摘要:
In a construction machine such as a hydraulic excavator in which a boom of a working attachment is arranged to one of the left and right sides of a cab into which an operator gets on, a load transmission member for transmitting a lateral load imposed on the cab at the time of rollover of a machine main body to the boom serving as a load receiving member is attached to a side surface of the boom in a state that the load transmission member is elastically deformable taking a boom attachment point as a supporting point, further, a projection piece is provided for this load transmission member, and a clearance is formed between this projection piece and a left end surface of a top plate of the boom.

A reinforced structure for a cabin of a working machine is disclosed, which comprises a cabin, a boom installed along the cabin, and a reinforcing member provided for the cabin. The cabin includes front pillars, upper pillars and rear pillars. The reinforcing member includes a first member located longitudinally between upper ends of the front and rear pillars located on the working apparatus side of the cabin, the first member being fixed to the upper pillar located on the same side, and a second member, one end of the second member being fixed to an intermediate position of the first member, and the other end thereof being fixed to the other upper pillar.

A rear beam has a first beam with right and left ends welded to right and left rear supports and a second beam welded to a front surface of the first beam along the right and left direction. The second beam is welded to the first beam so that an upper end portion of the second beam is above an upper end portion of the first beam and a lower end portion of the second beam is above a lower end portion of the first beam.

Provided is a construction machine. The construction machine is provided with a lower propelling body and an upper slewing body. The upper slewing body has an upper frame, a cab disposed on a left portion or a right portion of the upper frame, and cab mounts. The cab mounts are disposed at lateral ends on each of front and rear portions of the cab respectively, including, on at least one of the front and rear portions, first and second outer-side cab mounts disposed at the outer side of lateral ends of the cab. The first and second outer-side cab mounts are juxtaposed with a small enough distance to receive a rollover load concurrently when the construction machine rolls over toward a side of the cab.

A construction machine has a locking mechanism for locking a lower end of a front part of a guard member onto a bracket while allowing a cab to be moved with elastic deformation of an anti-vibration mount. The locking mechanism has a shaft body across the bracket and the guard member vertically movably with the guard member. The shaft body has a stopper to be engaged to an upper frame side to restrict a moving amount of the shaft body to a stroke for shock absorbing. The bracket has a bolt insertion hole for a bolt to fix the bracket and a shaft body insertion hole for the shaft body. The bolt insertion hole is a lateral oblong hole extending in a direction inclined, with respect to the horizontal direction, toward a direction orthogonal to a load acting direction in the lateral rollover.

According to one embodiment, a controller for a storage apparatus is disclosed having interfaces connectable to a host system, a first storage apparatus and a second storage apparatus. A data in the first storage apparatus and a data in the second storage apparatus are duplicates. A status table stores the operating state regarding the first storage apparatus and the second storage apparatus, wherein the operating state indicates among writing, reading, or standing by. A monitor monitors the interfaces and set up the operating state into the status table. A buffer memory buffers the data for writing in the first storage apparatus and the second storage apparatus. A command response unit receives the data for writing and write-in request from a host system, and directs the writing of the data to the first storage apparatus and the second storage apparatus while making the buffer memory buffer the received data.

A controller is connectable to a host system and a plurality of storage devices. A monitor unit monitors operating status of a plurality of storage devices and sets the operating status of the storage devices in a status table. Upon receiving a write command from the host system, a command responding unit receives write data sent from the host system within a certain period of time after the write command, holds the write data received in a buffer memory, instructs a timer to start counting, sets a write destination for data in the status table, outputs a control signal that gives an instruction to write data to the storage device of the write destination, and returns a write completion response corresponding to the write command to the host system when receiving the deadline notification from the timer.
