Indication: Real time display of the tower crane tower arm position, small amplitude (for boom type tower crane is the arm of the inclination and arm tip amplitude).
Alarm: Visual-audible pre-alarm when the load or radius reaches pre set pre-alarm point; Visual-audible alarm when the load or radius reaches pre set alarm point; when one set in the network go wrong, the alarm light at the top of cabin(option) will give alarm.
Anti-collision: According to the real time positions of tower cranes, allow or prohibit the movement of trolley and slewing. Including 11contacts: 4contacts for trolley (high speed forward, low speed forward, high speed backward, low speed backward); 7contacts for slewing (left high speed, left low speed, right high speed, right low speed, left inverse ejecting, right inverse ejecting, braking).
Wireless Communication: Each controller can communicate wirelessly among tower cranes and accomplish anti-collision and zone protection. Each controller could be added or quit the network effecting without other tower cranes’ work.
Data Set and Wirelessly Upload: All the data about site, tower crane and zone could be set on the computer in the office and wirelessly upload them to each controller on the tower crane.
Sensors Calibration: Calibration and measurement could be achieved by several simple operations after installation.
Records of controlling: All the records of controlling can be stored in the controller, which can be downloaded to surveillance computer for checking.
Updating of load chart of tower crane: Tower crane controller can record control action, and can be controlled history data read out to the monitoring computer to browse.
Authorization of Operation: In case of unauthorized operation, an authorized password is required for data setting and operation.
