The present invention Beyond this by setting the initial operating radius of operation during the boom of the crane By mounting a GPS module for positioning the boom of the jib crane (Boom) end so that you can keep track of the revolution and the height position of the boom crane was this to automatically stop, especially when lifting things in the docks repeatedly setting once the turn and pitch position of the boom can be automatically driving the boom until the end of the working jib, that could reduce the working fatigue cranes It relates to a control device.
To this end the present invention is the control panel for driving at least three satellites from being equipped with a GPS module with a GPS receiver for receiving GPS signals, and the turning and height adjusting the boom hoist to the boom tip of the jib crane has the GPS module the distance and time to the latitude, calculating the longitude and altitude from the boom position storage unit for storing the boom position calculation, safety coordinate and time, and end point coordinates to convert three-dimensional coordinates, said comparison determining the stored coordinates and real-time coordinate to the boom position comparison send control signals to control the boom and a hoist so that the control part is provided, the boom safety position where the boom remote controller has a remote control for the control panel to the wireless setting the safety coordinate avoid collision with an obstacle in the working group grounds additional settings are provided, the same time there is the boom boom-part feature coordinates and sets the repeat interval to set the start point and end point coordinates to automatically round to the same end point coordinates of the work area.
