## 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.

a first plate fixedly attached to the boom adjacent the pivot coupling, the first plate including two spaced apart holes;
a second plate movable with the pivot coupling about the pivot axis; and
a drop pin that moves with second plate, wherein when the supporting head is in the first position, the drop pin can be passed through a hole in the first plate to retain the supporting head in the first position.

### Claim 2 (depends on 1)

A device according to claim 1, wherein the pivot coupling includes a pin attached to one of the boom and the supporting head, and a tube attached to the other of the supporting head and the boom, and wherein the tube is rotatably supported on the pin.

### Claim 3 (depends on 1)

A device according to claim 1, wherein the pivot coupling includes:
a pair of brackets that each have one or more apertures, each bracket mounted to a respective one of the boom and the supporting head; and
a pin, wherein the apertures in the brackets are aligned and the pin passes through the aligned brackets to couple the brackets to one another.

### Claim 4 (depends on 1)

A device according to claim 1, wherein the supporting head includes an inner portion attached to the pivot coupling, an outer portion including one or more elements that support the sheet material, and a rotary coupling that couples the inner and outer portions such that the outer portion is rotatable relative to the inner portion about an axis that is non-parallel to the pivot axis.

### Claim 5 (depends on 4)

A device according to claim 4, further comprising a second retaining mechanism such that the outer portion can be releasably retained in one or more rotational positions relative to the inner portion.

### Claim 6 (depends on 1)
