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.

A refrigerator includes a cabinet defining an exterior configured for resting on a surface and an interior and a plurality of feet coupled with the cabinet along a bottom surface thereof. The refrigerator also includes a plurality of load transducers disposed between and in opposing contact with the cabinet and respective ones of the feet. The refrigerator further includes electronic circuitry including a non-transitory computer-readable medium configured to receive a signal corresponding with a gross weight of the cabinet from the plurality of load transducers and to determine the quantity of articles retained within the interior of the cabinet.

An agricultural vehicle including a container, which is mounted on at least one train of wheels, wherein the container rests by way of fixation brackets and load cells or weight sensors, preferably directly, i.e. without use of an intermediate chassis, on one axle or more forming the train of wheels. The vehicle container is mounted on the axle or each of the axles of the train under consideration by way of at least two pairs of load cells, wherein each pair consists of two load cells situated on opposite sides of a vertical plane parallel to the vertical planes containing the axes of the axles of a multi-axle train.

A positioning foot having a hydraulic shock absorber with a fluid-filled hollow cylinder (210), in which a piston (220) that moves axially between an advanced, spring prestressed position and a retracted position. The piston separates a front axial fluid space (214) and a rear axial fluid space (215) from one another in the hollow cylinder. Both fluid spaces are connected to one another in a fluid exchanging fashion via at least one throttle opening (223) in the piston. The piston is rigidly connected to a piston rod (221), which passes through the front fluid space and abuts a fixed stop (218) in the retracted position, in which the volume of the rear axial fluid space is minimized and the volume of the front axial fluid space is maximized. The spring prestress is dimensioned so that the weight of the device body moves the piston dampingly into the retracted position.

A processing device receives a multitude of measurements from an orientation sensor. The orientation sensor is mounted to a container. A determination is made, from the multitude of measurements, that the container is in an angular position where a composite weight of the container and contents of the container bear down on at least one weight sensor. The at least one weight sensor is mounted to the container. At least three readings of the composite weight are taken from the at least one weight sensor. A validation is made that each of the at least readings of the composite weight are: (1) within a minimum value and a maximum value; and (2) are within a difference of less than a predetermined amount to each other. In response to the validating, a composite weight value based on the at least three readings of the composite weight is stored.

A rocker pin load support includes a base plate, a rocker pin bolt, and a rocker pin piece having a cylindrical recess of a diameter greater than a diameter of an upper portion of the rocker pin bolt. The rocker pin bolt is mounted pivotally via a ball-shaped underside thereof in a cylindrical recess of the base plate and pivotally mounting the rocker pin piece via a spherical topside thereof. A bell-shaped cover of elastic plastic has an upper edge portion connected hermetically sealed to the rocker pin piece, and a lower edge portion connected hermetically sealed to the base plate, thereby forming a space for receiving an air or gas filling with the proviso that the gas or air volume is greater than a sum of volumes of portions of the rocker pin bolt and the rocker pin piece which portions are enclosed by the air or gas filling.

Method and apparatus for weighing an elongate object extending between a root end and a tip end thereof, said method including: providing a respective tip load measurement gauge and root load measurement gauge; and providing a suspending arrangement configured for suspending said elongate object from said tip load measurement gauge and from said root load measurement gauge; and suspending said object in a horizontal orientation; and recording a tip load and a root load from respective said load measurement gauges, said method being additionally characterised by: providing a weighing area; and fixing an inclinometer to said suspended blade and load gauge arrangement; and suspending said elongate object from said tip load gauge and from said root load gauge; and adjusting the horizontality of said elongate object in response to signals from said inclinometer prior to said step of recording said tip load and said root load. Alternatively, an inclinometer may be replaced by placing a first distance sensor at a first location on a ground surface; and placing a second distance sensor at a second location on said ground surface; and suspending said elongate object from said tip load gauge and from said root load gauge such that a said root end thereof is suspended proximate said first distance sensor and a said tip end thereof is suspended proximate said second distance sensor; and measuring a first distance between said first distance sensor and a said root portion of said elongate object and; and measuring a second distance between said second distance sensor and a said tip portion of said elongate object; and then adjusting the horizontality of said elongate object in response to said first and second distance readings prior to said step of recording said tip load and said root load.

A platform scale uses a method of detecting a center-of-gravity (COG) offset. A weight value of a load on a weighing platform is calculated. The weighing platform is allowed to reach a steady state. When the weight value exceeds a COG offset threshold, then a position of a load COG is calculated using a load COG position algorithm. Whether the calculated position is in a valid region of the weighing platform is determined. The weight value is displayed if the position is within the valid region; otherwise, the position of the COG is displayed. A display apparatus of the scale displays the weight value or the position of COG of the load. The platform scale alerts a user about a possible invalid weighing event by displaying an image indicative of the COG offset condition, ensuring effective and precise weighing.

To adapt a housing (2) to an uneven standing surface, an adjustment device (1) has a foot piece (3) with an internal thread (5) that defines a displacement axis (4). The foot piece is located in a recess (6) of the housing that is accessed from a surface of the housing that faces towards the standing surface. A cross-sectional profile of the foot piece perpendicular to the displacement axis coacts with the recess to prevent rotation of the foot piece about the displacement axis. A spindle (7) with an external thread (8) that cooperates with the internal thread of the foot piece allows axial movement of the spindle along the displacement axis. A levelling wheel (9), connected to the spindle by a rotation-blocking connection allows the spindle to be rotated relative to the foot piece.
