Claims

[Scope of utility model registration request]

(1) A clamp device that is attached to an arm or boom of a construction machine, including a fork bracket that is removably attached to the tip side of the arm or boom, and a fork bracket that is rotatably supported on the base end of the bracket. a pair of forks that can be opened and closed; a link element for interlocking one of the forks with a hydraulic cylinder normally provided in the construction machine; Gear elements that mesh with each other around the shaft support, and when one of the forks operates via the link element due to the expansion and contraction operation of the hydraulic cylinder, the other fork responds in a related manner to open and close the forks simultaneously. A clamp device for construction machinery characterized by a configuration consisting of.

(2) The clamping device for construction machinery according to claim 1, wherein the hydraulic cylinder is a cylinder for a backhoe bucket that is permanently installed on the arm or boom.

(3) The link element consists of a bracket-side link whose base end is rotatably connected to the bracket with a pin, and a fork-side link whose base end is rotatably connected to one fork with a pin. The clamping device for construction machinery according to claim 1, wherein the distal end side is removably coaxially connected to the operating end of the hydraulic cylinder.

(4) Utility model registration claim 1 or 2, characterized in that the link element is such that the link connection position with respect to the bracket can be selectively changed so as to change the opening/closing angle of both forks. is a clamping device for construction machinery as described in item 3.
