Abstract:
A seafloor bulk mining tool for production cutting of a seafloor bench. The tool uses a tracked locomotion system to travel across a seafloor bench. Power and control interfaces receive power and control signals from a surface source. The tool has a drum cutter for cutting the bench, and a sizing grill adjacent the drum cutter for sizing cuttings as they are produced by the drum cutter. A drum shroud may also be provided to help contain cuttings. A suction inlet can be used to capture cuttings as they are produced, for example in conjunction with a spade and augers.
Abstract:
A radiator (152) of a cooling system is disposed within an engine compartment (140), between a rear mounted engine (144) and a cab (122) on a wheeled machine (99). The remaining components within the engine compartment (140) are arranged such that they are lower in height than the radiator (152), the engine compartment (140) enclosure (138) generally angling down from the cab (122) rearward. The enclosure (138) includes an air intake (190) that opens into a gap (188) between the enclosure (138) and cab (122). A fan (154) disposed rearward the radiator (152) may pull cooling air through the air intake (190) and past the radiator (152).
Abstract:
The invention refers to a multi-purpose working device (100), in particular, for producing flat surfaces, comprising a rear frame (200), a front frame (300), a central frame (400) connecting the rear to the front frame, whereas the central frame comprises at least one fixed part (410), being connected to the rear frame such that it is pivotable with respect to the rear frame around an axis, and a further part (420), being movable against this fixed part, so that the further part is mainly movable along the longitudinal axis against the fixed part in an adjustable way, preferably by hydraulic control means, whereas the front frame comprises one wheel (350) which is self driven, preferably by a hydrostatic drive (360), and whereas the multi purpose working device comprises a tool holder (500), connected by connection means (550) and controlled by control means (560) with the fixed part of the central frame, preferably for accommodating a shield (580), so that the tool holder is pivotable mainly perpendicular to the longitudinal axis and mainly parallel to the surface against the central part and is, in addition, movable to the side via a moving device, whereas the rear wheels (250) are driven by a hydraulic, preferably a hydrostatic, drive also so that they are not friction locked to each other via a fixed axis.
Abstract:
Ein Planiergerät (100) weist einen Grundrahmen (1) auf, der Dreipunktanschlüsse (10,15) zum Anschliessen an eine Dreipunktaufhängung (30) eines Schleppers (20) hat und an dem wenigstens eine Hauptschar (4) zur Bodenplanie angeordnet ist. Die Dreipunkt -Anschlüsse (10, 15) sind für eine von Wippbewegungen des Schleppers (20) abgekoppelte Verbindung ausgebildet. Die Hauptschar (4) ist schräg zur Fahrtrichtung (Pf1) angeordnet für einen Materialabtrag und Transport von Material von einem Randbereich des zu planierenden Wegs zu dessen Mittelbereich oder zu dem gegenüber liegenden Randbereich. Am vorderen Ende des Planiergeräts (100) ist ein Stützfuß (21) mit einer Boden-Auflageplatte (22) sowie einer in Fahrtrichtung davor angeordneten Räumplatte (23) und am hinteren Ende des Planiergeräts (100) ist eine Gleitauflage (2) als Boden-Abstützung vorgesehen.
Abstract:
A hitch assembly (1) commonly used between an accessory (such as a front end bucket) and a tractor or prime mover (such as a skid steer loader). The hitch assembly (1) includes a bearing arrangement, partly integral with one of two frame members (2, 3), which allows the two frame members (2,3) to rotate relative to one another. The two frame members (2, 3) are attached to the tractor via adaptor (61) and the rear of the accessory (eg bucket 60). The bearing portion thus enables rotation of the accessory (60) about an axis substantially parallel to the longitudinal axis of the tractor. Automatic control in conjunction with laser type levelling systems or GPS contouring of sloped surfaces is also possible.
Abstract:
A method of steering a vehicle (28) along a predetermined or real time path by using a steering control algorithm (16). The vehicle (28) includes a navigation system (13) and a navigation antenna (12). The navigation antenna (12) is mounted on the vehicle (28) at an optimum antenna position, whereas the steering control algorithm (16) assumes a nominal antenna position at a predetermined reference point. The method comprises the following steps: (A) obtaining a set of positioning data of the vehicle (28) by using the navigation system (13) and by using the navigation antenna (12) mounted at the optimum antenna position; (B) modifying the set of positioning data of the vehicle (28); (C) measuring a steering angle(s) of the front wheels of the vehicle (28) relative to a predetermined reference direction(s); (D) calculating a correction(s) to the measured steering angle(s); and (E) performing a steering action by using the correction(s) to the measured steering angle(s) to move the vehicle along the predetermined or real time path.
Abstract:
An attachment for treating soil-like material and for attachment to a tractor or skid steer vehicle having a frame with inwardly inclined transporting elements for distributing the material being treated.
Abstract:
The invention relates to a hydraulic actuator (3) with a casing (10), a piston (12) which is movable in the casing and divides it into a first chamber (18) and a second chamber (16), and a piston rod (14) fixedly connected with the piston (12). Moreover the piston is movable towards an abutment surface (30) which is adapted to take up, against spring action, part of the weight of the appliance when the appliance (2) is in the second lowered position. Preferably the actuator has a second piston (22) which runs along the piston rod (14) and which is adapted to divide the first chamber into a third chamber (18a) and a fourth chamber (18b), a surface of said second piston facing the first piston constituting said abutment surface (30). The actuator is intended to be used to operate a vertically adjustable appliance which is mounted on a vehicle.
Abstract:
An accessory (1) that can be attached to any of a variety of heavy machinery such as bulldozers, backhoes, tractors, etc, is used for a final grading and leveling pass and is comprised of, a grating (1) having a lattice (2, 3) arrangement with a "V" pattern and a set of springs (9) disposed at each side of a hydraulic piston (6) which controls the level of the grating.
