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 […]
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.
Almost all mounting brackets are available in two variants. The first pivots, the second is fixed. At this point, many design engineers wonder when they should use the pivoting and when the fixed version. Pivoting mounting brackets are standard for gliding or horizontally unsupported applications But why is that? The pivoting mounting bracket compensates for […]
