Products and services
- Trolley Bus Bar B (Strombahn B) Rugged industrial trolley bus bar with stable steel sheet housing, copper rails open inside for unrestricted thermal expansion, suspension spans up to 3 metres, travel speeds up to 7 m/sec, and IP 50 / IP 53 touch protection. Designed for heavy-duty production lines, final assembly lines, and movable industrial consumers.
- Trolley Bus Bar D (Strombahn D) Compact trolley bus bar with galvanized sheet steel housing, plastic profile inside, indestructible plastic rollers, and double-contact current collectors. Suited for laboratories, schools, workshops, and smaller rooms requiring the most compact trolley bus bar for movable consumers.
- Plug Line S (Stecklinie S) Trunking bus bar system with sendzimir galvanized steel profile and integrated plastic profile for copper conductors, available in nominal currents of 25, 40, or 63 amperes. Collectors can be installed at any point in the line without cutting cables, enabling freely positionable power tap-offs for movable equipment in industrial and laboratory settings.
- Festoon Cable System F (Kabelschleppsysteme F) Cost-effective cable system for transmission of information and energy with five profiled rails for different load classes, optional RAL color coating, and cable trolleys in rotating, fixed, or twin variants. Designed for cranes, overhead cranes, and transport systems, with stainless steel options for electroplating and aggressive atmospheres.
- Switch Bar K (Kontaktband K) Flat, robust, self-monitoring safety switch bar that transmits a signal to the control unit only when damaged or with defined touch. Used for clamping protection of shearing edges and monitoring tasks at gates, self-propelled industrial trucks, production facilities, and filling hoppers to prevent human injury or material damage.
- E-Box Flexible, suspendable socket outlet combinations compatible with Trolley Bus Bar B, Trolley Bus Bar D, Plug Line S, and Festoon Cable System F. Customizable with Schuko or CEE sockets, single or twin casing, with or without lid and compressed air connection, and available in fused, fault current circuit breaker, or combined versions.
