Patent number: 6019569Abstract: A swing type front working mechanism 7 is provided, the front working mechanism 7 having a foot portion of a lower boom 8L of a boom 8 pivotally supported on brackets 12a through a pin 18. A cross-link 40 is connected between the bracket 12a and an upper boom 8U by pins 41 and 42 only along the right lateral side of the boom 8, and no cross-link is provided on the side of an operator's cab 6. In the case of a singular cross-link arrangement of this sort, the boom 8 could be operated under biased load distribution, and therefore the lower boom 8L is likely to be subjected to greater stresses or greater lateral bending stresses on the side of the cross-link 40. A boom operating hydraulic cylinder 43 is located in a position which is shifted aside from a center axis A1 of the lower boom 8L in a direction away from the operator's cab 6, thereby forming a lateral load buffer as a counter measure which suppresses or buffers lateral bending stresses of the sort as mentioned above.Type: GrantFiled: September 30, 1997Date of Patent: February 1, 2000Assignee: Hitachi Construction Machinery Co., Ltd.Inventor: Nobumitsu Sakuma

Patent number: 4618005Abstract: An apparatus for attachment to a vehicle, preferably a bulldozer, comprises a first arm having a ripper shank extending therefrom which is pivotally attached to a second arm. A second arm is mounted to a vehicle for rotation about a horizontal axis so that when the first and second arms are in one orientation the ripper shank may be operated to move in a plane transverse to the direction of motion of the vehicle. The apparatus may be rotated to any angle such that the shank extends forwardly, or rearwardly, of the vehicle to engage objects. In the preferred embodiment, the first and second arms are pivotally mounted to a journal which extends through a mounting housing. A hydraulic cylinder engages one end of the journal at an eccentric location to cause the journal to rotate upon activation of the hydraulic cylinder.Type: GrantFiled: August 20, 1984Date of Patent: October 21, 1986Inventor: Douglass G.

Patent number: 4318445Abstract: An implement side shift assembly is disclosed for laterally shifting an earth-working implement relative to a tractor or the like. The side shift assembly includes a frame assembly having laterally extending upper and lower slide rails. An implement support bracket mounts the implement to the slide rails for lateral movement. A slide plate is slidably mounted between the slide rails for lateral movement, and a piston-cylinder is connected between the frame assembly and slide plate to move the slide plate laterally. A latching mechanism mounted on the implement support bracket selectively connects the slide plate to the implement support bracket at one of a plurality of connecting points on the slide plate. One of the features of the invention resides in attaching lift cylinders to the side shift frame assembly at positions as far outboard as possible on the opposite ends of the frame assembly to reduce the bending and twisting moments on the frame induced by the implement.Type: GrantFiled: August 18, 1980Date of Patent: March 9, 1982Assignee: J.

Patent number: 4261684Abstract: A device for mounting an appliance (such as a backhoe excavator) on a vehicle (such as a tractor) comprises a fixed frame secured to the vehicle, and a movable frame to which the appliance is pivotally connected by means of a kingpost. The movable frame has elements thereon which are slidable along respective linear guides on the fixed frame, thereby enabling the movable frame to be pivoted relative to the fixed frame under the control of a drive so as to offset the kingpost from the center line of the vehicle. The guides converge at a predetermined angle rearwardly of the vehicle, and the elements subtend the same angle to the kingpost so that the kingpost moves along a straight line at right angles to the vehicle center line as the movable frame is pivoted with respect to the fixed frame. This arrangement enables the appliance to be pivoted relative to the vehicle about a comparatively large angle without fouling the rear (particularly the rear wheels) of the vehicle.Type: GrantFiled: February 27, 1979Date of Patent: April 14, 1981Assignee: F.
