| The tower crane in the use process, as a result of its own unique feature, moves the operating mode to its use process into carry on the safe monitor has the necessity very much. Under each kind of operating mode makes the accurate safe response to the tower crane various spots stress strain, and promptly takes the corresponding measure, this to guaranteed the tower crane movement security, the protection tower crane operator safety has the extremely vital significance.In the recent ten years, the overseas tower crane researcher has done the massive research and the technical change to the tower crane safe supervisory system, and has promoted the performance superior, the early warning prompt tower crane special-purpose PLC control and the entire parameter intelligence control and the breakdown diagnosis system, but our country just started in this aspect research and development, because the control system reliability was bad, it caused the tower crane to appear the high cranery, the electric appliance accident rate in the use process. Therefore the development tower crane synchronization operating mode safe monitor early warning system becomes the tower crane profession urgent matter.
