The invention discloses a mobile crane operation condition video auxiliary observation system which comprises a mobile crane main body, a camera, a camera mounting bracket, a display and operation module, a connecting line, a synchronous reel for winding and unwinding the line and a guide wheel device. The mobile crane operation condition video auxiliary observation system is characterized in thatthe camera is mounted at the top end of a suspension arm through the camera mounting bracket, the display and operation module is installed in front of an operator in an operation room, the connecting line is laid on the suspension arm and synchronously winds and unwinds the line through the synchronous reel installed near a hinge fulcrum at the lower end of the suspension arm when the suspensionarm stretches out and draws back, the guide wheel device is installed at the top end of the suspension arm and located between the camera and the synchronous reel, guide wheels cannot rotate, the connecting line is wound for several circles when passing through the guide wheel device, and the operator observes video images transmitted back by the camera through the display screen. By means of themobile crane operation condition video auxiliary observation system, the visual field range of the crane operator is expanded by utilizing the video auxiliary observation system, the operation is convenient, the operation efficiency is improved, the blind area is reduced, and the operation safety is improved.
