ABSTRACT:
A coke oven hood car is provided with a coupling opening defined on two sides by a pair of spring biased stop bars which can be engaged by a quenching car driver element which is extendable and retractable into and out of, respectively, the coupling opening by a hydraulic driver element cylinder-piston actuator. A hydraulic brake control cylinder-piston actuator is provided with a piston rod adapted to be actuated by the driver element of the quenching car when the driver element is extended into the hood car coupling opening. A hydraulically operated brake system is provided for braking the hood car when the quenching car driver element engages the hydraulic brake control cylinder-piston actuator piston rod. An emergency brake control is provided and consists of a switching control means on the quenching car connected to the driver element cylinder-piston actuator and a switching cam mounted at a selected position along the path of travel of the quenching car for actuating the switching control means to operate the driver element cylinder-piston actuator for retracting the driver element out of the hood car coupling opening and permitting application of the brake system.
