Abstract: A device for use in lifting, transporting and installing sheet material has a base, wheels on which the base is supported, a mast that extends upwardly from the base, a carriage that is in engagement with the mast, a supporting head that is mounted to the carriage, and a lifting mechanism to provide support to the carriage in the longitudinal direction of the mast. The wheels include rear wheels that are connected to the rear of the base in a manner that permits steering of the device during movement across a surface, and a front wheel set that is connected to the front of the base. The front wheel set includes a wheel to each side of the device, and the wheels of the front wheel set are rotatable about a common axis. The connection of the mast to the base is such that the mast is rotatable relative to the base about a rotational axis. The device further has an actuator that is operable to change the angular position of the mast relative to the base.

Abstract: A device for lifting and transporting sheet material includes a base portion; wheels on which the base portion is supported; a mast that extends upwardly from the base portion; a boom that extends from a first end outwardly from the mast to a second end; a supporting head that is configured to support sheet material; and a pivot coupling at the second end of the boom. The pivot coupling is arranged to couple the supporting head to the boom, and enable the supporting head to be rotated about a pivot axis between a first position in which sheet material supported by the supporting head is in a generally transverse orientation relative to the boom, and a second position in which the angle between sheet material supported by the supporting head and the boom is reduced.

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.

Abstract: A device for handling glass or other sheet material is in the form of a wheeled trolley capable of manual manipulation and having a support shaft which extends upright in use of the trolley. Two or more vacuum grips are mounted on the shaft for movement into selected positions along the shaft.
