Rubber Tire Gantry (RTG) Collision Avoidance
Challenge
Large, cumbersome shipping containers can block rubber tire gantry crane operators’ view of obstacles on the ground. A reliable sensing solution is needed to detect obstructions in their path and avoid collisions, key to preventing costly damage and downtime.
Solution
Banner’s radar sensors provide reliable obstacle detection for collision avoidance of RTG port cranes. The Q120RA-AF2 Sensor is an advanced radar technology with a narrow beam pattern, high sensitivity, and long range to help detect obstacles in the way of the RTG.
The R-GAGE sensor emits a well-defined beam of high-frequency radio waves from an internal antenna. Some of this emitted energy is reflected back to the receiving antenna. Signal processing electronics determine the distance from the sensor to the object based on the time delay of the return signal, allowing for reliable obstacle detection.
The R-Gage Q120RA-AF2 operates in Industrial, Scientific, and Medical (ISM) telecommunication band with no special licensing required. The rugged housing is rated to IP67 to withstand harsh environments and works in a range from 1 m to over 40 m.
