    摘要: The gas circuit breaker has a configuration such that a stationary contact section and a movable contact section are arranged in an arc-extinguishing gas sealed container, to face each other, and the movable contact section includes a hollow operating rod having an exhaust hole at its rear portion, a movable cylinder arranged around the rod, a hollow movable arc contact provided on the movable cylinder and an insulating nozzle surrounding the movable arc contact. The movable contact section further includes a stationary piston portion insertable/removable inside the movable cylinder, and the space formed by the movable cylinder and the current collecting cylinder fixed to the stationary piston portion is partitioned by a parting plate into a thermal pressure elevation room space at front side and a compression room space at rear side. During the electrode opening operation, the compression room space is compressed by the interaction between the movable cylinder and the piston portion, thus increasing the pressure in the space, and the speed of the movement of the operating rod is slowed down just before the completion of the electrode opening operation.

    摘要: To provide a cab supporting structure capable of supplying a protection function with a simple configuration by using an attenuation mechanism commonly used for a controlled vehicle for protecting the cab or an operator from high impact force acting on the cab while absorbing vibration and shock on the cab in a normal condition when a construction machine falls down. The cab supporting structure is provided with an attenuation mechanism elastically supporting a cab against a frame. A regulation member, only when certain displacement is generated in the cabin the extension direction of the attenuation mechanism, regulating this displacement is provided separately from this attenuation mechanism. The regulation member regulates the displacement of the cab before a stroke end of the attenuation mechanism. Upon arranging a work equipment on the frame, the regulation member is provided at least at the opposite side of the work equipment.

    摘要: A lock system is made in a combination of a rotatable latch and a release lever for restricting the turn of the latch in a disengaging direction. The lock system further includes a release lever disengagement maintaining mechanism which engages with the release lever to maintain it in its disengaging condition wherein the latch is disengaged from the release lever. The release lever disengagement maintaining mechanism is designed to release the release lever from its disengaging condition when the latch turns through a specified rotation angle. Lock mechanisms are provided for a lift open type window which can be housed by moving a movable window frame upward from a window closing upright position, being guided by a pair of guide rails. The lock mechanisms are respectively attached to both ends of a top part of the window frame, so as to be exterior to the window frame and interior to and under the guide rails. Each lock mechanism has a turnable latch having two engagement notches at positions which are a specified rotation angle displaced from each other and a release lever for restricting the turn of the latch and for disengaging the latch. There are also provided strikers at the upper part of a window frame's home position where the window frame stands up and at the end of a window housing position. These strikers are respectively attached to a support structure so as to be parallel with the axis of rotation of the latch, and respectively come into engagement with their corresponding engagement notches of the latch to hold the window frame.
