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 folding assembly for an actuation lever is disclosed. The folding assembly includes a first shaft and a second shaft pivotally coupled to the first shaft. The second shaft includes a first engagement structure and a second engagement structure spaced apart from the first engagement structure. The folding assembly further includes a sleeve slidably disposed around the first shaft and the second shaft. The sleeve comprises a mating structure adapted to engage with the first engagement structure or the second engagement structure. The sleeve is adapted to cover a portion of the first shaft and a first portion of the second shaft, when the mating structure is engaged with the second engagement structure. Further, the sleeve is adapted to cover a second portion of the second shaft such that the sleeve releases the first shaft, when the mating structure is engaged with the first engagement structure.

A mechanical linkage for a power machine includes first and second horizontal shafts extending sideways along respective first and second axes. First and second links are operably coupled to the respective first and second horizontal shafts. The links convert actuation of operator input devices of the power machine into rotation of the horizontal shafts about their axes. First and second valve actuators convert rotation of the respective first and second horizontal shafts into actuation of respective first and second spools in a hydraulic valve of the power machine.

The present invention relates to the field of engineering mechanics and more particularly, relates to an engineering work vehicle, and most particularly, relates to a vehicle with a rotary control box and aerial working platform. The vehicle with a rotary control box includes: a vehicle frame, a driving system disposed on the vehicle frame, and a control box; the control box is disposed at a lateral side of the vehicle frame in a rotary manner; and the control box is electrically connected with the driving system. embodiments of current invention makes it possible to manipulate with ease the aerial work platform to perform corresponding motions by an operator standing on the ground and, this kind of manipulation is quick and accurate. In addition, more convenience and human-friendliness is brought. At the same time, life time of relevant components of the aerial work platform is extended, and maintenance and repair cost is further reduced.

[Problem] To provide an actuator control device with which desired drive control characteristics can be obtained by means of a simple operation.

[Solution] This device performs: a reception process (S12) 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; a determination process (S13, 14) 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.

A portable transmitting/receiving device (2), in particular in the form a remote control device for lifting and industrial devices, has a housing (4) which has a receiving portion (6) for accommodating an electronic controller and for mounting at least one operating element (such as a joystick, switch, regulator, or touchscreen with virtual operating elements) (14). Additionally, the housing (4) extends in the vertical direction (V) from a lower-face base contour (18) to an upper-face terminating contour (20) and is perpendicularly delimited by a lateral contour (22). At least a substantial part of the housing (4) is made of a molded housing part (16) made of an elastomer, said molded housing part forming at least the upper-face terminating contour (20) and the lateral contour (22). The molded housing part (16) forms a basin which delimits the receiving area and which has a circumferential wall (24) that is completely made of an elastomer and which has a closable opening.
