriage to engage the sheet at positions displaced in the height direction of the sheet. In another embodiment the carriage is movable by operation of a winch. The trolley is normally used in conjunction with a second like trolley so that the vacuum grips of the two trolleys engage the sheet at spaced positions along the length of the sheet. The two trolleys are preferably interconnected by releasable bracing which can be stored on the trolleys for ease of transportation. In a further embodiment there is also disclosed a glass installation guide to facilitate guidance of a large glass sheet into a frame during installation.
