Energy supply
In the case of indoor cranes, the main power supply is usually provided via busbar systems and data transmission via wireless data systems. A drum solution (motor-driven or spring balancer) is generally used for large or harbour crane systems. Information about the drum solution can be found in the article with the title: Harbour / Large Crane Main Power and Data Supply.
Flawless transport systems are conquering more and more areas of industry – intralogistics in particular. These small and large automatic guided vehicles, or AGVs, have one thing in common: they must function reliably 24 hour a day, seven days a week – ideally for a long period of time. Periodic maintenance is not desirable. That […]
How can energy supply systems be made ready to plug and play? The more complex the system, the more extensive the functions of the machine, and the more effort and cost often associated with the energy chain. For this reason, complex systems often require many plug-in points that must be produced and coded according to polarisation – the ideal solution is the Module Connect adapter.
Discussions of strain relief frequently include references to relative motion. Consideration of this motion is the basis for optimum strain relief. If a cable is on the energy supply’s neutral axis, the cable length is the indicated chain length. However, there is often one cable in the inner radius and one in the outer radius […]
Modern energy chain systems can achieve travels of 1,000 metres and more. But long travels are just where it is difficult to ensure that the guide trough is mounted exactly parallel to the crane rail, for instance. Deviations of more than +/-5 mm over a distance of 100 metres and more are difficult to avoid. To ensure that the energy chain runs over itself cleanly on the two outer belts even on long travels, a compensation unit was developed.
