13/032439

Inventors:

Steven GAUTHIER - Inverness IL, US
Venkata R. HOGIRALA - Mount Prospect IL, US
Alexander NIKON - Wheeling IL, US

International Classification:

B66F 9/075
G08B 21/00
G01G 7/00
G01G 3/14
B23P 17/04

US Classification:

414 21, 340666, 177201, 177211, 29428

Abstract:

A weight sensing apparatus for a lifting device is disclosed that comprises at least one lifting chain attached to a load-engaging device at a first end and a frame at a second end, the load-engaging device being movable with respect to the frame when a lifting force is applied via the at least one lifting chain, at least one force translating arm fixedly attached to a sensor shaft at a first end and rotatably attached to the at least one lifting chain at a second end, the second end of the at least one force translating arm being attached to the at least one lifting chain between the first and second ends of the at least one lifting chain, and a torque sensor mounted on the sensor shaft that is configured to measure torque applied to the sensor bar by the at least one force translating arm when the lifting force is applied to the at least one force translating arm by the at least one lifting chain.

Abstract:

A weight measuring device includes a first link coupled to one end of a load to be measured. A second link is coupled to another end of a load to be measured. The first and second links include respective sections of a housing configured to place a spring in increasing compression with respect to increasing load on the first and second links. A hall cell and magnet are coupled between the first and second links to enable relative movement therebetween. The hall cell generates a signal related to an amount of movement of the first link with respect to the second link.
