The invention belongs to the field of quay cranes, and particularly relates to a quay crane pitching emergency system. An emergency main motor control loop used for controlling an emergency main motor M1, an oil pump motor control loop used for controlling an oil pump motor M2, a low-speed brake electromagnetic valve control loop used for controlling a low-speed brake electromagnetic valve and a high-speed brake control loop used for controlling a high-speed brake are arranged in the pitching emergency cabinet. A power supply circuit for outputting a control power supply from the incoming power supply; the cabinet door of the pitching emergency cabinet is provided with function switch buttons in each loop and power supply circuit. The emergency operation efficiency of the quay crane in the initial assembling, installing and debugging process is remarkably improved, and troubleshooting is facilitated.
