Knuckle Puller

The model K6D-A Knuckle Puller has been designed to replace and

operation that requires manually pulling a large muscle from the carcass of a

bovine.

To overcome this problem we have attempted to design a piece of equipment

that is pneumatically operated and therefore eliminate the labor-intensive aspect of

pulling knuckles. The operation consists of someone cutting or marking the muscle

on the carcass. The operator of the knuckle puller hooks the muscle behind the

patella bone. Using the bone as leverage he then engages the cylinder to extend

against the shank bone. The knuckle is pulled from the bone and put on a conveyor

for further trimming.

The majority of the components used in the knuckle puller are made of

stainless and aluminum. All parts coming in contact with the product are made of

stainless steel. Considerations of design and material selection have resulted in a

machine that is easily maintained in a sanitary condition. All mechanical

components are ruggedly constructed which should provide for years of low

maintenance operation.
