VAHLE Conductor Rails with Copper Head are electrical power supply systems designed to provide continuous, safe, and reliable energy to mobile industrial equipment. Originally developed by Paul Vahle in 1912, this system became a standard in lifting, transport, and material handling applications.
Their design combines a supporting profile (steel, aluminum, fiberglass, or copper) with a high-conductivity copper head, ensuring optimal electrical contact, minimal contact resistance, and a significant reduction in wear on both the conductor and the current collector.
These conductor rails are capable of transmitting high current ratings, reaching up to 1500 A, with the possibility of increasing capacity through parallel power feeds. The system is characterized by its long service life, low maintenance requirements, and excellent performance under mechanical stress and intensive duty cycles.
Depending on the material of the supporting profile, the rails can be adapted to different operating environments:
Steel with copper head: maximum mechanical strength for heavy-duty applications.
Aluminum with copper head: reduced weight and high electrical efficiency.
Fiberglass with copper head: ideal for corrosive environments or high humidity.
Solid copper: recommended for very high current ratings and severe operating conditions.
Conductor rails with copper head are widely used in overhead cranes, gantry cranes, electric hoists, monorail systems, continuous conveying systems, and port equipment, providing a robust, flexible, and reliable solution for powering mobile industrial systems.
