Full-Laval - Visi Claw Cluster for Cow Milking in Parlor Systems

SHARE

The Visi-Claw cluster, created by FULL-LAVAL, is engineered to facilitate cow milking in both parallel and rotating parlors, where cows are milked from the rear. This claw can also be employed in herringbone parlors. The design addresses several key challenges: the inlets are closely positioned to allow attachment through the cow's back legs, and the unit is made from highly durable, transparent material to enable workers to monitor milk flow from each liner. The claw accommodates old cows with non-standard udders and features large diameter inlets to sustain milk flow from the highest-producing cows. It is equipped to fit standard milk tubes (16mm) and less commonly used 22mm tubes. The design prevents back flushing when a liner slips and fits comfortably in a farmer's hand while efficiently evacuating milk, ensuring it doesn't flood even at flow rates of 12 liters per minute.

The Visi-Claw cluster was designed by FULL-LAVAL in search of a solution for milking the cows in a parallel or a rotating parlor, where the cows must be milked from behind. Of course this claw can also be used in a herring bone parlor also.

We have observed, during milking that there are several constrains that must be solved when milking a cow from behind:

The inlets of the claw must be as close as possible to each other in order to being able attaching it to the teats through the back legs of the cow.
The claw must be transparent, so that even a non-professional worker can see all four strips of milk from each liner during milking.
The transparent material of this claw must be as unbreakable as possible and still glass transparency must be obtained in order to see the milk inside from each angle.
Its inlets towards the liners must be designed in such a degree, to enable milking even old cows with a non-standard and classic udder.
The inlets diameter must be as large as possible to support the milk flow of fastest cows in the herd and still be easy to handle by the farmer
Its outlet nipple, has to fit normal size of milk tubes (16 mm) and also 22mm tubes very seldom used in such parlors.
The claw has to prevent back flushing of milk when one of its liners is slipping.
The external size of the claw has to fit even a small hand of the farmer and still has to be able evacuating the milk as fast as possible, never being flooded even at 12 lit. of milk per minute.

All those restrictions were solved when designing this innovative claw.
