A fluid flow from the hydraulic consumer (10) with higher pressure loading via the flow divider (26) to the hydraulic consumer (12) with lower pressure loading can be suppressed by one shut-off device (38) arranged between the flow divider (26) and at least one hydraulic consumer (12). The shut-off device (38) is arranged in a fluidic connection (F2) from the flow divider (26) to the hydraulic consumer (12) with lower pressure loading.

Abstract: An attachment used in conjunction with a backhoe or track hoe to convert it into a machine to unload ties off of railroad cars. Two pins on an upper end of the attachment secure it to the distal end of the working arm of the backhoe or track hoe so that a front edge of the attachment point toward the backhoe or track hoe. Upper ends of four c-shaped members attached to an upper plate on the upper end of the attachment. Opposite lower ends of each of the four spaced apart c-shaped members are flattened on upper and lower surfaces into a point. A lower plate is secured to the upper surfaces of the lower ends of the c-shaped members to form the front edge. Support bars secure between adjacent c-shaped members and openings are provided in the c-shaped members to reduce weight while maintaining strength.

Abstract: Actuator mechanism for a two-bucket grab device and having two grab arms arranged to move as pincers with respect to one another, has two hydraulic pivot motors with journals of the respective pivot shafts projecting from the motor housing and supporting the grab arms. Each of the pivot motors has a cylindrical tubular piece provided with an internal thread designed to engage an external thread on the respective pivot shaft. The tubular piece is a ring piston axially-displaceably, but non-rotatably held in a cylinder space formed in one of the respective bucket housings. Pitch of the threads is sufficiently large for the ring piston to transmit required torque to the respective pivot shaft by axial displacement of the ring piston. The displacement path of the ring piston between two annular cylinder chambers corresponding to high and low pressure chambers which can be loaded with hydraulic oil, corresponds to the desired pivot angle of the two arms of the grab bucket.

Abstract: A method of excavating a surface layer of soil is disclosed that uses an excavator with a grab having two bucket halves with cutting edge. In a first excavating position, the grab is held in a first orientation as seen in projection on a horizontal plane and inserted into the layer of soil in an open position of the bucket halves until their cutting edges reach a first predetermined level while maintaining the first orientation. While maintaining that level and first orientation, the bucket halves are moved to a closed position during which movement their cutting edges move towards each other through a substantially straight path so as to excavate a first rectangular portion of the layer of soil. The grab is then lifted and moved to a discharge position horizontally spaced from the excavating position and emptied there to make further transport of the excavated soil possible.

Abstract: A unit for the collection, cleaning and calibration of electrolysis pots and, in particular, of anodic orifices thereof, as the anodes of an installation for the production of aluminum by igneous electrolysis are replaced, includes two buckets hinge-mounted at the level of a lower end of a shovel-bearing chassis which is vertically movable. The lower edge of each of the buckets is movable in a circular direction by a connecting rod assembly. Also the shovel-bearing chassis is joined to a vertical guide mast and is mechanically linked to the buckets-supporting chassis. The buckets-supporting chassis is moveable relative to the shovel-bearing chassis and integrates the connecting rod assembly for closing and opening the buckets with the buckets being hinge-mounted at the lower end of the buckets-supporting chassis.

Abstract: A hydraulic system for a utility vehicle includes provision for controlling two hydraulic implements or tools alternately with a single control lever. The hydraulic system includes a first hydraulic implement and a second hydraulic implement both hydraulically flow-connected to a diverter valve. A source of pressurized hydraulic fluid is connected to a selective control valve, operated by a control lever, and the selective control valve is hydraulically flow-connected to the diverter valve. The diverter valve is selectively operated to connect the control valve to either the first or to the second hydraulic implements. An implement-select actuator is signal-connected to the diverter valve and configured for alternately operating the first and second hydraulic implements.

Abstract: A drive apparatus for a grab device comprising two grab arms, which can be moved like pincers, preferably for a two bucket grab, consists of two hydraulic pivot motors whose shaft journals of the pivot shaft projecting over the motor housing carry the grab arms. Each of the pivot motors has a cylindrical tube piece which is provided at its inner wall with a section which is provided with an internal thread and which is in engagement with a section of the pivot shaft provided with an external thread. The tube piece is a ring piston axially displaceable in but held non-rotatably in a cylinder space formed in one of the housings. The pitch of the threads is so large that the ring piston is able to give the pivot shafts the required torque by its axial displacement. The displacement path of the ring piston between the two annular cylinder chambers, which are alternatively high and low pressure chambers which can be loaded with hydraulic oil, corresponds to the desired pivot angle of the two buckets.

Abstract: A clam bucket of a type designed to attach by way of a pin (20) through vertical lugs (92) to the stick of an excavator making the attachment process fairly simple. These vertical lugs (92) are part of the rotational housing (32) assembly which, in conjunction with a rotational mounting plate (22) at the top of a square tubing extension (48) enable the bucket (70) to make a full 360° turn. The bucket (70) halves are each powered by a hydraulic cylinder (56), the lines of which attach to excavator controls. The clean-out system is a pair of wiper plates (86) incorporated into the bucket (70) halves. These wiper plates (86) sweep the bucket (70) halves each time the bucket opens and closes preventing buildup of material. This self-cleaning hydraulic clam bucket can be manufactured in size to suit the consumer.

Abstract: A device for transplanting trees or bushes having at least two spades that can be adjusted against each other. These spades can be set between an open and closed position by means of a pair of attached servo-drives. When in the open position, the spades are removed from each other by a space corresponding at least with a diameter of the tree or the bush to be transplanted. When the spades are in their closed position, they complement each other, forming a partial spherical cup. To reduce the resistance of the spades as they penetrate the soil, the cutting blade of the spade has the shape of a corrugated ground edging. These corrugated ground edges have alternating elevations and recesses, whereby the elevations of the cutting blade provide sufficient stability and safety against breakage. The ground surfaces that oppose each other on these spades are disposed on alternating sides to allow the cutting blades to overlap.

Abstract: This apparatus is a tongs-like, load-lifting device for automatically loading and unloading objects and liquids, comprising two elongated numbers pivoted at a selected distance from the apparatus' top with a main pivot pin. Its lower portions are essentially vertical, and may have perforations, to hold in place either a retrieved object or liquids, when pivoted, hemispheric buckets are included. Two hammerheads, mounted at ends of horizontal bars, located on apparatus' upper portions, are provided with magnets to either attract or repel each other. One head may have an electromagnet and the other a permanent magnet, or both heads may have electromagnets. The bottoms of apparatus' lower portions have pivoted extensions to help support the load. The two extensions are held up by either springs or stretchable bands, so their ends would not injure a person. The extensions are pushed down by the person or the object entering the apparatus.
