ZPMC to supply STS & RTG cranes for AD Ports’ projects in Africa
NewsZPMC has won a major contract with AD Ports Group for terminal projects in Africa.
Seoho steers by satellite
Seoho Electric of Korea is offering a GPS-based auto steering system for RTGs. It previously offered auto steering using CCD cameras to capture deviation from a painted line, but in 2001 began developing a GPS system using real-time kinematic (RTK) GPS technology.
RTK (or carrier phase) technology achieves a higher degree of accuracy than “standard” DGPS and calculates position in real-time but is more complicated and, therefore, more expensive. It is, however, becoming more commonplace. Recent examples include a container position system developed by Sanderson Logistics in Australia for Patrick Stevedores’ East Swanson and Port Botany terminals, ZPMC’s RTG auto steering system and Rahco International’s steering system for large stackers at mining sites.
