Abstract: A crane collision avoidance system is disclosed herein that is configured to monitor a crane and an environment surrounding the crane. The crane collision avoidance system may include one or more devices or sensors that are selectively attached to a crane. In various embodiments, the crane collision avoidance system may include a computer system configured to use images or information obtained via the devices or sensors to monitor a crane operator's blind spots and movement of the crane and its components, detect potential collisions with danger objects within the environment surrounding the crane, detect counterweight movement, monitor a load zone, detect when a boom or any other component of a crane has become energized, and/or otherwise provide improved situational awareness to a crane operator.
