Heavy Enclosed (Trench) Conductor Systems
First developed in 1925, VAHLE heavy enclosed conductor systems are the proven solution for safe power supply for large material handling equipment such as dockside cranes, loading bridges and container handling systems. It is specifically designed for environments where overhead or bare conductors can present hazards or in situations where space is at a premium.
Underground Conductor System
For heavy-duty underground conductor systems, a concrete trench is installed underground with steel cover plates flush with the ground, with the top of the duct accessible via a series of hinged plates that can be independent or interconnected to form continuous steel ribbon. Conductor rail is installed in the ducting and is connected to the crane via an articulating towing arm that lifts the steel plates while riding along the system. The cover plates can be designed accept heavy traffic including wheel loads.
Any VAHLE conductor rail systems can be installed within the ducting. The overall system can accommodate multiple cranes based on the electrical capacity of the underlying conductor rails.
Above-Ground Heavy Conductor System
VAHLE's surface-mounted ducting system is used in areas where below-ground trenches are not an option. The conductor bars are arranged laterally or upright-mounted at the bottom of the duct. The current collector is built to allow for up to 150mm of misalignment between the crane rail and conductor.
Two basic options of above-ground conductor system are available:
VAHLE's FK system is an above-ground heavy duty steel enclosed conductor system designed for electrification of heavy OHT (overhead hoist transport) cranes, container handling facilities and other installations with movable machinery. The FK system is ideal for confined applications because the collector trolley doesn't require an extra runway.
The VAHLE CP-Crashproof Conductor Line system is a combination of a guide rail and a safety electrification system. Manufactured with steel of a maximum thickness of 12 mm, the U-shaped housing is built to be rain-, snow- and dust-proof, and accidental contact with the enclosed conductors is impossible.
