Title:
AUTOMATIC ANGLE CONTROL SYSTEM OF TOWER CRANE SUSPENDED LOAD AND AUTOMATIC ANGLE CONTROL METHOD
Document Type and Number:
Japanese Patent JP2021169349
Kind Code:
A
Abstract:
To provide an automatic angle control system of a tower crane suspended load and an automatic angle control method which automatically adjust the suspended load lifted by the tower crane to a desired position and angle with a simple method, and improve safety and working efficiency.SOLUTION: A suspended load 7 is suspended from a tower crane 2 via an automatic angle control device 4. An automatic angle control system of a tower crane suspended load acquires continuous three-dimensional position information of the suspended load 7 in real time, which is transmitted from multiple satellite positioning antennae 5 provided on the automatic angle control device 4. The system adjusts the elevation angle of the suspended load based on the three-dimensional position information, adjusts it to the elevation angle of the suspended load mounting position, moves the suspended load above a suspended load mounting position 6 while keeping a suspended load azimuth angle, calculates the suspended load azimuth angle of the suspended load 7, and aligns it with the azimuth angle of the suspended load mounting position at the suspended load mounting position 6.SELECTED DRAWING: Figure 1
