Abstract
Abstract To turn large pieces of goods 90* a mechanism is provided, which includes a platform hingedly connected to a base structure in such a manner that the upper face of the platform will be flush with the level of a spot upon which large pieces of goods to be turned 90* are brought. This spot may be a weighing machine or a part of a conveyor. The platform is provided with a telescopic pillar mounted perpendicurlarly thereto, which at its end remote from the platform is provided with an arm extending over the platform. Power operated means are provided, to swing the platform 90* in relation to the base structure, and to adjust the length of the telescopic pillar, respectively, to make the arm thereof fore a piece of goods placed on abovementioned spot towards the platform, when the latter has been brought to vertical position. Thereupon the platform may be swung back to horizontal position, while the pillar and the arm maintain the piece of goods locked upon the platform.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
178 words
A load handling mechanism for clamping large pieces of goods and turning them by 90*, comprising: a generally quadrilateral shaped platform disposed horizontally in flush with a floor level, the platform having hinge means on one side thereof to enable the platform to be turned about the hinged means into a substantially vertical position; a telescopic pillar secured perpendicularly to the platform at a side thereof remote from said one side having the hinge means; an arm and a clamping pressure plate attached thereto and extending substantially perpendicularly at a free end of said telescopic pillar in a manner as to extend over said platform, said arm including an adjustable mounting means therein so as to vary a distance of said clamping pressure plate from said pillar; a first poweroperated means to rotate the platform about said hinge means by substantially 90* in relation to a base structure; and a second power-operated means to adjust the length of the telescopic pillar to make said clamping pressure plate secure goods placed between said platform and the clamping pressure plate.
Claim 2
Dependent Claim
178 words
A load handling mechanism for clamping large pieces of goods and turning them by 90*, comprising: a generally quadrilateral shaped platform disposed horizontally in flush with a floor level, the platform having hinge means on one side thereof to enable the platform to be turned about the hinged means into a substantially vertical position; a telescopic pillar secured perpendicularly to the platform at a side thereof remote from said one side having the hinge means; an arm and a clamping pressure plate attached thereto and extending substantially perpendicularly at a free end of said telescopic pillar in a manner as to extend over said platform, said arm including an adjustable mounting means therein so as to vary a distance of said clamping pressure plate from said pillar; a first poweroperated means to rotate the platform about said hinge means by substantially 90* in relation to a base structure; and a second power-operated means to adjust the length of the telescopic pillar to make said clamping pressure plate secure goods placed between said platform and the clamping pressure plate.
Claim 3
Dependent Claim
30 words
The load handling mechanism according to claim 1, in which the arm consists of two telescopically extensible parts to make the clamping pressure plate reach varying distances over the platform.
Claim 4
Dependent Claim
59 words
The load handling mechanism according to claim 2 in which the first power operated means contains at least one pressure fluid jack connected to a fluid supply circuit including a pressure relief valve having an adjustable biasing member, the jack also comprising an actuating mechanism for automatically adjusting the biasing member in response to the extension of the arm.
Claim 5
Dependent Claim
33 words
The load handling mechanism according to claim 3, further including means for adjusting the pressure in the fluid supply circuit to maintain a minimum force required for clamping the material to be handled.
Claim 6
Dependent Claim
21 words
The load handling mechanism according to claim 1, having a resilient material covering a clamping side of said clamping pressure plate.
Claim 7
Dependent Claim
29 words
The load handling mechanism according to claim 1, in which said clamping pressure plate is provided with means by which it is swivel-mounted on an extension of said arm.
