The present invention relates to a system for determining the mass of a payload moved by a working device of a machine, comprising: a lifting-gear element that is movable along a path and is designed to move the working device; a sensor system that is designed to provide a plurality of machine-status signals which indicate a status of the machine; a force sensor system that is designed to provide a lifting-force signal that indicates a force on the lifting-gear element; and a control device that is designed: to use system parameters for load determination that originate from pre-configured CAD data, preferably CAD data that has been pre-configured at the factory, and/or from continuous calibration of system parameters; to carry out calibration using the pre-configured parameters as initialisation if unsatisfactory results are achieved; to carry out the calibration in an unloaded state, i.e. when the working device is empty, with automatically predefined stimulation trajectories being used for the machine or instructions being provided to the operator for stimulating the parameters; to log the system statuses using the sensor and to carry out a system identification of this information; and to determine a mass of the payload on the basis of identified and/or pre-configured system parameters and system statuses, preferably on the basis of a position, a speed, an acceleration of the lifting-gear element and/or a force or torque on the lifting-gear element.

The dimensions of an object are measured as it is transported by a forklift within an area of measurement. A first scanner is on a first side of the area of measurement; a second scanner is on an opposite second side and across the first scanner. The first and second scanners provide a dual-head scanner arrangement to capture dimensions of the object. A third scanner is on the first side of the area of measurement, parallel to the first scanner. The first and third scanners are configured to capture speed and direction of the object. Each scanner has a processor to operate it. The first and second scanners are synchronized, and operation of the first and third scanners is correlated. Placement of the first and second scanners establishes a width of the area of measurement and the first and third scanners establish a length thereof.

A hydraulic mass-determining unit arranged for determining the mass of a load held by a hydraulic fluid system, the mass-determining unit is adapted to be connected to a hydraulic pump at a first fluid connection and a hydraulic actuator of a lifting device at a second fluid connection, the mass-determining unit comprises a first pipe arranged for connecting the first fluid connection and the second fluid connection, and at least one pressure sensor arranged to measure the pressure in the first pipe, wherein the mass-determining unit further comprises a flow regulator with a pressure compensator, where the flow regulator is serially connected to the first pipe to regulate the flow in the first pipe, and one of a pressure switch arranged for measuring the pressure difference over the flow regulator, and for sending a signal to the pressure sensor to measure the pressure in the first pipe when the pressure difference is above a preset value, or a magnetic field switch that comprises a magnet attached to the pressure compensator and a detecting unit arranged for detecting whether the magnet and the pressure compensator are in an initial position, and for sending a signal to the pressure sensor to measure the pressure in the first pipe when the detecting unit detects that the pressure compensator is not in the initial position, and a processor for based on the measured pressure in the first pipe by the pressure sensor calculating a mass of the load.

An attachable weighing scale for forklifts has a plurality of weighing modules connected within an outer cover. The weighing modules are connected to the forks of a forklift within the outer cover around the forks in order to facilitate weighing of loads.

A pallet sled includes a pair of tines extending forward from a base. A load wheel supports each of the pair of tines. The load wheels are each configured to move away from the respective tine to lift the respective tine upward relative to a support surface on which the load wheel is supported. A processor on the pallet sled records usage of the sled, such as lift cycles, location over time, battery condition, lift height, weight lifted, distance traveled, and the like. A communication circuit may be configured to send data from the pallet sled to a remote server. An identification reader may be configured to read an identification tag of an object supported on the pair of tines, such as an rfid tag on a pallet.

This disclosure describes a collection bin for a waste collection vehicle. The collection bin includes a weighing system with a processor for measuring the weight of material collected from each waste container and associating this weight with appropriate data, such as the owner of the waste container.

A wheel loader includes a lift arm, bucket, a lift cylinder that rotates the lift arm, a hydraulic force detection unit that detects a hydraulic force of the lift cylinder, an arm angle detection unit that detects a rotation angle of the lift arm, and a controller that calculates a weight of the load. A hydraulic force measurement unit measures a hydraulic force with the rotation angle of the lift arm within a predetermined measurement angle range; and a hydraulic-force-change-rate calculation unit calculates a change rate of the hydraulic force with respect to the rotation angle of the lift arm, and then calculates a new hydraulic force change rate within the measurement angle range. The controller corrects an error of the weight of the load occurring due to the inclination angle of the body on the basis of the new hydraulic force change rate calculated by the hydraulic-force-change-rate calculation unit.
