Claim 14:
15. A method for monitoring lift events at a construction site comprising:
accessing a first timeseries of load values output by a load sensor, coupled to a crane hook, during a first time period for a first lift event;
accessing a first timeseries of motion values output by a motion sensor, coupled to the crane hook, during the first time period;
identifying a type of an object carried by the crane hook during the first time period based on the first timeseries of load values and the first timeseries of motion values;
selecting a load handling specification for the object based on the type of the object;
accessing a second timeseries of motion values output by the motion sensor during a second time period succeeding the first time period for the first lift event;
in response to the second timeseries of motion values deviating from the load handling specification, activating an object motion alarm for the object and generating a motion control flag during the second time period; and
generating a lift event record defining the type of the object and comprising the motion control flag.
