An actuator control device performs a reception process in which designations of a minimum operation amount and maximum operation amount of an operation unit for driving an actuator, and a maximum driving speed which is the actuator driving speed corresponding to the maximum operation amount are received. It also performs a determination process in which a function representing a characteristic line that links a first point, which corresponds to the minimum operation amount and the driving speed of 0, and a second point, which corresponds to the maximum operation amount and the maximum driving speed, is stored in a storage unit as a drive control characteristic and a drive control process in which, in response to operation of the operation unit, the actuator is driven at a driving speed corresponding to the operation amount specified by the drive control characteristic stored in the storage unit.

The present invention is configured so that it is possible to select any one of a first mode in which a first adjustment valve 13 and a second adjustment valve 20 operate solely on the basis of manipulation of a main manipulation tool (turning lever 8i), a second mode in which the first adjustment valve 13 operates solely on the basis of manipulation of the main manipulation tool (8i) and the second adjustment valve 20 operates solely on the basis of manipulation of a secondary manipulation tool (brake pedal 8j), and a third mode in which the first adjustment valve 13 operates solely on the basis of manipulation of the main manipulation tool (8i) and the second adjustment valve 20 operates on the basis of manipulation of the secondary manipulation tool (8j) while operating on the basis of manipulation of the main manipulation tool (8i).

A crane control for a crane includes at least one operating unit operable by an operator for controlling working functions of the crane. Control signals can be input to actuators of the crane by the operating unit, and a mounting arrangement is provided for mounting the operating unit in a driving cab of the vehicle and a support arrangement connects the operating unit to the mounting arrangement. The support arrangement for the operating unit is supported limitedly moveably between at least two positions, a first position of which is in the form of a working position in which the operating unit is between a steering arrangement of the vehicle and a driving seat, and a second position of which is in the form of a storage position in which the operating unit is moved away from the steering arrangement of the vehicle.

A working machines capable of securing safety while enabling remote operation is a working machine configured to be capable of communicating with a remote operation device (40), and includes a communication unit (70a) that receives a manipulate signal from the remote operation device (40), a control unit (70) that controls actuators (51 to 59) mounted in the working machine according to manipulate signals from main operation devices disposed in a cab of the working machine or the remote operation device (40). In a case where a state of the working machine does not fulfill a predetermined condition, the control unit (70) does not allow the remote operation of at least one of the actuators (51 to 59) by the remote operation device (40).

A one-handed joystick for cranes allows an operator to make all necessary motions with a single hand and arm for manipulating various components of a crane. The one-handed joystick includes a rotatable cylinder bar, a rotatable ring, an industrial joystick base, a rocker switch and at least two push button switches. Motions of the rotatable cylinder bar, the rotatable ring, the industrial base and the rocker switch are used to raise and lower the auxiliary hoist; raise and lower the telescopic boom for luffing a hoist; raise and lower the main hoist; slew the boom base in a clockwise or counterclockwise direction; and extend or retract the telescoping boom. The speed of main and auxiliary hosts may be changed with the two push button switches. A Deadman's switch may be installed on a back side of the rotatable cylinder bar.
