Abstract (en)

[origin: EP0480037A1] An operating device for the traveling and working machines of the excavator, which is provided whith a separation-mode release switch (18) capable of temporarily changing over a separation mode providing a low working speed of an actuator to a standard mode allowing a high working speed when the working speed of the actuators (6, 7, 8, 9, 10, and 11) is desired to be increased during working performed in the low-working-speed separation mode in which the operability of the actuators (6, 7, 8, 9, 10, and 11) is an important factor.
