#CMT# #/CMT# The device has driving arms connected to respective door leafs and to a driving lever, and driving mechanisms (61, 62) closing a door. The arms, lever and the mechanisms form a driving unit, and a retractable stop (50) retains the unit when the unit is in a determined open position such that one leaf is found in the open position. A closure control formed by a cam, string (9) and a hollow tube (10) cancels the retention of the unit for a determined time and closes the door. An end of the lever acts on the unit to place the unit in the open position. #CMT#USE : #/CMT# Used for controlling opening or closing of a door closing a passage such as an opening in a cage, enclosure, working chute or fixed chute for controlling passage of animals such as cattle. #CMT#ADVANTAGE : #/CMT# The device permits to maintain the door in the open position during waiting of the animal and allows a user to remotely control the closing of the door.
