摘要:
There is provided a control system for a hydraulic construction machine that helps to attain predetermined finish accuracy even if the excavating load increases during a horizontally leveling operation or a slope face forming operation. The control system for the hydraulic construction machine includes: a hydraulic actuator; a work device driven by the hydraulic actuator; a hydraulic pump supplying a hydraulic fluid to the hydraulic actuator; a pump flow rate control section controlling the delivery flow rate of the hydraulic pump; a pump horsepower control section controlling the horsepower of the hydraulic pump; and a target surface distance acquiring section measuring or computing a target surface distance that is the distance between a construction target surface on which the work device works and the work device. The pump flow rate control section is configured to perform control such that as the target surface distance decreases, the delivery flow rate decreases, and the pump horsepower control section is configured to perform control such that as the target surface distance decreases, the horsepower of the hydraulic pump increases.

In an operating device for a double arm type hydraulic excavator 1 comprising a left operating device 50 provided on the left side of a cab seat 49 and a right operating device 51 provided on the right side of the cab seat 49, the left operating device 50 includes a left control lever 54 and a left control switch 56 provided on the left control lever 54, while the right operating device 51 includes a right control lever 55 and a right control switch 57 provided on the right control lever 55. The shortest distance between the left control lever 54 and the right control lever 55 is greater than the width of the cab seat 49. The operation of a right front work implement B is performed by using the left control lever 54 and the right control lever 55. The operation of a left front work implement A is performed by using the left control switch 56 and the right control switch 57. With this configuration, the operation of the double arm type hydraulic excavator can be performed in a manner similar to that in conventional technology and the operator can sit down on the cab seat without a hitch while avoiding breakage caused by a contact with the control lever.

Disclosed embodiments include power machines that provide an electronic tag along mode of operation. A control system is coupled to and selectively provides power to the left and right side tractive elements from the power source. First and second user input devices each provide an actuation signal indicative of manipulation between a neutral state and a forward state. An electronic tag-along input device provides a tag-along activation signal. When each of the first and second user input devices are in the forward state and the electronic tag-along input device provides a tag-along activation signal, a controller maintains power to the left and right side tractive elements when one of the first and second user input devices is in the forward state and the other of the first and second user input devices is the forward or neutral state.
