Abstract

An apparatus for immobilizing cattle with a horizontally oriented inside ladder and a horizontally oriented outside ladder that is parallel to the inside ladder. The inside ladder is configured to slide laterally relative to the outside ladder. The top rail of the inside ladder is parallel to and spaced apart from the top rail of the outside ladder, and the bottom rail of the inside ladder is parallel to and spaced apart from the bottom rail of the outside ladder. The inside and outside ladders each comprises a plurality of vertically oriented, equally spaced rods that extend from the top rail to the bottom rail. The proximal end of the inside ladder is attached to a hydraulic cylinder that slides the inside ladder laterally relative to the outside ladder.

An apparatus for immobilizing cattle comprising:

(a) a horizontally oriented inside ladder;
and
(b) a horizontally oriented outside ladder that is parallel to the inside ladder;
wherein the inside ladder is configured to slide laterally relative to the outside ladder;
wherein each of the inside ladder and the outside ladder comprises a top rail and a bottom rail, the top rail of the inside ladder being parallel to and spaced apart from the top rail of the outside ladder, and the bottom rail of the inside ladder being parallel to and spaced apart from the bottom rail of the outside ladder;
wherein the inside ladder comprises a plurality of vertically oriented rods that extend from the top rail of the inside ladder to the bottom rail of the inside ladder, and the outside ladder comprises a plurality of vertically oriented rods that extend from the top rail of the outside ladder to the bottom rail of the outside ladder;
wherein the plurality of vertically oriented rods of the inside ladder are spaced equally apart from one another across an entire length of the inside ladder, and wherein the plurality of vertically oriented rods of the outside ladder are spaced equally apart from one another across an entire length of the outside ladder;
wherein each of the plurality of vertically oriented rods of the inside ladder has a central axis, each of the plurality of vertically oriented rods of the outside ladder has a central axis, and the distance between the central axes of each adjacent rod on the inside ladder is equal to the distance between the central axes of each adjacent rod on the outside ladder;
wherein the inside ladder has a proximal end, and the proximal end of the inside ladder is attached to a hydraulic cylinder that slides the inside ladder laterally relative to the outside ladder;
and
wherein the central axes of the vertically oriented rods of the inside ladder are vertically aligned with the vertically oriented rods of the outside ladder.
