摘要:
A linkage system (12) connects an equipment (11) and an excavator or a basic machine (10) by which such linkage is carried. The linkage is quadrilateral so as to translate said equipment (11) parallely to itself and it consists of at least one rigid element (13) connecting the machine (10) and the equipment (11) and at least one piston actuator (15) for said rigid element (13). The elements forming the linkage system (13,14,15,40) or part of them are connected with the machine (10) by no more than two separate and substantially parallel hinge axles (22,23).

Ein Kupplungsrahmen (30) zur Aufnahme eines Arbeitswerkzeuges ist an einer Schwinge eines Arbeitsfahrzeuges um eine horizontale Querachse (138) verkippbar angelenkt und weist zwei seitliche Tragstützen auf, die das Arbeitswerkzeug aufnehmen und über ein Querrohr (29) miteinander verbunden sind, wobei das Querrohr (29) koaxial zur Querachse angeordnet und an den Tragstützen derart befestigt ist, daß eine begrenzte Relativbewegung der Tragstützen zueinander möglich ist.
摘要:
A backhoe is mounted to a rear portion of a loader by means of a locking sideshift mount The sideshift mount includes a main frame (34) fixedly mounted to the loader, and a slide frame (36) which is slidably mounted to the main frame (34) for transverse movement between the left and right sides of the loader. A pair of locking apertures (66) open downwardly from a lower surface of the slide frame (36). A pair of stabilizers (44L, 44R) are mounted to the rear portion of the loader adjacent the left and right sides of the main frame (34). Locking pins (68L, 68R) on the stabilizers (44L, 44R) extend upward and are cooperable with the locking apertures (66). When the slide frame (36) and backhoe are positioned on the left or right side of the main frame (34), and the stabilizers (44L, 44R) retracted by hydraulic cylinders (64), the locking pins (68L, 68R) will engage the slide frame (36) and prevent movement of the backhoe (12).

An articulated arm-type machine (10), such as an excavator, has a boom (30) articulated for motion in a generally vertical arc, a stick (40) articulated onto the distal end of the boom, and a tool mounted at the distal end of the stick. The stick is connected to the boom by a quick-disconnect shoe (36) that is rockably mounted at the distal end of the boom and a mating fitting mounted at the distal end of the boom and a mating fitting mounted at the proximal end of the stick. A pair of grab hooks on the shoe are used to pick up the stick fitting by hooking onto a grab pin mounted thereon. A set of gear tooth racks on the quick-disconnect shoe intermesh with a corresponding set of gear tooth racks on the stick fitting, and these eliminate play between the stick and boom.

A backhoe (12) having a scoop (14) adapted to be rotated about a horizontal axis (64). A turntable group (24) disposed between the backhoe group (12) and the chassis (10) of the backhoe permits the rotation of the scoop. In particular by rotating the scoop (14) substantially parallel to the ground, the scoop may be used to remove material from underneath a structure.

On décrit une pelle motorisée portative comportant un cadre équipé d'un bras articulé, supportant un moteur et muni de mancherons, et est caractérisée en ce que ledit bras articulé consiste en une perche (5) solidaire dudit cadre (3) et en un manche de pelle (13) articulé sur l'extrémité libre (15) de ladite perche (5), une extrémité dudit manche (15) étant équipée d'une palette (17) basculable et l'autre extrémité du manche (13) s'étendant au-delà de l'articulation (15) sur la perche (5) étant articulée sur un écrou (21) déplaçable sur une vis sans fin (23) actionnée par ledit moteur (25).
摘要:
A loader (20) has a mast (22) which is releasably attachable to the front end of a tractor (10) by forward and rearward mounting structures (34, 26, 34a). These forward mounting structures comprise mounts (62, 62a) on the tractor (10) and mounts (84, 148) on the mast (22) which come into engagement on the mast (22) being swung upwardly about the rearward mounting structures (26). The associated mounts (62, 84 and 62a, 148) have co-operating guide faces which direct the mast mounts (84, 148) into abutment with a stop (68, 180) on the tractor mounts (62, 62a) which limits upward movement. The mast (22) is prevented from downward swinging movement by a cam in the form of an eccentric cylinder (110, 110a) arranged on either mast mount (84, 148). The cam (110, 110a) can be turned to engage a cavity (78, 78a) in the associated tractor mount (62, 62a) to stop such movement. The mast mounts (84, 148) include a parking stand (36, 36a) and are detachable from the mast (22). The loader can then easily be marketed with or without the locking feature and the parking stand (36, 36a).
