Patent ID: 6985085

Claim:
A device for warning a crane operator, the warning related to an object undetected by the crane operator, the object in the path of the motion of the crane boom, the device comprising: a sensor mechanism, the sensor mechanism sending a signal to an area near to the crane boom, the sensor mechanism detecting the signal interacting with an object near to the crane boom, the signal identifying the proximity and direction of movement of the object relative to the crane boom; a steerable camera for acquiring images in an area near to the crane boom; a monitor for displaying images sent by the camera; a control mechanism for controlling the sensor mechanism, said sensor control mechanism comprising causing the sensor mechanism to send signals, the control mechanisms for processing a detected signal interacting with the object and the control mechanism further controlling the sensor mechanism and the camera according to processing of the detected signal; whereby the control mechanism detects objects in an area near the crane boom steers and causes the camera to send images of said object to the monitor, and the operator observes the object in said monitor.
