cable trunking system / metal / for conductor rails

The totally enclosed VAHLE Conductor Rail Trunking Systems have been manufactered since 1925. It is used at dockside cranes, loading bridges, container handling equipment etc. in which overhead installed conductors would be hindering. The ducting system is installed in parallel to the crane track below or above ground and could be adjusted without difficulties to all occuring curves of the crane track.

The flush-mounted version is normaly installed in a concrete trench, while in the surface-mounted version the trunking is made of steel. Both cases are entirely covered by steel-plates resting on both sides of the ducting, one side being hinged with negative or surface hinges.

The plates facilitate walking and the system can be used as a pavement in harbours or loading areas. If the duct should be walkable negative hinges are recommended to prevent risk of stumbling.

While driving the crane the cover plates are lifted by the cover plate lifting device only to let the feed cable through.

For maintenance of the conductor rails and collectors single covers could be lifted by simple tools.

Unallowed individual lifting by hand is prevent due to the heavy weight of the plates. This is aswell valid for cover plates lifted by the cover plate lifting device due to a safety arrangement.

A practically unlimited number of cranes or other machinery can be supplied by this conductor duct system. It is aswell possible to add at a later date additional cranes, assuming that the cross section of the conductor is suitable for this.

An extention is possible to both sides of the system.
