One variation of a method for tracking lift events at a construction site includes: accessing a timeseries of load values output by a weight sensor, coupled to a crane hook, and a first geospatial location of the crane hook during a first time period; deriving a lifting profile at the first geospatial location from the timeseries of load values; deriving a weight of the object from the timeseries of load values; identifying a type of the object carried by the crane hook during the first time period based on the lifting profile; accessing a second geospatial location of the crane hook during unloading of the object from the crane hook; and generating a lift event record defining the type of the object, the weight of the object, a pickup location of the object at the first geospatial location, and a drop-off location of the object at the second geospatial location.

A crane hook block includes a frame, at least one pulley rotatably connected to the frame, a load hook connected to the frame, at least one sensor arranged on the crane hook block and designed to detect at least one ambient parameter and/or at least one status parameter of the crane hook block, and an interface connected to the at least one sensor and designed to transmit the data received from the at least one sensor.

One variation for a system for tracking lifting events at a construction site includes: a chassis configured to couple to a crane block of a crane at a construction site. The system further includes a first idler assembly including a first cable idler, a first idler arm, and a first position sensor coupled to the first idler arm. The first idler arm supports the first cable idler on a first side of the chassis and biases the first cable idler inwardly toward a first cable loop coupled to the crane block. Additionally, the system includes a controller configured to, during a lift event: read a first position value from the first position sensor; predict a weight of the load carried by the crane block based on the first position value; and generate a lift event record containing the weight of the load carried by the crane block.

The invention relates to an apparatus for weighing the hook load of a crane, wherein different measurement accuracies can be set at the apparatus, comprising at least one measurement device, at least one retaining pin, and at least one coupling section. The invention is additionally directed to a hook block and to a crane having a corresponding apparatus.

Method and apparatus for detecting overload distortion A method and apparatus for detecting overload distortion in lifting and the like gear is disclosed. The apparatus includes a hook with two reference points thereon defining, in the undistorted state of the hook, a reference dimension. The hook also has a standard dimension provided on the hook and conveniently accessible for reference purposes. The standard dimension is also a pair of points and one of this pair is coincident with one of the reference points thereby forming a triangle of points on the hook.
