ABSTRACT:
A safety bypass gate is provided for use with a livestock management system having a sorting scale arranged between watering and feeding areas. The safety bypass gate changes from a closed position to an open position to provide an emergency exit from the watering area when a condition exists that prevents animals from passing over the sorting scale. The safety bypass gate includes a pair of pivoting gate members and a channel member that fits over the top edges of the gate members to secure them closed. The channel member is attached to a pneumatic actuator that uses air pressure to hold the channel member in its locked position, and a spring return that moves the channel member to its unlocked position upon a drop in air pressure. Springs bias the gate members from their closed positions to their open positions when the channel member moves to its unlocked position.
