摘要： This invention is applied to a case in which a hanging load 80 is vertically hung and released with a crane having either a jib (60) or a boom (61) which can be raised or fallen. This invention is also applied to a case in which the long hanging load 80 is raised from its fallen state to its vertical state so as to be hung-up and released. A control device of the present invention has a control means for performing automatically the raising of the jib 60 or boom 61 and the winding-up or - down of the winding-up rope 70 in cooperation with each other in response to their initial states. In case that the initial angle of the jib (60) or boom (61) is large or small, it is controlled in such a way as a rate of variation of the hanging load (80) ΔT applied to the winding-up rope 70 becomes constant and then it has means for positioning the extreme end of the jib (60) or boom (61) on the vertical line passing through a center of gravity of the hanging load (80). With such a control device as above, the hanging load (80) is not oscillated and a smooth vertical releasing is carried out. An entire long hanging load 80 is vertically hung up and released from the ground after its vertical releasing without displacing the position of the other end from its fallen state.
摘要翻译：本发明适用于悬吊装置81垂直悬挂并用具有可升起或下降的起重臂或起重臂的起重机释放的情况。本发明还适用于长吊挂81从其下降状态升高到垂直状态以便被挂起并释放的情况。本发明的控制装置具有控制装置，用于响应于它们的初始状态自动地执行起重臂60或吊杆61的升起以及联结起来的卷绕绳索70的卷绕。在起重臂或起重臂的初始角度大或小的情况下，其被控制为施加到卷绕绳索70的悬挂载荷DELTA T的变化率变得恒定，然后具有用于将起重臂或吊杆的末端定位在通过悬挂载荷的重心的垂直线上。通过上述这样的控制装置，悬挂载荷不会振荡，并且执行平滑的垂直释放。整个长悬挂装置81在其垂直释放之后垂直悬挂并从地面释放，而不会使另一端的位置从其下落状态移位。

摘要： Herein described is a method and apparatus for controlling braking and stopping of the slewing of an upper slewing body which is slewingably provided on a construction and hoists a load, represented by a rotary crane, wherein the braking torque for braking the upper slewing body and the braking torque for braking a hoisting load are separately obtained by the calculated slewing angular acceleration, and the whole braking torque is calculated on the basis of both the braking torques, thereby achieving a high accurate control of the slewing stop.
