Open conductor systems

Open conductor rail systems are a safe source of power for current capacities up to 3000 A for many power loads that are predominantly subjected to rough operation, e.g., traveling cranes, loading bridges, container handling equipment, monorail systems, coking machinery, electric hoists, etc.

Special features

  • Variation in temperature and resulting expansion and contraction is compensated by standard expansion joints.
  • Conductor rails can be delivered already bent.
  • Heating systems are available for all conductor rails.
  • Special conductors for up to 3000 A current capacity are available on request.



Insulated Conductor System U10

The insulated conductor system U 10 is a conductor rail used for supplying main power and signal current, as well as data transmission (Powercom), especially for monorail systems. Slip rings and multipole slipring units also present no problems.
Capacity: 10 - 100 A.


Insulated Conductor System U15, U25, U35

U15, U25, U35 are single-phase, insulated conductor rails for use in cranes (overhead cranes, loading bridges, etc.), monorail systems, AS/RS systems, elevator systems, sliding doors, data and signal transmission, amusement rides, high-voltage installations, conductor rail trench systems, and many more, for a current consumption of
10 to 1250 A.


Compact Conductor Systems VKS 10  &  VKS

VKS is a space saving conductor system, designed to prevent accidental touch to regulations VDE 0470 part 1 (EN 60529). It consists of a flat PVC housing and pure copper or stainless steel conductors. The minimum space required allows the system to be integrated in the crane or hoist track. Multipole systems with 3, 4, or 6 conductors are available and several housings can be easily combined to get as many conductors as required. VKS can be used for indoor and roof-over (rain-protected) applications. The system is designed for hoists, stacker cranes, monorails, machine tools, testing lines and many other types of mobile equipment. The PVC housing holds 3 - 6 conductors for power supply and control functions.

VKS 10 is a compact, safe conductor system protected from contact in accordance with DIN VDE 0470 Part 1 (EN60529). It consists of a flat insulating housing, in which the conductor rails are held. This flat construction allows the direct placement in half profiles and VAHLE carrier profiles. In connection with the newly developed HRL carrier profile, hanging distances up to 4.5 m can be realized without expensive auxiliary structures. According to the phase configuration, in addition to the power supply, there are still 3-6 other conductors available for transmitting signal currents. In addition, the system permits the economical integration of various path-coding systems. With these properties, the VKS 10 system is excellently suited for automatic stackers. It is to be used only for indoor installations and for horizontal arrangements in straight tracks. 


Enclosed Conductor System KBH

The KBH is a powerail, protected from contact (IP 23), for indoor and outdoor plants. They are conductor lines in a rigid grey PVC housing with different copper cross sections for rated currents of 40 - 200A. The current collectors, running in ball bearings, are guided by the housing. The main is transferred by spring-stored carbon brushes.

Compact arrangement, corrosion resistance, and simple assembly are the essential features. The KBH is suitable especially for overhead and elongated tracks for cranes, monorails, electric hoists, electric tools, stacking systems, as well as many other applications for supplying power to moving power loads.
