Abstract: A weighing system for a refuse truck having lifting means for engaging and lifting a refuse container. The weighing system comprises a transducer which is mounted on the lifting means of the truck for sensing the weight of the refuse container for producing an electrical analog signal. Electrical digitizing means convert and analog signal to a digital signal which is indicative of the weight which is sensed by the transducer. A limit switch is operatively connected to the transducer so that the transducer is energized at a point when a full container is supported by the lifting means and when an empty container is supported by the lifting means for the purpose of determining the weight of the refuse in the container.

Abstract: Weighing device mountable between a three-points lifting means of a tractor and a load or apparatus to be weighed, said device having two parallel frames adjacently connected to each other for limited movement, a measuring means being mounted between the frames, the connection between the frames being realized by means of stiff elastically deformable strips such as strips of stainless steel, covered at one or both sides with stiffening plates leaving only a small flexion region or by strips mounted to the upper and lower sides of the frames.

Abstract: A portable low profile mechanical scale is provided having a carriage with spaced side frames each with wheel means at one end and ground support means at the other end, spacers between the side frames holding them in fixed parallel relation, removable wheeled lift means engaging the side frames adjacent the ground support means for moving the side frames, a pair of torsion bars above said side members at two different parallel levels, one adjacent each side frame and supported thereon by triangular links fixed to the torsion bars at one end and supported on the side members at the other, a weigh bed movable vertically between the side frames and pivoted to the triangular links between the torsion bar and support on the side frames, a lever on each torsion bar adjacent said wheel lift means extending transversely toward each other, one above the other, a link connecting said levers midway between the side frames and a connector on the uppermost lever for connecting to a weight indicating mechanism.

Abstract: A pallet truck with a fork member movable in an up-and-down manner is provided with a plurality of load cells on the tines of the fork member for weighing loads carried by the pallet truck. Each load cell is mounted by a tine of the fork member, over which tine is floatingly mounted an elongated floating member extending substantially along the entire length of the respective tine member. Each floating member is supported by at least one ball bearing operatively associated with at least one load cells on the tine. A crosspiece is provided interconnecting the ends of the two floating members adjacent the main frame of the pallet truck, which crosspiece is fixedly secured to the ends of the floating members in order to provide stability and increased inertia to the entire floating mechanism. The ball bearings associated with the load cells are mounted adjacent a respective inner side-edge surface of the tine member, so that a wooden pallet with load may be more accurately weighed.

Abstract: There is provided a method and device for recording the weight of refuse material emptied from a container into a collecting vehicle by means of an unloading device. The gross weight of the filled container and the dead weight of the emptied container are determined while the container is being emptied by the unloading device of a refuse collecting vehicle. Each container is identified and the identification and weight data are supplied to a recording and control system. The device for carrying out this process is adapted to be integrated in the unloading devices of the collecting vehicle.

Abstract: A weighing apparatus for weighing eccentric loads for use with a forklift is provided, the weighing plate of the apparatus forms the loading surface of the forklift, three weight measuring systems or weighing cells which input a computing device engage with the weighing plate, one at the steering head and one each at the support struts in front of the rollers thereof. The coupling bars which operatively interconnect the steering head with the rollers are designed not to interfere with the weight measuring systems of the respective support struts.

Abstract: A device is provided with weighing apparatus mounted on the movable upper frame and means operable automatically in response to raising of the upper frame beyond its normal transport position to divert the weight of the drum from the base frame onto the weighing apparatus. Said means comprises a rotary catch which is mounted on the base frame and is automatically operable to engage first beneath the upper frame and then beneath a load-sensitive bar of the weighing apparatus in response to successive upward movements of the upper frame to and beyond its transport position and load-engaging members mounted on and slidable relative to the upper frame, which members are automatically operable through the medium of cams on the base frame and a pivoted flap on the upper frame to connect the load to and disconnect it from the base frame when the upper frame reaches its transport and weighing positions respectively.

Abstract: Method and apparatus for handling tobacco. Five to eight bales are compacted to reduce the transverse dimension of the bales, the compacted group being tied into a single pack. The disclosed apparatus for performing the method consists of a truck having a pair of jaws which are movable toward one another, which are rotatable and which are elevatable to permit the bales to be compressed, raised, rotated through 90.degree. and tied.

Abstract: A material handling and lift scale device comprising first and second rectangular frame members linked together by a parallelogram linkage system to confine relative movement between said frames to planar-parallel movement in a longitudinal direction only, said first frame member having forklift tines extending essentially perpendicular to said longitudinal direction, said second frame member adapted to be supported and controlled through a three-point hitch connection to a farm vehicle, hydraulic cylinder means connected between said first and said second frame members with the operative axis of said cylinder means aligned in said longitudinal direction and a pressure gauge connected to said hydraulic cylinder means to indicate fluid pressure changes within said hydraulic cylinder means resulting from support of material on said forklift tines tending to produce longitudinal relative motion between said first and second frames, said pressure gauge being calibrated in weight units to indicate directly the wei

Abstract: The weight of items carried by a fork lift truck may be measured by this fork lift scale. This fork lift scale consists of horizontally disposed load sensors connecting a crossbar frame to the crossbars of the fork lift truck. Forks are supported by the crossbar frame. Strain gages are mounted on the load sensors to sense the weight of items carried on the forks. The strain gages are mounted to sense vertical shear or bending in the load sensors. The strain gages are positioned on the load sensors and are electrically interconnected so that types of loading, other than vertical loading due to the weight of items placed on the forks, are rejected and not measured by this fork lift scale.

Abstract: This invention relates to improved weighing apparatus for fork lifts comprising a weigh bridge supported at each end thereof by load cells. The weigh bridge and load cells are built into the fork so that the overall height of the fork is kept to a minimum.

Abstract: A mounting adapter provides a quick attachment means for mounting or removing an electro-mechanical scale with respect to the lift frame of a fork lift truck. The scale comprises a scale frame, which supports the lifting forks, and also includes a plurality of deformable bolts each having strain gages thereon to sense deformation of the bolts when a load is placed on the forks. Circuit means produce output signals caused by deformation of the bolts and the circuit means also converts the signals to perceptive weight readouts. The mounting adapter includes transverse frame members to which the deformable bolts are secured. Clamping means clamp the frame members of the mounting adapter to the lift frame of the fork lift truck.
