摘要： PROBLEM TO BE SOLVED: To provide a pipe clamp device capable of suppressing the misalignment of pipes in the longitudinal direction.SOLUTION: In the state that fixed pipes 20, 22 are held between a pipe supporting member 27 and a holding member 31, a bolt 35 is threaded to a screw hole 26B of a column member 26. Thus, a pipe clamp device 25 fixes the fixed pipes 20, 22 to a boom 12. The pipe supporting member 27 and the holding member 31 have flat parts 27A, 31A and semi-cylindrical parts 27B, 31B, and the semi-cylindrical parts 27B, 31B are formed with through-holes 28, 32, respectively. Thus, the semi-cylindrical parts 27B, 31B are formed with two end side edge portions 29, 33 located at both longitudinal end sides of the fixed pipes 20, 22 and two intermediate side edge portions 30, 34 located at the longitudinal intermediates of the fixed pipes 20, 22, respectively.

摘要： PROBLEM TO BE SOLVED: To solve the problem that a mechanical switching valve for controlling a hydraulic actuator is inferior in switching operability to an electromagnetic switching valve, because an easy and rapid switching operation can be hardly performed by using a handy switch etc. making an operating physical force small, though the mechanical switching valve enables the simplification of constitution of oil passage-switching control and a reduction in component cost in comparison with the electromagnetic switching valve. SOLUTION: This switching valve operating mechanism 110 includes: operation pistons 176 and 179 which are connected to a spool 145 of a switching valve 240 for PTO via an operation link 161; an electromagnetic valve 113 which hydraulically controls the reciprocation of the operation pistons 176 and 179; and a controller 123 which serves as a control device for transmitting an actuating signal to the electromagnetic valve 113. The control of the operation of the electromagnetic valve 113 makes the spool 145 moved via the operation pistons 176 and 179 and the operation link 161, and makes the switching valve 240 operated for switching.
