Overhead crane conductor bars are crucial structures that enable consistent power flow to internal and auxiliary crane functions. Conductor bars are precisely engineered to maximize safety and rates of power delivery.
The diverse operational applications of cranes mean power systems need to be versatile. A capacity for broad adaptation ensures the equipment can account for many different project variables. Therefore, conducting system options are designed with durability, mounting variability, heat dissipation, insulation, and ease of installation held at high priority.
Crane Conductor Bars
Crane conductor bars are constituted by a multi-part system working in unison.
A summary of conductor bar elements:
- Conductor Bar
- Collector
- Hangers
- Brackets
- Anchor Clamp
- End Cover
- Power Feed
The primary conductor bar supplies and guides power along the crane bridge. A collector unit processes the delivered current and feeds it into the various crane machines. Hangers connect a series of supportive brackets along the runway to the conductor bar itself. An anchor clamp may be implemented to modulate conductor movement during thermal expansions or contractions. The end of the conductor bar is capped by an end cover to provide safety and a cut-off to the flow of electrical current.
Conductors are built for efficiency, ease of installation, and longevity. In addition, they’re compatible with a large variety of subparts (such as brackets and hangers) – enabling simple, efficient maintenance.
A primary advantage to conductor bars is their viability in multi-bridge runway systems. In addition, conductor bars may be adjusted to suit indoor and outdoor cranes and perfectly accommodate low ceiling environments with limited dropdown power cable spacing.
Because of their versatility, conductor bars are ideal for regularly upgraded systems or in retrofitting legacy operations. Power continuity between existing and new interlocking elements can be trivialized by introducing an appropriate conductor unit. In addition, the straightforward installation allows runways to be extended without excessive logistical challenges related to power supplies – cutting project lead times.
Related Overhead Crane Systems & Components
Industrial overhead cranes can be equipped with a wide variety of accessories and modifications. Implements include:
- Bare and insulated conductor bars. Bare options provide significant cost reductions in large-scale applications, whereas insulation increases operative efficiency and safety.
- Spring and motorized cables/hose reels. Cable reels are intended to deliver power to the various industrial elements on a crane. Spring designs enable high power extension and retraction of the reel.
- Festoon systems. Mobile supports for power cables that allow smooth, dynamic movement with trolleys or hoists.
- Slip ring assemblies. Facilitates sensor interactivity and transfer of electric current from stationary to rotating / mobile elements.
Additionally, highly tuned optical positioning systems (OPS) may be employed to provide real-time feedback on machinery spacing, movement, and relative component locations. Positional awareness is a valuable tool for autonomous material management and programmed crane operation. OPS elements can be custom configured to new and existing overhead crane operations.
