Abstract
A crane safety system providing a view of the operation of the crane to the crane operator is disclosed. The crane safety system comprises: (1) a camera sub-system having a monitor providing images to the operator, (2) a sensor sub-system for determining the presence of an object in the path of the cranes operating trajectory, and (3) a camera control device that directs and controls the camera to capture images and display the images on the monitor, the images selected by the control device based upon actions taken by the crane operator, or caused by events occurring proximal to the camera boom that are detected by the sensor sub-system. The control device further controls the sensor sub-system to select signals for processing to identify the proximity and direction of movement of the object relative to the crane. If the object is within a pre-defined distance, the control device sends an alarm signal to the monitor.
