Stall Barn Walk-thru

• HIGH EFFICIENCY AND PRODUCTIVITY FOR THE LOWEST INVESTMENT
• The WALK-THRU BARN (modern flat barn) is one of the most efficient milking barns available.
•  
• It handles large herds as easily as it handles small ones, yet gives the individual cow the attention so many dairy managers desire.
• The barn shown in the photo consists of 20 WALK-THRU STALLS and is equipped with 10 AUTOMATIC DETACHERS and 10 individual BACKFLUSH VALVES.
• A milking speed of 100 COWS PER HOUR is obtained with two milkers. Obviously the speed can be increased by doubling up on detachers and milking units. However, if you swing the unit between two cows they have more time in the stanchion and therefore have extra time to eat.

Operation

• Cows enter the milking area from the holding corral on an individual basis through one of the entrance gates.
•  
• The gate is operated by pulling on an overhead cable which activates a small air valve. This air valve sends a pressure signal to the entrance gate valve to open the gate.
• Only a momentary tug is required to open the gate and let one cow in. The cow pushes a sensing bar as she walks thru and automatically closes the gate behind her. If you need to let more then one cow in just hold the cable and the gate will stay open until you release it and the next cow trips the gate closed.
• The entrance gate was designed to prevent two cows from coming thru at one time and the closing trip lever will sense even very small cows reliably. The air operation makes this gate simple and low maintenance.
• Once the cow has entered the milking area she finds an empty stall and locks herself in the air operated locking stanchion. She activates the locking mechanism by touching the neck bar when she reaches down for feed in the feed manger.
• A manual push button is provided with the overhead controls to lock the stanchion in case a heifer does not want to put her head down.
• The head lock mechanism also mechanically locks the gate to the posts of the stall, that way we are not relying on just the air cylinder to keep the gate closed during milking.
• At this time the cow gets prepped by the milker and is provided with feed.
• Once the cow next to her is done and the detacher, milk retriever and back-flush have gone thru their cycle, the milker can attach the unit to the new cow.
• He then lets the previous cow out by pushing an air valve located on the overhead control panel. Pushing the valve unlocks the stanchion head lock and swings the whole stanchion forward and out of the way. The cow steps over the milk line (yes she will) and exits thru the stall. THUS THE NAME WALK-THRU!
• The walk-thru obviously provides you with the great advantage of individual cow movement. A cow that takes longer to milk does not hold up the rest of the barn. In addition a cow may be treated or pregnancy checked right in the stall.
•  
• PBI Ross-Holm can also provide a feature called "THE AUTO CLOSER". When the cow walks out thru the stanchion a wand senses her and automatically closes the gate behind her. After the gate is closed it is all set for the next cow without requiring action from the milker. With the time saved the barn becomes more efficient and productive.
• The design of the dividers provide ample room for the milker to work; also to install two detachers and back-flush units if desired and for the in place wash up manifolds.
• The single loop divider between the two cows is made longer to prevent one cow from pushing the one next to her over. This lines all the cows up better and makes walking between them to attach the milking unit a breeze.

Construction

• Construction of the PBI Ross-Holm Walk Thru Stalls is extremely heavy. The main posts are made of 3- inch square tubing, the gates 2 inch square tubing, the single dividers (between two cows) are made of 1-7/8 OD. pipe and the double dividers (where the milking units are) are made of 1-5/8 OD. pipe.
• The entire stalls are HOT DIPPED GALVANIZED and designed to bolt together
• in the barn. No welding is required. This includes the supports for the auger system, feeders, detachers, controls and even the pipe line.
