BTG Transponder based absolute Measurement Systems at both RTG Crane legs
The RFM220 is an absolute and continuous measurement system based on transponder technology (RFID) and is especially designed for positioning of Rubber Tired Gantry Cranes (RTG) in a heavy duty environment with up to 10 mm accuracy.
The system uses a 134 kHz. programmable transponder, which is programmed with its exact position related to a chosen reference point. The transponder will be installed easily in the ground and works battery-less. The system charges a transponder within its measurement range, reads out its code and determines the position of the transponder under the system.
The systems provides the exact location of both crane legs with a accuracy of 10 mm by knowing the absolute position of the transponders and the relative position of the transponders underneath the RFM220 antenna. This information makes autosteering the RTG very easy and makes it possible to fully automate the RTG.
BTG is worldwide the leading company for AGV position measurement in the automated Ports.
