Abstract: The present disclosures relate generally to a tilt compensation apparatus and a tilt compensation method therefor. The tilt compensation method includes: S1: performing tilt angle calibration and horizontal rotation angle calibration on a weighing system; S2: selecting to set different specified tilt angles and different specified horizontal rotation angles, and measuring weights, tilt angles, and horizontal rotation angles under different loads; S3: calculating a weight compensation value based on the set specified tilt angles and the set specified horizontal rotation angles as well as the weights, tilt angles, and horizontal rotation angles obtained through measurement; and S4: calculating an actual weighing weight based on an actual measured weight of the weighing system and the weight compensation value. These disclosures provide more, accurate tilt compensation for weighing systems having a column-type load cell.

Abstract: One variation of a method for monitoring lift events at a construction site includes: deriving a lifting profile from a first timeseries of load values, output by a load sensor coupled to a crane hook, during a first time period; deriving an oscillation characteristic from 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 lifting profile and the oscillation characteristic; 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; and, in response to the second timeseries of motion values deviating from the load handling specification, activating an object motion alarm for the object.

Abstract: A configurable-width industrial weighing scale configured to hang directly from one of multiple engine-powered lifting machines and/or to couple to a quick-attach plate or other attachment means of an engine-powered lifting machine and configured to directly support a lifting element and/or couple to a quick-attach plate or other attachment means of a lifting element. A weighing element includes front and rear plates in parallel with one another and a weighing assembly therebetween. The weighing assembly may include a strain gauge-based load cell, a shock absorber, a mechanical preload adjustment to control a vertical difference between the front and rear plates, a mechanical linearity control to adjust an angle of the weighing assembly, a carriage alignment bolt to compensate for an uneven surface of a lifting carriage of the engine-powered lifting machine, and/or a mechanical adjustment to compensate for a distance between the front plate and a load.

Abstract: A load cell with a Roberval structure having an anti-offset function, and a weighing device are disclosed. The load cell includes strain detection elements mounted on an elastic element which includes a loading portion for receiving a load from a connector, a fixing portion for fixing the elastic element, a strain generation portion for converting the load into deformation, and a parallel guide beam for transferring the load and keeping the loading portion translational when loaded. The strain generation portion includes at least one hollow cavity body. The loading portion and the fixing portion are respectively located on left and right sides of the strain generation portion. The parallel guide beam is located at upper and lower portions of the strain generation portion A center of rotation and a geometric center of the strain generation portion coincide when the load cell with the Roberval structure is loaded.

Abstract: A weighing device and a weighing method, with central digital measured value correction. The weighing device is simulated on a central analytical unit including a digital function simulator of the weighing device. The digital function simulator of the weighing device is trained by a training device so that errors of measurement of the weighing device can be compensated. In this way, it is possible to obtain reliable and precise weighing results with weighing devices of little complexity.

Abstract: A payload measurement system can be used to measure the payload added to a machine supported on a plurality of walking beams. A plurality of load cell sensors is mounted to the walking beams in locations where, when the walking beam bends, the sensors are placed under load. The load cell sensors include a symmetrical strain bar having first and second mounting ends connected by a connecting span, wherein the end thickness is greater than the span thickness of the connecting span. The connecting span is disposed between and spaced apart from an upper plane and a lower plane with which the surfaces of the mounting ends are aligned.
