摘要： In order to improve the durability of a tooth edge of an excavator and thereby an excavation efficiency thereof as well, a penetration force control unit (70) controls a hydraulic winch HWD so that a detected penetration force attains a set level, whereby the speed of the excavator (10) is controlled. A descending speed control unit (50) is adapted to control the hydraulic winch HWD so that a detected descending speed attains a set level, whereby the speed of the excavator (10) is controlled. When a detected level of the descending speed exceeds a predetermined level during a control operation of the penetration force control unit (70), a selection unit (80) shifts the control operation to that by the descending speed control unit (50). The descending speed control unit (50) is adapted to control the descending speed by a proportional integration control operation, while the penetration force control unit (70) is adapted to control the penetration force by a proportional differentiation control operation.

摘要： In an excavation region setting apparatus for controlling the region limited excavation by a construction machine, which is adapted to calculate a target speed vector Vc for use in controlling a front unit (1A), on the basis of a vehicle body (1B), restrict when the front unit approaches a boundary of a preset excavation region the moving speed thereof in the direction approaching the same boundary, by correcting the target speed vector, and move the front unit along the mentioned boundary, an outer reference 80 is set first in the horizontal direction in a position outside a hydraulic shovel body, and a depth hr between the outer reference and the boundary of the excavation region is then set by using a setter (7), for the purpose of setting the excavation region. The front unit (1A) is then moved, and, when the position of a front reference 70 agrees with that of the outer reference, an outer reference setting switch (71) is pressed. Consequently, a control unit (9) computes a height hf between a vehicle body reference point O and the outer reference, and then a height hs of a boundary surface of the excavation region with respect to the vehicle body reference point O on the basis of this depth hr by using the height hf as a correction value, and set the excavation region based on the vehicle body (1B), on the basis of which the target speed vector Vc is calculated. This enables the setting of an excavation region suitable for an excavation control operation in which computation is carried out on the basis of the vehicle reference to be done, and a highly reliable control operation to be carried out.

摘要： When a solenoid proportional valve (91A) of a direction control valve (8A) is left open due to failure and an operator makes a reverse lever operation for operating an operation lever (4A) in an x2 direction, a low level signal is outputted from an operation position sensor (30A2) and a high level signal is outputted from operation position sensors (30A1, 30B1, 30B2). Since the output of an AND circuit (6b2) becomes a low level signal and the output of an AND circuit (6b1) becomes a high level signal, a change-over signal is outputted from an amplification circuit (6h) to a solenoid change-over valve (121), so that the solenoid change-over valve (121) is switched to a right side position in the figure to allow a pilot line (51) to keep communicating with a tank (97). The change-over signal is not outputted from the amplification circuit (6h) to a solenoid change-over valve (122), and the solenoid change-over valve (122) is kept at a left side position in the figure. Accordingly, the pilot line (52) keeps communicating with a pilot pump (96). At this time, a driving signal from a metering calculation portion (6a) is inputted to a solenoid proportional valve (92A) of a direction control valve and the solenoid proportional valve (92A) is excited, so that a secondary pilot pressure is given from the solenoid proportional valve (92A) to a pilot operation portion (22A) of the direction control valve (8A). Because a primary pilot pressure to the solenoid proportional valve (91A) is reduced by the solenoid change-over valve (121) to the tank pressure, the direction control valve (8A), that has existed at the left side position in the figure, is switched to the left and can be easily returned to a neutral position.
摘要翻译：当方向控制阀（8A）的电磁比例阀（91A）由于故障而打开，并且操作者进行用于在x2方向上操作操作杆（4A）的反转杆操作时，从从操作位置传感器（30A1,30B1,30B2）输出操作位置传感器（30A2）和高电平信号。由于AND电路（6b2）的输出变为低电平信号，AND电路（6b1）的输出变为高电平信号，所以转换信号从放大电路（6h）输出到电磁变换信号（121），使得电磁转换阀（121）切换到图中的右侧位置，以允许先导管线（51）与罐（97）保持连通。转换信号不从放大电路（6h）输出到电磁转换阀（122），电磁转换阀（122）保持在图中的左侧位置。因此，先导管路52与导向泵（96）保持连通。此时，来自计量计算部（6a）的驱动信号被输入到方向控制阀的电磁比例阀（92A），电磁比例阀（92A）被激励，从而从电磁比例阀（92A）连接到方向控制阀（8A）的先导操作部分（22A）。由于电磁比例阀（91A）的初级先导压力被电磁转换阀（121）减小到油箱压力，所以在图中左侧位置存在的方向控制阀（8A）被切换到左侧并且可以容易地返回到中立位置。
