摘要: There is described a method for confirming delivery of bulk material from a bed of a dump truck based on hydraulic pressure. The dump truck has a driving device moving the bed between a rest position and a delivery position. The method generally having: using a hydraulic pressure sensor, measuring a plurality of hydraulic pressure values indicative of pressure of a hydraulic fluid of the driving device as the bed is moved; and using a controller communicatively coupled to the hydraulic pressure sensor: monitoring a slope at which at least some of the plurality of hydraulic pressure values vary over a given period of time; and generating a delivery confirmation indicative that a delivery of the bulk material has occurred based on a comparison between said monitored slope and a delivery slope threshold.

摘要: A work vehicle, a method of determining a weight of a payload supported by a work tool mounted to an upper structure of a work vehicle, and a method of calibrating a weight of a payload supported by a work tool mounted to an upper structure of a work vehicle are provided. The work vehicle includes an undercarriage having a plurality of ground engaging members supporting the work vehicle, an upper structure rotatable relative to the undercarriage about a vertical axis, a rotation sensor configured to determine a rotation angle of the upper structure relative to the undercarriage, a work tool mounted to the upper structure and configured to support a payload, and a controller configured to determine a weight of the payload based at least partially on the rotation angle of the upper structure relative to the undercarriage.

摘要: A method for estimating load weights for an implement of a work vehicle may include controlling movement of a boom of the work vehicle such that the boom is moved across a plurality of overlapping measurement regions defined along an angular travel range of the boom, wherein each measurement region is overlapped by at least one adjacent measurement region of the overlapping measurement regions across the angular travel range. The method may also include receiving load-related data associated with a load weight for the implement as the boom is moved across the overlapping measurement regions and determining a region load weight for at least one measurement region of the overlapping measurement regions based on the load-related data. In addition, the method may include calculating a final load weight for the implement based on the region load weight(s).

摘要: A weight measuring hitch ball assembly is described. The assembly can include a hitch ball having a ball and a lower portion. The assembly can also include a body portion defining a hitch ball opening that slidably receives the lower portion of the hitch ball. The assembly can further include a load measurement device operably associated with the body portion and the hitch ball to determine a magnitude of a force acting on the hitch ball. Additionally, the assembly can include a hitch mount interface configured to interface with an attachment structure that facilitates coupling the weight measuring hitch ball assembly to a tow vehicle.

摘要: Hydraulic valve circuitry adapted for hydraulic connection to a lift truck having a mast and at least one lift cylinder for alternately raising and lowering the mast. The hydraulic assembly is also adapted for hydraulic connection to an attachment to the lift truck, the attachment having opposed clamps actuated by respective clamp cylinders. The hydraulic assembly preferably comprises a valve circuit capable of causing the at least one lift cylinder to be an accumulator.

摘要: Hydraulic valve circuitry adapted for automatic weight-responsive control of load-clamping members of a load-lifting system having a free lift mast. The load-lifting system generally includes one or more fluid power actuator for applying a gripping force to a load, at least one elongate, longitudinally-extensible fluid power lifting device having a free lift range of motion and at least one main lift range of motion, and manually operated load-clamping and load-lifting selector valves. The hydraulic valve circuitry provides, independently, weight-responsive control of the load-clamping members when lifting a load, full-time automatic weight-responsive force control of the load-clamping members without concurrent manual actuation of load-clamping or load-lifting selector valves, and equalization of sensed load weight so that the sensed load weight is substantially independent of the longitudinally-extensible position of the lifting device.

摘要: Embodiments of a system and method for weighing animal feed ingredients using a bucket loader to dispense a measured quantity of ingredient into a feed scale are disclosed. A weight of the feed ingredient in the bucket is determined and compared to a weight of the feed ingredient subsequently transferred from the bucket to the feed scale. Based on the comparison, data received from components of the system is calibrated to increase accuracy of future weighings of the feed ingredient.

摘要: A method, for evaluating the variation in the dynamic load borne by a tire comprising a front axle and a rear axle, comprises steps during which: the pressure of the air contained inside the tire is measured, a difference in load borne by the tire is determined as a function of the transfer of the total load of the vehicle between axles and of the position of the tire on the vehicle and, using a tire model that is preestablished, a pressure differential is determined, a corrected pressure value is determined, on the basis of the corrected pressure values, a reference pressure is determined, and the difference between the measured pressure in the reference pressure is calculated, and the variation in dynamic load borne by the tire is determined on the basis of the model of the tire.

摘要: A method of weight determination of a load carried by a lifter of a lifting device is based on at least one upward and one downward displacement of the lifter by means of a hydraulic actuator. A pressure signal is provided by means of a pressure sensor, and a position signal is provided by means of a meter. The weight of the load is determined on the basis of the pressure signal and the position signal. The position signal is registered as a function of time, an acceleration dependent parameter is determined on the basis of the variation of the position signal, and the weight de-termination is performed in dependence of said acceleration dependent parameter, where during the upward and downward displacement of the lifter, the flow of a hydraulic fluid through the hydraulic system is limited by a bi-directional flow controller. Furthermore, a weighing device is dis-closed.
