Abstract:
A control circuit (400, 500) for an attachment mounting device (29) that has a closed position for securing an implement (36) and an opened position for releasing an implement (36). The control circuit (400, 500) includes at least one hydraulic actuator (402, 403, 502, 503), a control valve (408, 508) and an auto-close feature (428, 528). The control valve (408, 508) has at least a first energized position (413, 513) and a second energized position (415, 515). The first energized position (413, 513) applies pressurized fluid to the at least one hydraulic actuator (402, 403, 502, 503) to actuate the attachment mounting device (29)\ into the closed position. The second energized position (415, 515) applies pressurized fluid to the at least one hydraulic actuator (402, 403, 502, 503) to actuate the attachment mounting device (29) into the opened position. The auto-close feature (428, 528) is configured to be activated after the control valve (408, 508) is in the first energized position (413, 513) and is configured to be deactivated after the control valve(408, 508) is in the second energized position (415, 515).
Abstract:
The fundamental principle of the invention is that when a tool A is removed from a loader and an attachment arrangement 1 that belongs to it, parts of the attachment arrangement 1 are arranged in a position such that the attachment arrangement 1 is automatically placed into a locked position when a tool A is again mounted, or a second tool, when the tool A is placed in the correct position in contact with the attachment arrangement 1. The invention concerns an arrangement (1 ) for a loader that makes it possible to attach a tool (A) to the loader. The arrangement (1) comprises a locking arrangement (9) for determining the position of the tool (A) and locking it to the arrangement (1 ) in this position, and a safety arrangement (14) that ensures that the locking arrangement (9) takes up its locking position only when a tool (A) is correctly arranged at the attachment arrangement (1). The arrangement (1 ) is characterised by a part (17) that functions independently of the locking arrangement (14) and that can retain the locking arrangement (9) in an open position that does not perform the locking function, and a releasing part (18) that releases the locking arrangement (9) from the retaining part (17). The invention concerns also a method to be used when a tool (A) is to be removed from a loader in which the loader comprises an arrangement (1) according to the invention and a method to be used when a tool (A) is to be attached to a loader in which the loader comprises an arrangement (1 ) according to the invention.
Abstract:
A coupling device or "quick coupler" which permits the rapid connecting and disconnecting of implements (120) to a hoe boom (113) comprising at least one primary lifting arm (113) fitted for a hinge pin (122) and a "curling linkage" mechanism (115). The quick coupler having a housing (250), which can be temporarily attached to the hoe boom (113) using the hinge and link pins (121, 122) or can be built into the hoe boom (113) itself, and which contains means for attaching the coupling device (261, 270) to a variety of implements. The effective operating distance of the connector can be adjusted so that the coupler can be used with various implements.
Abstract:
A quick release hitch for attachment to the arm of an excavator comprises a body (1) having a swinging plate (2) and a locking cam (3) for locking the plate in a closed position. The hitch attaches to the excavator arm by bushings (13, 14) and (40, 41). Pivot pins (60, 61) on a bucket (62) are embraced by jaws (23, 33). The cam is operated by handle (53) to open and close rear jaw (33) which cooperates with beak (42) to grasp the rear pivot pin.
Abstract:
Die Erfindung betrifft einen Schnellwechsler (10) mit zumindest einem Riegelbolzen (26) und einem motorischen Antrieb, der den Riegelbolzen (26) in eine Verriegelungsposition und eine Entriegelungsposition verfährt, wobei der Antrieb (16) einen Energieanschluss (28a,28b) und mit dem Riegelbolzen (26) zusammenwirkende Abtriebsmittel (34) aufweist, wobei der Antrieb (16) einen Drehantrieb (30) aufweisend einen Motor und eine Abtriebswelle (34) umfasst, wobei die Abtriebswelle (34) mechanisch mit dem Riegelbolzen (26) verbunden ist, so dass der Riegelbolzen (26) entlang einer Betätigungsachse verfahrbar ist. Die Erfindung zeichnet sich dadurch aus, dass der Antrieb (16) einen Ansatz (20) für eine Welle-Nabe-Verbindung aufweist, an dem ein Werkzeug zur manuellen Betätigung anbringbar ist, so dass eine manuelle Betätigung direkt auf die Antriebswelle (34) wirkt und dabei der Ansatz (20) koaxial zu einem Drehanschluss (32a, 32b) einer Getriebewelle (32c,32d) angeordnet ist.
Abstract:
An attachment for the rear of a skid steer type vehicle to connect any of a variety of commercially available attachments to the rear of that vehicle. Hydraulic actuators articulate the arm assembly relative to the plate assemblies affixed to the vehicle to raise and lower the attachment. A second hydraulic actuator tilts the attachment forward and back.
Abstract:
A coupler used for the attachment of a work tool / implement to earth moving equipment. The coupler includes a locking mechanism (10) to prevent or restrict rotational movement of an actuator element R of the coupler. The locking mechanism (10) includes an engagement element (19) that is biased into engagement with one of a plurality of spaced apart engagement areas (12). The engagement element (19) can thereby engage with an engagement area (12) and be held therewith when the actuator element R is rotatably adjusted to attach the coupler to a work tool / implement.
Abstract:
Disclosed is an interface (302) for an implement that is to be operably coupled to a power machine (100). In one embodiment, a disclosed implement carrier (130; 200) is mountable to a power machine for securing an implement for use with the power machine. The implement carrier includes an implement carrier frame (202), a locking feature (220; 320) for securing an implement, and a coupler block (210; 500) that is pivotally mounted to the implement carrier frame for engaging couplers on the implement.
