System for determining crane status using optical and/or electromagnetic sensors

A crane comprising:

• a lower works having one or more ground engaging elements;
• an upper works connected to the lower works, the upper works having a boom;
• and
• a system for determining a crane status, the system comprising:
• a sensor assembly positioned to have a line of sight along at least a portion of a length of the boom or the lower works, the sensor assembly configured to detect light transmission and output sensor information;
• and
• a computer configured to receive the sensor information and determine the crane status based on the sensor information,
• wherein the determined crane status includes at least one of:
• vertical boom deflection, side boom deflection, boom length, boom section length, number of boom sections, type of boom sections, boom tip position, boom attachment installation condition and position, boom attachment length, boom attachment offset, anti-two block (ATB) component status, ATB status of the crane, reeving configuration, optimal reeving configuration, retaining pin installation status, sheave rotation, boom pick point, flexible member condition, pendant rope length, correct positioning of crane components, number of falls, number of flexible members, differences in construction from desired or expected construction, trolley position, tower crane mast twist, boom twist, sway, trailing boom monitoring, jib rigging mode, and flexible member speed.
