摘要： PROBLEM TO BE SOLVED: To linearly move a hand provided on an arm simply by oscillating the arm by means of a cam mechanism, and simplify the construction. SOLUTION: The intermediate part of one link 28 of a parallel link constituting an oscillating arm 20 is pivoted on the tip part of a driving arm 14 through a sliding pin 18. The sliding pin 18 is passed through a long hole 16 formed in the driving arm 14 to be inserted in a parabolic can groove provided on a base plate 70. When the driving arm 14 is oscillated as indicated by the arrows 24 by a driving motor 82, the sliding pin 18 excutes a parabolic motion along the cam groove 22, the oscillating arm 20 oscillates around the lower pivoting point, the lower end part of the oscillating arm 20 moves up and down along a guide 40, and a hand 36 mounted to the upper end part of the oscillating arm 20 is linearly reciprocated in the horizontal direction.

摘要： PROBLEM TO BE SOLVED: To stabilize crushing reaction by holding the pushing-in thrust of a breaker to a substance to be crushed at set pressure, interrupting an oil passage by the differential pressure of the primary-side pressure and secondary-side pressure of a push-in cylinder and obstructing the sudden change of the push-in movement of the breaker. SOLUTION: A breaker 40 is supplied with a hydraulic fluid and crushing thrust is given by a push-in cylinder 24, and pushing-in thrust supplies the head- side oil pressure chamber 44 of the cylinder 24 with oil pressure. Supply pressure to the cylinder 24 is adjusted at set pressure through a balancing valve 50 in the supply of oil pressure at that time, and works so as to give constant pushing-in thrust to the breaker 40. Consequently, the pushing-in reaction of the breaker 40 is received by crusher itself, and reaction is held constant and the stability of operation is ensured even when the crusher is loaded on a small- sized construction equipment. When a differential-pressure driving valve 60 is disposed on the outlet side of a rod-side oil pressure chamber 56, a discharge oil passage 58 is interrupted at front-rear differential pressure and an object is punched by a chisel 42, the crusher is shut down automatically at the time of emergency. Accordingly, the safety of crushing operation can be improved.

摘要： PURPOSE:To synchronize the claws of forks with each other to be able to approach and separate from each other, and directly hold a heavy cargo such as steel material by arranging post parts of a pair of the forks in parallel, and providing pinions simultaneously engaging with both racks formed on the facing parts of both the posts on the mounting base plates. CONSTITUTION:In this holding device 100, a pair of forks 104, 106 facing each other at the top and bottom of the device, are arranged on a fixed frame 102 mounted on a turning drive part, and racks 104R, 106R are formed on the facing parts of post parts 104P, 106P which face each other on each side of the respective forks 104, 106. Further, pinions 112 simultaneously engaging with the racks 104R, 106R are mounted to the fixed frame 102. Thus, lowering/raising of one fork 104 or 106 by the operation of a pair of holding cylinders 114 provided on the back face side of the fixed frame 102 is transmitted to the other through the pinions 112, and steel, etc., are held by approaching/separating actions of both the forks 104, 106.
