Rubber-tired gantry cranes are not rail-bound and can therefore switch between container aisles. VAHLE's revolutionary eRTG system ensures efficient power transmission and flexible data communication in the container block.
Rubber-tired gantry cranes are not rail-bound and can therefore switch between container aisles. VAHLE's revolutionary eRTG system ensures efficient power transmission and flexible data communication in the container block.
Rubber-tyred gantry cranes (RTGs) do not require a guide rail. They can switch between different container aisles and are therefore particularly flexible.
Electrification of RTG cranes using conductor rails has been state-of-the-art for some time because it is more sustainable and reduces maintenance and operating costs in the terminal. This is done either by a manual current collector trolley including a plug system, or fully automatically. For this purpose, an automatic telescopic arm engages in the conductor rail, via which the system is supplied with power and data. High transmission rates enable automatic operation via remote desk control and speed up container handling.
To switch between lanes, the hybrid vehicles usually also have a diesel engine on board. However, RTGs could also be equipped with energy storage systems that enable battery-powered block switching.
VAHLE is an expert in the field of port technology. With our revolutionary eRTG system, we have a high-performance solution that has been specially developed for terminals and covers energy supply as well as data transmission and positioning. In this way, we ensure efficient operation inside and outside the container aisles and full control at all times.
Your Vision. Our Solution.
The eRTG system consists of an electric telescopic arm with a current collector trolley that enables automatic retraction and extension into the conductor rail system.
The lightweight U15, U25 and U35 feature an open design that makes them particularly easy to maintain. Available in various conductor materials, they are also flexible and easy to install.
With the SMGX, the proven 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 ensures significantly higher tolerances. The shielded slotted waveguide enables high transmission rates and avoids unwanted interference signals from inside or outside.
APOS Optic can position automatically controlled systems with millimeter accuracy at any time. The simultaneous detection of multiple code fields means that gaps of 40 mm can be safely traversed. Even in demanding environments, the system ensures reliable detection.
Large festoon systems are manufactured individually for the respective requirement. The scalable systems can accommodate round or flat power and data cables.
VAHLE has a variety of spring operated cable reels in its portfolio. They are mechanically driven by steel spiral leaf springs, which makes the systems particularly durable.
VAHLE offers motor powered cable reels of all sizes for the power supply of crane systems in a wide variety of industrial applications for mobile vehicles and loading machines.
