In the crane engineering industry, energy supply systems prove their technical and economic strengths more and more frequently. Flexibility, variability and space-saving installation are only a few of the most important criteria. Aluminium guide troughs are used for long travels, as they ensure safe guidance under all ambient conditions. Energy supply systems are a compelling choice for crane construction and are being used more and more frequently. They have a number of technical and economic advantages. Compared to conventional systems, there is no need for a cable station.
In this application, it is a crane system for fully automatic operation for storing and retrieving sewage sludge in a cement plant. The designers here were looking for a customised energy supply system together with the matching inner cables.
The crane track has a total length of 32 metres, with a trolley travel speed of 60m/min, a crane travel speed of 80m/min and a lifting speed of 60m/min. The stroke height is also 8 metres.
The energy supply system had to meet requirements in terms of durability and compactness.
The recycling crane now uses polymer energy supply systems that travel in aluminium troughs.
The basic package of the guide trough system consists of only four parts: trough wall, glide bar, clamping shoe and connector. The trough wall made of extruded aluminium is light, yet stable, seawater-resistant and can also be used in harsh environmental conditions. The glide bars are securely clicked into a continuous lateral groove and can be released again. The lower clamp can be installed inside or outside with only one screw on the bottom or on fixing profiles. Finally, a resilient plastic wedge absorbs any shocks that occur.
In addition, there are the chainflex cables with bundle stranding and highly abrasion-resistant, gusset-filled extruded outer jackets, which have been tried and tested for over 15 years, especially in long travels with a high number of cycles, and which meet the requirements of even the toughest applications, as well as mounting elements, strain reliefs and assembly materials.
Altogether, with energy chains including inner cables and the combination with the aluminium troughs, it was possible to implement a system that is as compact as it is space-saving.
