    摘要： Provided is a construction machine in which a pair of boss parts (17L, 17R) coupled via a boss pipe (18) are welded to a tip end of an arm (7), a coupling pin (16) is rotatably supported in bushes (20L, 20R) of the respective boss parts (17L, 17R), and brackets (8b) of a bucket (8) are coupled to opposite ends of the coupling pin (16). An inner pipe (25) is fitted onto the coupling pin (16) on an inner circumferential side of the boss pipe (18), and defines a grease passage (26) between the coupling pin (16) and the inner pipe (25). Left and right gaps between the boss pipe (18) and the inner pipe (25) are closed with side plates (27L, 27R), and a pair of grease chambers (28L, 28R) communicating with each other via the grease passage (26) are defined. A grease supply pipe (29, 30) has a base end welded to a center of an outer circumferential surface of the inner pipe (25) in an axis (C) direction, and a tip end opened in a left side plate (7L) of the arm (7), so that a nipple (33) is mounted to the tip end.

    摘要： The invention relates to a linking device for coupling working equipment, such as a head for harvesting trees, to the end of a crane boom on a working machine, said end comprising crane ears, wherein the linking device comprises a linking device body that supports a first rotation shaft defining a first rotation axis and a second rotation shaft defining a second rotation axis that runs substantially transverse to the first rotation axis, wherein the linking device is intended to be suspended by the first rotation shaft between the crane ears for free rotation of the linking device around the first rotation axis on the crane boom, wherein the linking device comprises first braking means for braking the rotational movement of the linking device around the first rotation axis, wherein the first braking means are arranged to move at least one of the crane ears towards the other to clamp the linking device body between the crane ears.

    摘要： A pin clamp has a housing with a bore. A piston is coupled to a shaft, where the piston is in sliding engagement with the bore. The housing has first and second ports on opposing sides of the piston. A clamping arm coupled to the shaft extends and retracts with respect to the locating pin. A check valve is in the housing, where the check valve selectively maintains a pneumatic pressure on one of the first and second axial sides of the piston when pneumatic pressure is removed from the respective first or second axial side of the piston. One or more passages are further defined within the housing, defining a pneumatic circuit coupling the first port, second port, check valve, and a volume associated the bore. The check valve can be a pilot-operated check valve that is configured to be selectively energized by an application of pneumatic pressure.

    摘要： A pin joint assembly including a pin defining a longitudinal axis and having an end portion, a bushing coaxial with the pin about the longitudinal axis and having an end portion, and a collar engaging the end portion of the pin and having an inner portion in proximal relation to the end portion of the bushing and an outer portion in distal relation to the end portion of the bushing. The end portion of the bushing, the inner portion of the collar, and the pin cooperate to define a channel. The pin joint assembly further includes a thrust ring coaxial with the pin about the longitudinal axis and residing in the channel in spaced-apart relation to the bushing.
