Travel Circuits 1. High-speed Travel Circuit With high speed travel, high speeds can be achieved by setting the two-level inclinatory angle of the travel motor to the smaller angle side. The circuit has a travel motor that automatically switches over to lower speed by utilizing load pressure on the travel motor when traveling at high speed.

Discharged oil from the hydraulic pump A1 enters the port P1 of control valve while discharged oil from the hydraulic pump A2 enters the port P2 of control valve. Each flow goes into the travel motor by switching between the right and left travel spools. By these flows, the machine travels forward and backward.

By operating the travel mode switch, electric signals are sent to the controller, and from the controller, electric signals are sent to the solenoid valve for 2-speed (high speed) travel in the 6-way solenoid valve.

By the switchover of the solenoid valve, the original pilot pressure (3.9 MPa) from port C1 on the 6-way solenoid valve enters port P of right and left travel motors via the rotating joint to set the inclinatory angle of the travel motor to the smaller angle side, which enables high speeds.

2. Low Speed Travel Circuit The two-level inclinatory angle in the travel motor is set to the larger angle side. When the travel status is set to high speed and the key switch is turned off and turned on again, the speed setting will always return to low speed.

Discharged oil from the hydraulic pump A1 enters the port P1 of control valve while discharged oil from the hydraulic pump A2 enters the port P2 of control valve. Each flow goes into the travel motor by switching between the right and left travel spools. By these flows, the machine travels forward and backward.

The solenoid valve for high speed travel is turned off and the oil in port P of the travel motor enters the tank line and establishes a connection. As a result, the inclinatory angle of the travel motor is set to the larger angle side.

3. Straight Travel Circuit As an example, we describe the operation where travel and boom up are operated at the same time.

The pilot oil pressure enters from port PP of the control valve and communicates with the tank side via passages of travel spool and spools for attachments (boom, arm, bucket and swing). When travel and boom-up operations are performed simultaneously, all circuits, which have been communicating with the tank, will be shut off by spools. This makes pilot pressure oil entered from the port PP to lose where to flow and original pressure (3.9 MPa) switches over the straight travel selector valve. The pressure works to the pilot chamber in straight travel valve allowing the valve to be switched over.

As the result of the switchover of the straight travel valve, the pressurized oil in the control valve P1 drives the right and left travel motors and the pressurized oil in the control valve P2 drives the attachments. The right and left pressures become equal because one pump drives both the right and left motors. This realizes straight travel. Additionally, extra hydraulic oil from P2 is supplied via the check with travel confluence restriction to the travel side, and speed reduction is minimized. The same theory applies and the circuits operate the same way when upper actuators other than boom and travel are operated at the same time.

Swing Circuits 1. Swing Parking Circuit (Lever in Neutral / Swing Locked) When the engine is started and the swing lever is in neutral, the swing brake solenoid valve becomes turned on (24 V input) and the swing parking brake is activated.

When the swing lock switch is on, even if the swing pressure switch or attachment pressure switch is turned on, the swing lock switch overrides and the parking brake remains unreleased. Since pressure oil out of the port C5 of 6-way solenoid valve works on both sides of the swing spool while the swing is being locked, the spool in the control valve will not be switched over even if the swing control lever is engaged.

2. Swing Parking Circuit (Brake Released) When the swing pressure switch is turned on by operating the lever, output to the swing brake solenoid valve from the controller is turned off and the swing parking brake is released by pilot pressure. Also, in order to prevent brake dragging caused by swing lateral force that is generated when digging attachments are moved with the swing lever being in neutral, a mechanism which senses main pressure and releases the parking brake is introduced. Signals from the pressure sensor on port pr1 or port pr2 of the control valve enter the controller. When either pressure reaches 15 MPa, the output to swing brake solenoid valve from the controller is turned off. This releases the swing parking brake.

When the pressure switch for attachments is kept off for more than 5 seconds, the swing pressure switch will be turned off. Then 5 seconds after the pressure of the control valve pr1 or pr2 becomes 15 MPa or less, the solenoid valve turns on and the swing parking brake starts operating. When the pressure on G4 or G5 becomes 15 MPa or more, the swing brake is released. However, if the attachment switch was kept off for more than 5 seconds, the swing parking brake works.

