Electrifying RTG cranes helps reduce fuel consumption, support automation and meet port sustainability goals. VAHLE Inc. delivers turnkey conductor rail, data and positioning systems — built for coastal durability and automation-ready performance.
Rubber-tired gantry (RTG) cranes are key to flexible yard operations in container terminals. Their mobility between container aisles makes them ideal for high-throughput, dynamic stacking operations — but traditionally, that flexibility came at the cost of high maintenance and increased emissions.
Modern electrified RTG (eRTG) systems help U.S. terminals reduce operating costs, improve sustainability and enable automation. VAHLE Inc. provides fully integrated electrification systems — combining continuous power delivery, high-speed data communication and precise crane positioning — engineered for demanding port environments and high-duty cycles.
RTG electrification is typically implemented using conductor rail systems. VAHLE supports multiple configurations, including a manual plug-in collector concept, a semi-automatic arm system or a fully automatic power solution using telescoping connectors to supply continuous power and enable integrated data transmission. These high transmission capacity systems enable RTGs to operate continuously in fixed aisles while supporting remote control, real-time monitoring and safety-critical data transmission.
For terminals requiring aisle switching, our RTG systems support battery-powered block changes with energy storage systems as well as hybrid RTG configurations. VAHLE’s eRTG solutions are modular, automation-ready and scalable to terminal size and layout — helping port operators reduce emissions, increase crane uptime and comply with emerging environmental regulations.
Your Vision. Our Solution.
Large cable festoon systems are manufactured individually for the respective requirement. The scalable systems can accommodate round or flat power and data cables.
VAHLE offers motorized cable reels of all sizes for the power supply of crane systems in a wide range of industrial applications for mobile vehicles and loading machines.
With the SMGX, the tried-and-tested SMGM system has been adapted for outdoor use. It is based on the functional principle of the SMGM, but has particularly robust mechanical components and also guarantees significantly higher tolerances. The shielded slotted waveguide enables high transmission rates and prevents unwanted interference signals from inside or outside.
With the CPS 20, VAHLE has a sophisticated and field-proven solution for inductive power supply in its range. Crane systems, heavy automated guided vehicles (AGVs) and applications with high power ranges are reliably supplied with energy.
The lightweight types U15, U25 and U35 are particularly easy to maintain thanks to their open design. Thanks to different conductor materials, they are also particularly flexible to install.
