WORKING MACHINE
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).
Remote-controlled crane
The present disclosure concerns a crane, in particular a tower crane, telescopic boom crane, harbor crane and the like, with a load hook that can be raised or lowered via movable crane elements, and moved within a crane working area by operating drive units associated with the crane elements. The crane is provided with a control unit with input means to control the drive units. According to the present disclosure, the crane uses a mobile portable target signal transmitter that can be variably positioned in the crane working area, and positioning means for automatically determining the current position of the target signal transmitter relative to the load hook and/or a crane element, and target control means for automatically controlling the drive units in response to a signal from the positioning means, such that the load hook is automatically moved to the mobile target signal transmitter.
Crane and crane control method based on current and target boom tip and load positions
A crane is provided. The crane includes an acceleration sensor that detects the acceleration of a load, wherein a target velocity signal is converted into target location coordinates of the load, current location coordinates of a boom are calculated from a slewing angle, a luffing angle, and an expansion/contraction length, the spring constant of a wire rope is calculated from the previously calculated location of the load from a unit time earlier, the current location coordinates of the boom, and the current accelerations of the load as detected by the acceleration sensor, target location coordinates of the boom are calculated from the accelerations, the spring constant, and the target location coordinates of the load, and an actuator operation signal is generated.
Remote operation terminal and mobile crane provided with remote operation terminal
A remote operation terminal of a crane provided with a GNSS receiver for calculating the current position of the tip of a boom: acquires attitude information of the crane and the current position of the tip of the boom from a control device of the crane; generates a three-dimensional image of the crane at the current time and planimetric features on the basis of the information acquired from the control device and three-dimensional information acquired by a three-dimensional information acquisition unit; displays, on a display device, the generated three-dimensional image at the position of and in the direction of a viewpoint input to a viewpoint changing operation tool; and generates a control signal for the crane so that the tip of the boom of the three-dimensional image moves in a moving direction input to a suspended load moving operation tool in the three-dimensional image of the crane displayed on the display device.
SYSTEM FOR SAFE AUTOMATED LASHING OF CONTAINER CRANE FOR PROTECTION AGAINST TYPHOONS
An automated system mainly includes a stowage module (100), a tiedown module (200), a socket anchor module (300), and an encoder module (400) and has an improved structure for a stowage pin and the tiedown module to be remotely controlled by unmanned automation to significantly decrease the crane securing time, thereby promptly dealing with emergency situations with maximum terminal operation efficiency and minimum manpower.
Direction Based Remote Control of a Material Handling System
A radio controller includes a sensor to detect orientation of the transmitter. The orientation is used in combination with a command from the joystick to control operation of the bridge and/or trolley of a material handling system. In a first operating mode, rotational orientation is divided into two intervals. When the transmitter is facing a first direction, pressing forward causes the commanded axis to travel forward. When the transmitter is facing opposite the first direction, pressing forward causes the commanded axis to travel reverse. In a second operating mode, rotational orientation is divided into four intervals. A forward motion will control either the trolley or bridge in the direction of the joystick as a function of the transmitter orientation. In a third operating mode, displacement of the joystick will cause a vector command for the material handling system in the direction the joystick is pressed.