2. Arm-In Load Holding When the arm is in neutral, oil on the arm cylinder rod side is sealed by the load holding valve check. This mechanism reduces internal leakage from the main spool.

When the arm-in is operated, the pilot pressure enters port pa5 of the control valve and moves arm (1) spool to the arm-in side. Also, the pilot pressure separated from port pa5 enters port pc1 and moves the load holding valve spool to the right. Through this mechanism, the oil in the spring chamber of the load holding valve check is connected to the tank line passing the load holding valve spool. As a result, the pressure on the spring chamber decreases and the load holding valve check is released. The hydraulic oil in the rod of the arm cylinder is returned to the tank line, the arm cylinder extends and the arm moves in.

3. Arm-In Circuit For arm-in operation, pilot pressure is supplied to port pa5 and pa9 of the control valve and the arm spool moves to the arm-in side.

At the same time, the arm load holding valve is released by the pilot pressure, and the discharged oil on the cylinder rod side is restricted by the forced regenerative release valve. This forces the returned oil to be regenerated into the cylinder bottom side via the check within arm (1) spool, securing the arm speeds required for floor digging work. When the load pressure rises on the cylinder bottom side, the forced regenerative release valve switches over to the large diameter restriction side. As a result, the orifice for return becomes large and returned oil on the rod side stops recycling.

2. Boom-Up Circuit (Combined) When floor digging operation is performed, the boom-up pilot pressure, which is supplied to port pc5, releases the restriction on flow to the arm by moving the swing priority variable restriction to the left. This makes the arm move smoothly.

3. Boom-Down Load Holding When the boom is in neutral, oil on the boom cylinder bottom side is sealed by the load holding valve check. This mechanism reduces internal leakage from the main spool. For boom-down operation, the pilot pressure enters port pb7 of the control valve and moves the spool of the control valve to the boom-down side. Also, the pilot pressure enters port pc2 and moves the load holding valve spool to the left. Through this mechanism, the oil in the spring chamber of the load holding valve check passes the load holding valve spool creating a connection to the tank. Consequently, the pressure on the spring chamber decreases and the load holding valve check is released. The hydraulic oil at the bottom side of the boom cylinder is returned to the tank line, the rod of the boom cylinder shrinks, and the boom is lowered.

4. Boom-Down Circuit For boom-down operation, pilot pressure is supplied at port pb7 of the control valve, and the boom spool moves to the boom-down side. At the same time, the pilot pressure opens the boom load holding valve and partially regenerates the discharged oil from the bottom side of boom cylinder at the rod side via the check in the spool. (The lower the load pressure of the cylinder rod side, the more the regenerated volume will be.)

When the boom is moved down as quickly as possible and the spool is at full stroke, negative pressure is generated by bleed-off oil passage in the center bypass. High pressure generation is coutrolled, and vibration of the body is reduced. Since the lack of oil is to be supplemented in the regenerative circuit, engine output can be effectively used.

Backup Circuits 1. Combined Circuit (Breaker Circuit) Through remote control operation, the pilot pressure that is supplied to port pb4 of the control valve switches the backup spool. This allows the discharged oil from the hydraulic pump A1 to flow into the breaker.

The pilot pressure operates the pressure switch at the same time. When the change-over switch in the cab is turned to breaker mode, the controller directs the engine controller by signal from pressure switch so that the speed can match the previously set engine speed.

Return oil from the breaker passes by way of 3-direction valve, and oil exceeding the set pressure flows from the stop valve via the relief valve to return to the hydraulic oil tank.

2. Combined Circuit (High Speed Confluence Circuit) Through remote control operation, the pilot pressure that is supplied to port pa4 (or pb4) of the control valve switches the backup spool. This allows the discharged oil from the hydraulic pump A1 to flow into the end attachment.

Turning the change-over switch in the cab to crusher (2) energizes the solenoid valve so that the valve is switched over.

Pilot pressure divided via remote control valve is fed in the port pa10 by way of solenoid valve.

This changes over the spool to block the center-bypass circuit.

The blocked discharge oil of hydraulic pump A2 flows by way of merging passage to be combined together with the discharged oil out of hydaulic pump A1 at upper flow course of the spare spool.
