摘要： Measurement and a display of a load of digging a blasted ground which can contribute to accurate blasting. The operating direction of the backet of an excavator is detected by pressure switches (15 and 16), and the pressure PB of the bottom chamber 6SB of a backet cyclinder is detected by a pressure sensor (17). A processor (23) calculates the excavation position in accordance with the signals from a boom angle sensor (18), an arm angel sensor (19), a GPS (20) and a magnetic azimuth sensor (21), integrates the pressure PB in the ON-period of the pressure switch (15) and transmits the excavation position and the integrated pressure to a computer (30) through wireless transmitters/receivers (24 and 31). The computer (30) displays the map of the blast area and the blasting positions and superposes the transmitted excavation position on the map with a mark (x) and the transmitted integrated pressure with a figure. It is judged whether the blasting is proper or not by referring to the integrated pressure, and the judgement is utilized for the next blasting.

摘要： Formed on an end portion of an upper cover (8) on a side of a work front (5) is a curved portion (45), by which interference with the work front (5) is avoided. The curved portion (45) comprises a concave surface (45A) having a central axis on an axis (m) of a vertical pin of a swing post (4), a first stepped portion (45B) provided on a lower end of the concave surface (45A) and defining a substantially uniform gap between it and a path, which a rear projection (4A) of the swing post (4) describes when the work front (5) swings, and a second stepped portion (45C) provided on a vertically middle portion of the concave surface (45A) and provided with a substantially horizontal surface (45C1), by which scaffolding is ensured. The concave surface (45A) is shaped to extend along and define a gap between it and a path, which a rear surface of a boom (16) describes when the work front (5) swings in its minimum swinging posture. The first stepped portion (45B) comprises a substantially vertical curved surface (45B1) formed contiguous to the lower end of the concave surface (45A) and defining a substantially uniform gap between it and a path, which the rear projection (4A) of the swing post (4) describes when the work front (5) swings, and a substantially horizontal surface (45B2) formed contiguous to the curved surface (45B1) on the side of the work front (5) and defining a substantially uniform gap between it and a path, which a lower end of the rear projection (4A) of the swing post (4) describes when the work front (5) swings.

摘要： An excavator comprising a swing type front working mechanism (7) with a boom (8) that includes a lower boom member (8L) connected at its foot pivotably via a pin (18) to brackets (12a) constituting a mount for a swing post (12). A cross-link (40) is connected pivotably via pins (41, 42) to the portion of the boom (8) which is between the brackets (12a) and an upper boom member (8U). The cross-link (40) is provided on the right side of the boom (8), not beside a cabin (6). Consequently, the cross-link (40) is put in a cantilever-like condition, and a partial load occurs on the boom (8), so that stress becomes higher on the side portion of the boom (8) on which the cross-link (40) is provided to cause lateral bending stress to be exerted on the lower boom member (8L). In order to lessen the lateral bending stress, a lateral bending load lessening means is formed which is adapted to shift the position of a boom driving hydraulic cylinder (43) from a position on an axis (A1) of the lower boom (8L) to a position on the opposite side of the cabin (6).

摘要： When a mode signal Sm of a mode switch (13) is ON, an arithmetic unit (12a) of a controller (12) executes learning control in which a driving current (I) corresponding to a predetermined target pump rotation theta 0 is supplied to a proportional solenoid valve (3) to determine the difference between the target pump rotation theta 0 and actual pump rotation theta and the difference is stored as a corrective value DELTA theta 0 in an EEPROM of a memory unit (12b). When the mode signal Sm of the mode switch (13) is OFF, the arithmetic unit executes normal control in which the corrective value DELTA theta 0 stored in the memory unit (12b) is added to the target pump rotation theta 0 and a driving current (I) corresponding to this corrected target pump rotation theta 0 is supplied to the proportional solenoid valve (3). Therefore, even when any variance exists in the input/output characteristics of a regulator as displacement control means (control objet) of a hydraulic pump and the proportional solenoid valve, variance of actual pump rotation as the output of the control object can be reduced.

摘要： In a hydraulic controller, in order to easily provide a hydraulic back-up in the event of a failure of an electric system while maintaining a benefit of electrical control using a control unit (13) when controlling a displacement of a hydraulic pump (1) in accordance with a property of a hydraulic driving system, a pump regulator (16) is constructed such that the tilt theta of a swash plate (1a) increases as the pressure of a second oil pressure signal P.c decreases, the pump regulator is characterized in that a negative control pressure can be used instead of the second oil pressure signal, and the properties of a fixed throttle (10) and the pump regulator spring (18d) are set such that the pump regulator can be operated within an operation range of the negative control pressure. In a controlling unit (13), a negative control pressure Pc1 corrected in a block (102) is made to be a target value of the second oil pressure signal, a second electric signal E corresponding to the target value is obtained, and the operational range of a second oil pressure signal generated by a solenoid proportional valve (15) is made substantially equal to the negative control pressure.
