Abstract: A forklift scale to measure a load carried by a pair of forks of a forklift that includes a fork carriage to movably position the forks. The forklift scale includes a pair of load cells that are configured to mount to the fork carriage independent of each other and to removably receive a respective fork of the forklift. Each load cell includes a structural arrangement that couples the respective fork to the fork carriage during operation such that an entirety of the load carried by the forks during operation is transmitted to the carriage via the pair of load cells. Other related forklift scales, load cells thereof and methods of measuring a forklift load are also provided.

Abstract: A waste bin scale to measure a cantilevered load carried by lift members of a lift system. The waste bin scale includes a base coupleable to the lift system, a lift member support system; and a plurality of load cells. Each load cell is coupled between the base and the lift member support system, and includes a structural member configured to deform during application of a load applied by the waste bin, where the deformation is indicative of the applied load. Other related waste bin scales, load cells therefor and methods of measuring waste bin scale loads are also provided.

Abstract: A forklift scale to measure a load carried by a pair of forks of a forklift that includes a fork carriage to movably position the forks is provided along with a method to measure the load. The forklift scale may include a base coupleable to a fork carriage, a fork support system to receive the pair of forks, and a plurality of load cells configured to deform elastically in response to a load carried by the forks. The method to measure the load carried by the forks may include obtaining signals from the load cells and processing the signals to obtain a load value indicative of a load shared by the pair of forks. Other related forklift scales, load cells therefor and methods of measuring a forklift load are also provided.

Abstract: A lift and weighing system comprises two lift arm assemblies directly and mechanically coupled to at least two weight-measuring devices. The system may further comprise a first elongated support member extending between and coupling to the two weight-measuring devices, and a second elongated support member interposed between and rigidly affixed on opposing sides thereof to the lift arm assemblies and/or the weight-measuring devices to protect the weight-measuring devices from side loads. The system further comprises at least two end plate adaptors respectively positioned on and rigidly attached toward opposing ends of the elongated support member and adapted to rotatably engage an external actuating system configured to operate the lift and weighing system. In another embodiment, the weight-measuring devices are housed in the elongated support member.

Abstract: A cement mixer truck and a weight measuring system is provided, comprising a mixing chamber, at least one rear roller bearing assembly, and a front mounting assembly. The rear roller bearing assembly includes a roller bearing and a first weight measurement device. The first measurement device can be configured to generate a first set of electrical signals corresponding to a load generated by the mixing chamber at the roller bearing. The front mounting assembly includes an engagement device and a second weight measurement device coupled to the engagement device. The second weight measurement device can be configured to generate a second set of electrical signals corresponding to a load generated by the mixing chamber at the engagement device. Means for electrically coupling the first and second weight measuring devices can calculate the weight of the chamber or the contents therein, or both.

Abstract: A weight measurement apparatus of the type for determining the weight of a load placed on a wheeled vehicle. The apparatus includes an elongated load bearing member coupled between the load and the wheels. The load bearing member has two apertures that extend completely through the load bearing member, and load sensors attached to the walls of the apertures for calculating the stress in the apparatus created by the load. The apparatus can further include a decoder for converting the stress measurement to a weight value and an onboard display device for displaying the weight of the load to the vehicle operator. The apparatus may be sized and shaped to retrofit existing structural components of a truck, thereby adding a weight measurement capability to the vehicle.

Abstract: A weight measurement apparatus of the type for determining the weight of a load placed on a wheeled vehicle. The apparatus is releasably connectable to the vehicle at a location between the axles of the vehicle, which retain the wheels, and the portion of the vehicle retaining the load. The apparatus includes strain gages for calculating the stress in the device created by the load, a decoder for converting the stress measurement to a weight value, and an onboard display device for displaying the weight of the load to the vehicle operator. The apparatus may be sized and shaped to retrofit existing structural components in the suspension system of a truck, thereby adding a weight measurement capability to the vehicle.

Abstract: A method and apparatus for digitizing and transmitting one or more analog signals simultaneously over a two-wire line. The two-wire line not only provides the power required for the digitizing circuit and sensor, but is used also to transmit the analog information in a digital pulse train encoded with the power supply current. All data pulses are transmitted as the quiescent current of each analog coder module and its associated transducers connected to it. These data pulses start and end by transmission of a digital sync current pulse which separates transmission of each analog data pulse. The width of each data pulse conveys the desired information. A circuit for generating the pulse train having only two amplitudes but pulses having a variable width includes an SR flip-flop coupled to the output stage.
