Load transferring apparatus comprises a base member, a planar platform for supporting a load and a drive arm pivotally mounted on the base member for moving the platform in plane between a retracted position at which the platform assumes a first orientation and an extended position at which the platform assumes a second angularly transposed orientation while remaining substantially in the plane occupied when in the retracted position. The drive arm is fixed to a drive arm shaft which, in turn, i...

A load hook intended to be attached to the outer end of a crane jib, a crane wire or corresponding device. According to the invention, the load hook (1) comprises two opposed hooks (2,3) connected to and extending in spaced parallel relationship with each other, where each hook comprises a substantially U-shaped portion (4,5) forming a U-shaped groove (6,7) intended to support a carrying member connected to a load.

In a load cell, in particular for weighing systems, comprising a deformable member (1), this deformable member has an aperture (2) extending transversely of the direction of the force, which is closed by at least one disc-shaped wall which corresponds to the cross-section of the aperture and extends transversely of the axis of the aperture and serves to receive strain gauges which are deposited by means of a film technique. The deformable member is formed by two sub-members (3, 4) which are weld...

A load indicator partly collapses under a predetermined compressive load to provide visual and tactile indications that such predetermined load has been reached or exceeded. The indicator has a longitudinal axis, opposite ends, an outer surface and a central cylindrical hole opening outwardly at the opposite ends. A circumferential groove in the outer surface intermediate the ends divides the indicator into first and second integral parts that move toward one another under a predetermined compre...

A load balancer adapted to set the load of an article to substantially zero by utilizing an air pressure, and provided with a balance cylinder unit consisting of air brakes, a balance cylinder and a weight sensing cylinder. This balance cylinder unit is formed by arranging the balance cylinder and weight sensing cylinder on the same axis, and air brakes on both sides of the balance cylinder.

For indicating when the tension in a bolt reaches a predetermined value, there is provided an electrical contact (24) which is held in a position adjacent to an axially facing surface (20) of the bolt and in a fixed position relative to a remote part of the bolt. Tightening of the bolt reduces the clearance between the contact and the surface of the bolt. When the clearance is eliminated, a bulb (27) is illuminated.

A load carrier which is made from a tough and bendable material, includes a bottom member that has a predetermined number of sides and a plurality of side walls that are mounted on the bottom member and cooperatively define a surrounding wall. Each of the side walls has a lower portion wrapped around the respective side of the bottom member in such a manner that the side wall is pivotable relative to the latter. Each of the side walls has a first fastening piece mounted on one side thereof and w...

The invention is a load cell for the measurement of force, independent of displacement, created by means such as weight, acceleration, pressure, and the like. The load cell has a beam structure with beams positioned parallel to each other in at least one plane. Generally, these parallel beams are attached to a stationary substrate and have sensing means attached between the two beams. In operation, deflection of one beam creates a response in the sensing means due to the relative action or defle...

A digital load cell includes a rocker pin, guided beam, torsion ring or other counterforce, a circuit board mounted on the counterforce and an enclosure sealing the circuit board and all but the load bearing surfaces of the counterforce. The circuit board includes an A/D converter and a microcomputer. Digital communication is provided with the circuit board through a connector mounted on the enclosure. Weight data are corrected digitally. The load cell may be calibrated, characterized, controlle...

A load cell comprises a block with a recess in an upper rectangular surface thereof. A plate overlies the upper surface and is parallel thereto and spaced therefrom by a spacer interconnecting the block and the plate at one end of the plate so the remainder of the plate can deform on application of a load to an upper surface thereof. The position of application can be adjusted along the length of the plate. Damage to the plate is avoided on application of an excessive load by its engagement with...
