If a stunning box is used, it should be narrow enough to prevent the animal from turning around. The floor should be non-slip so the animal can stand without losing its footing. It is much easier to stun an animal that is standing quietly. Only one animal should be placed in each stunning box compartment to prevent animals from trampling on each other.
Most large plants restrain cattle in a conveyor restrainer system.
There are two types of conveyor restraints, the V restrainer and the new center track system. In a V restrainer system, the cattle are held between two, angled conveyors. In the center track system the cattle ride astride a moving conveyor. A very humane position for cattle. Cattle are restrained in a comfortable, upright position.
