Improved coke chute systems (100) include a lock (130) that receives and automatically secures a coke-receiving conduit (110) to a coke vessel after the lock (130) is switched to a closed position. Contemplated systems may further be combined with a horizontally movable coke chute cover, or a cover that is moved by an actuator (114) that lifts and rotates the cover from a first position to a second position.
