Seamless (Joint-Free) Conductor Rails
50–170 A · joint-free copper · 99.99% conductivity
A PVC-insulated, joint-free conductor system with continuous copper conductors — available as 3-, 4- or 6-pole versions. There is no air gap at the joint, giving strong pressure resistance, reliable conductivity, easy installation and a long service life.
Minimum bending radius of 750 mm makes it suitable for curved, arc and inclined travel routes.

Other Conductor Rails

Single-Pole Conductor Rails❯
160–3000 A · aluminium or copper conductor · IP23 safety design. A 6101 aluminium or copper conductor in a polymer insulation sheath delivers low-loss, shock-safe power to cranes, hoists and monorails.

Multipole Conductor Rails❯
Multi-conductor in one housing · fewest joints · fastest installation. Several conductors share one insulated housing — saving space, cutting installation time and giving far higher stiffness than single-pole rails.

Tubular Conductor Rails❯
50–210 A · copper core · saves 15–20% energy. Extruded copper conductors in a high-polymer polyethylene sheath, served by a flexible multipole collector — compact, safe and 15–20% more energy-efficient than steel rails.

U-Shaped Conductor Rails❯
100 / 120 A · T2 copper · any pole combination. A T2 copper conductor with high-quality PVC insulation gives excellent insulation and safety; U-shaped rails combine freely for any pole layout with a minimal footprint.

Steel-Body & Steel-Aluminium Conductor Rails❯
400–3200 A · up to +150 °C · for steelmaking & ports. A copper or steel-aluminium composite conductor in a high-strength insulated support channel, mounted on the crane runway to power the moving machine.
