摘要： PURPOSE: To enhance the safety, by providing a stability-discriminating mechanism during operation, which discriminates the dynamic stability of a traveling body on the basis of detected results from detection mechanisms of situations of the working area and the traveling body and outputs the result. CONSTITUTION: A controller operates a new stabilizing value on the basis of detected signals from a sensor 12 for the inclination of a traveling body, a sensor 13 for the direction of the upper gyratory body, a sensor 14 for the inclined angle of the boom, a sensor of the boom pressure, a sensor 17 for the inclined angle of the arm, a sensor for the arm pressure, and a sensor for the length of a telescopic cylinder. When the stable value of the body is discriminated to be within a preset safe range by the controller, a control signal is output to open the pilot oil pass to a control valve for alarm, to actuate it. When the stable value of the body is discriminated not to be within a preset safe range by the controller, an actuating signal is output to the alarm and a control signal is output to close the pilot oil pass to the control valve for alarm, to stop the actuation.

摘要： PURPOSE:To provide a booster device capable of automatically obtaining boosted oil pressure when necessary, without resetting the rated pressure of a hydraulic system. CONSTITUTION:An operating valve 12 connected to a hydraulic pump 13 directional-controls pump-discharged pressure oil to control an opening and closing cylinder 4 for opening and closing a jaw of a breaker. A pilot type check valve 8 is interposed between expansion side oil passages 271, 272 between the operating valve 12 and the opening and closing cylinder 4. The checking action of the check valve 8 is released by pilot pressure guided from a contraction side oil passage 28 on the opposite side through a pilot oil passage 9. A sequence valve 7 is provided on an oil passage 26 branched from the expansion side oil passage 271 on the operating valve 12 side from the check valve 8. An electromagnetic change-over valve 6 is provided on a supply oil passage 29 supplied with pressure oil through the sequence valve 7. A double acting boosting cylinder 5 is connected to output oil passages 241, 242 of the electromagnetic change-over valve 6. The boosting cylinder 5 outputs boosted pressure oil to the expansion side oil passage 272 on the opening and closing cylinder 4 side from the check valve 8.

摘要： PURPOSE:To promote the replacement work by disengageably locking a pair of pins provided on a working attachment, to a stationary hook and a movable hook which are provided in a working front part. CONSTITUTION:A pin 7' on a working attachment such as a bucket, is inserted into a hook part of a stationary hook 10. Then, a cylinder 12 is retracted so as to rotate a cam 11 in the direction of the arrow H in order to retain the coupling part between links 14, 15 in the direction of the arrow I. At this time, a movable hook 11 is rotated in the direction of the arrow J by means of the link 15 since the hook 10 side of the link 14 is supported by the pin 7'. After a pin 8' on the working attachment enters a hook part of the hook 11, the hook 11 is pressed in the direction of the arrow J by means of a toggle mechanism for the links 14, 15 so that the pin 8' is surely held. Further, in the case of the removal, the cylinder 12 is extended, the pin 8' is released from the hook 11 under the action of a return spring 17. With this arrangement, the replacement can be surely and rapidly made by only one operator.

摘要： PURPOSE:To accomplish stable communication and remote control by switching a remote control means between wireless system and wire system according to the status of an electric wave. CONSTITUTION:During the remote control by a normal electric wave, a cable 9 is not connected. In a cable connection discriminator 10a of 2 transmitter 1b side, a cable connection 'NO' decision signal 11a is sent out to a signal processor 2b, and a transmit signal (TX) from the signal processor 2b is connected to a high frequency amplifying portion 3b. During remote control by a wire system, the cable 9 is connected. A 'YES' decision signal 11a is sent out to the signal processor 2b and a transmit signal TX is connected to an input/output buffer 12a. A power supply receiving circuit 16 receives a power supply sent from a receiver 15b through the transmit/receive cable 9. In the receiver 15b, a power supply is supplied from a power supply circuit 17 through the transmit/receive cable 9 to the transmitter 1b side. Thus, stable communication can be ensured, and a machine can be remote-controlled smoothly.

摘要： PROBLEM TO BE SOLVED: To provide an interference prevention device of a working machine capable of surely preventing a cab liftably installed on a machine body from being interfered with the attachment of the working machine.
SOLUTION: A controller 64 sets an interference prevention area A on a coordinate so as to cover the all movement area of the cab 13 formed liftably, and calculates the coordinate of a part B to be monitored from information on boom angle sensor 62, a stick angle sensor 63, and the maximum diameter of an attachment 28. Solenoid proportional valves 66 as pilot pressure stop valves are installed in a pilot line 48bu for boom up and a pilot line 48si for stick-in. The solenoid proportional valve 66 has a function to eliminate a pilot pressure signal for boom raising and a pilot pressure signal for stick-in to a control valve 42 by a pilot pressure stop signal output from the controller 64 according to a determination that the part B to be monitored reaches the interference prevention area A.
