Title:
ARM FALLING MOTION CONTROLLER FOR WORKING VEHICLE
Document Type and Number:
Japanese Patent JP3808813
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To facilitate the release of contraction motion control of a rising and falling cylinder by an arm control member.
SOLUTION: The arm rising and falling motion controller 40 includes the vertically movable arm control member 41 pivoting one end thereof on an arm 21 and extending so as to cover the upper surface of the rising and falling cylinder 23, a lock pin 50 detachably inserted in the lower part of the front end of the arm control member 41 and a twisting coil spring 60 mounted to the upper part of the front end of the arm control member 41. When the rising and fall cylinder 23 makes extensile motion to abut the front end section of the arm control member 41 on the end face 23b1 on a rod side of a cylinder tube 23b, the contraction motion of the rising and fall cylinder 23 is controlled. Under such a condition, a first arm section 61 of the twisting coil spring 60 is abutted on the upper surface of the front end of the cylinder tube 23b, and when a second arm section 62 is interlocked with an locking pin 45 of the arm control member 41 to let the rising and fall cylinder 23 make extensile motion, the arm control member 41 is oscillated upward to release the contraction motion control of the rising and falling cylinder 23.
