Abstract: A device 1 includes a carrying body for carrying a load. The carrying body includes a first wall 3 which receives the load and an opposite second wall 2. Between the first wall and the second wall is a space in which a force sensor is provided. A part of the force sensor 4 is coupled to the second wall 2 and the other part of the force sensor extends beyond an edge of the second wall 2 so that the force sensor has some freedom to bend. An at least partially bendable force transmission body 5 is fixed to the first wall 3 and extends in a cavity 6 in the other part of the force sensor. Owing to the force transmission body 5 the force sensor is loaded only in a direction to which the force sensor is tuned.

Abstract: A portable scale for weighing drums, cylinders and other containers is describe.

Abstract: A portable platform-scale weighing system comprises a floor dolly and lift mechanism that allow a heavy low-profile platform scale to be used practically anywhere truck cargoes need to be weighed. The low-profile platform scale includes a shear-beam load cell on each of four corners that are lifted off the ground by the lift mechanism whenever the dolly is being rolled to a new job. The weighing system puts weight on each of the shear-beam load cells only when the lift system has lowered the low-profile platform scale onto a protective outrigger runner on each side and such runners are resting on the ground. Such runners have turned up steel wings that prevent side impacts to the shear-beam load cells. Various guides and pins keep the low-profile platform scale centered over the floor dolly and lift mechanism so that when it is lowered it will drop properly on the two outrigger runners and minimize contact between the lift mechanism and dolly during the weight mode.

Abstract: A scale for weighing a load, which is made up of a base (12), a weighing platform (34) for supporting the load and a load cell (36, 98) located below the weighing platform so as to alternate between an operational position, in which the weighing platform is supported by the load cell for measuring the weight of the load, and a neutral position, in which the weighing platform is supported by the base member for carrying the load. The scale further includes a contact member (40, 48, 116) located below the weighing platform (34) so as to reversibly come into contact with the load cell so that the load cell alternates between the operational position and the neutral position due to a relative movement between the load cell and the contact member. The scale further includes a mechanism (26, 52, 96, 110) for generating the relative movement.

Abstract: A hydraulic lifting device, such as a forklift, is provided and is capable of dynamically measuring the weight of a load being lifted. A plurality of pressure measurements are taken during the lift for a period of time, which are stored in memory. A computer program is operated on by a microprocessor to process the pressure measurements to filter unwanted signals associated with vibration and other mechanical disturbances. The pressure samples processed by the computer program correspond to a portion of the lift during which acceleration of the forks has ceased, allowing a closer correspondence between the weight lifted and the pressure of the hydraulic fluid sensed.

Abstract: A pallet truck has a rigid frame mounting a plurality of load cells. Ball and socket coupling devices are connected to the load cells and support a platform assembly. The frame and platform assembly are able to be elevated to lift and support an object to be weighed on the platform assembly.

Abstract: A weighing apparatus for a vehicle having tines in which a ramp is mounted on each tine in front of and in spaced relation to a weighing load bearing plate. The ramp and the confronting weighing load bearing plate are not mechanically joined. Below each weighing load bearing plate are load cells for emitting changes in signals representative of the weight of a load on the weighing load bearing plates. As the load advances toward the weighing load bearing plates, the ramps attenuate excessive forces and shock resulting from the load advancing onto the weighing load bearing plates. As a consequence thereof, the load cells are not subject to the excessive shocks or forces of an advancing load.

Abstract: This scale is primarily intended for the weighing of a hospital bed containing a patient. It may weigh an empty bed or any wheeled load. The scale is mounted on a frame which rests on the floor during a weighing operation, and is lifted off the floor onto a set of casters for moving the scale from one location to another. A detachable handle is provided for pulling the scale on its casters. The scale frame is oblong. The bed being weighed is supported on two channel-shaped rails, which are upwardly open. A pair of upwardly open, channel-shaped ramps are provided for rolling a bed onto the weighing rails from either side of the scale. The rails are provided with retractable blocking bars at both ends to prevent a bed from accidentally rolling off the rail. The ramps are removable. Provision is made for mounting the ramps on the scale during movement of the scale from one location to another.
