摘要： A motor is driven with variable frequency AC power converted from DC power, and an AC output power from the motor is converted to DC. In the conversion, an electromotive force regenerated by the motor is consumed by a plurality of resistors. When the consumption of the electromotive force is impeded in any of systems including any of the plurality of resistors, the electromotive force is consumed by the systems including the remaining resistors. Even if a system including any of the plurality of resistors fails, the electromotive force can by consumed by the other systems including the remaining resistors, thus providing a reliable rheostatic brake.

摘要： This invention relates to a measuring and display system for loads applied upon digging blasted earth, which can contribute to accurate blasting. An operating direction of a bucket of an excavator is detected by pressure switches 15,16, while a pressure P.sub.B in a bottom compartment 6S.sub.B of a bucket cylinder is detected by a pressure sensor 17. A processor 23 computes a digging position based on signals from a boom angle sensor 18, an arm angle sensor 19, GPS 20 and a magnetic direction sensor 21, integrates pressures P.sub.B during an ON period of the pressure switch 15, and transmits the thus-integrated pressure together with the digging position to a computer 30. The computer 30 displays a map of a lot under blasting and blasting positions on a display, and on the map, also displays the thus-transmitted digging position by a mark X and the integrated pressure by a numeral. With reference to this integrated pressure, a determination is made as to whether the blasting was proper or improper. The results of this determination are used for the next blasting.

摘要： A system for the estimation of residual service time of a work vehicle includes an arithmetic and logic unit which is inputted with an engine speed and a speed difference from a controller for an engine, with a signal, which indicates whether or not at least one of several control levers has been operated, from a lever position detector, and also with a residual fuel quantity in a fuel tank from a converting device. The residual fuel quantity is determined at intervals of about 1 hour at the arithmetic and logic unit. Upon an elapse of each short period of time, a quantity of fuel consumed during said short time, said quantity being obtained based on a difference in engine speed, is subtracted from the residual fuel quantity, whereby a calculated residual fuel quantity is obtained. A quantity of fuel consumed from a preceding residual fuel quantity measurement period to a current residual fuel quantity measurement period is divided by the calculated residual fuel quantity to obtain a value. The residual fuel quantity is then divided by this value to compute a residual service time, which is then displayed on a display.

摘要： A hydraulic control valve is controlled and changed over by a hydraulic pressure output from a remote control valve. A change-over valve is provided between an output port of the remote control valve and a pilot port of the hydraulic control valve. The change-over valve connects the output port of the remote control valve to the pilot port of the hydraulic control valve when the remote control valve is operated, and it connects the pilot port of the hydraulic control valve to a tank when the remote control valve is set to the neutral position. The change-over valve comprises a hydraulic change-over valve capable of establishing the above states of connection by the hydraulic pressure output from the remote control valve, or an electromagnetic change-over valve capable of establishing the above states of connection by electrically detecting the operation of the remote control valve.

摘要： A drive system of an electrically driven dump truck is capable of achieving an operational feeling in which the operation amount of the accelerator pedal is well balanced with the output horsepower of the electric motors, particularly at the time of slow traveling. To achieve this, the target motor output horsepower Pm0 corresponding to the operation amount of an accelerator pedal 1 is calculated. The target motor torque Tr1R, Tr1L is calculated on the basis of the target motor output horsepower Pm0 and the rotational speed ωR, ωL of electric motors 12R, 12L respectively. The acceleration torque limit values of the electric motors 12R, 12L corresponding to the operation amount of the accelerator pedal 1 are calculated, respectively. Then, smaller values are selected, as motor torque instruction values TrR, TrL, between the acceleration torque limit value and the target motor torque Tr1R, Tr1L to control inverters 73R, 73L, respectively.

摘要： An upper cross beam 10 for supporting a rear side of a cab 19 from below is formed as a separate member from a base frame 7. This upper cross beam 10 is separably mounted on left and right column portions 7E of the base frame 7 by using bolts 12. Namely, when an engine 27 is mounted to the base frame 7, the upper cross beam 10 is separated in advance from the base frame 7. Consequently, at the time of the operation of carrying in the engine 27, it merely suffices to vertically hoist or lower the engine 27 by use of a crane. It is thereby possible to carry in the engine 27 between the column portions 7E of the base frame 7 without being hampered by the upper cross beam 10.
