摘要： A fluid-pressure transmitting apparatus that is capable of securing the operationality of a working machine and braking and preventing against engine stall. The apparatus can switch between a working-machine operating device and a traveling operating device. When a second operating unit is operated during operation of a first operating unit, the pilot pressurized oil outputted from each operating means through first and second pilot-pressure admission passages is admitted to a low-pressure selecting valve. At this time, the pilot pressurized oil is automatically selected through the low-pressure selecting valve to control the delivery capacity of the traveling pump and braking and preventing engine stall and realizing travel at low speed.

摘要： A cooling-fan control device for a vehicle that increases the cooling capacity of a cooling oil that cools a brake rapidly and inhibits a brake damage in a case where the brake is applied during traveling or, in addition to the above-described problem-to-be-resolved, suppresses engine horsepower consumption and avoids consumption increase, while increasing the cooling capacity of the brake cooling oil. The rotation speed of the cooling fan is controlled to obtain the higher target rotation speed of a first target rotation speed corresponding to a detected cooling oil temperature and a second target rotation speed corresponding to a detected brake operation amount. The present invention is applicable to a vehicle in which an engine power is distributed to a travel power train and a hydraulic pump, drive wheels are operated via the travel power train, and the cooling fan is actuated via the hydraulic pump.
