Control system for the manual control of indoor cranes03 October 2017
More crane technology companies rely on modern cable guidance with energy chains. With the new guidefast control system, igus has now developed an energy supply system that can also feed a manual overhead crane pendant on indoor cranes.
Quick and easy to assemble, it needs only a small installation space and can be adapted to suit almost any crane application.
While energy chain systems are becoming the standard for energy supply on port cranes, they are also being increasingly used on indoor cranes. The advantages compared with festoon cables are clear: an energy chain system protects the cables inside it, ensuring they have a minimum bend radius and physical protection. This is also the case for the manual control of indoor cranes, where the new system safely transmits signals via control cables. A trough guides the energy chain and cables, as well as the overhead crane pendant, even with a short-term high tensile load.
As with the guidefast guide trough for the cable guidance of the hoist and trolley for lifting gear, the control can also be installed quickly and easily: in the first step of the assembly, the guide trough is fastened to the side of the crane girder saving space and negating the need for welding. It is then hooked and bolted into the support, which also saves installation time. In operation, the moving end arm can be easily moved and positioned by the overhead crane pendant along the entire crane girder, regardless of the position of the lifting gear thanks to the self-lubricating and maintenance-free xiros polymer ball bearings.
The complete igus control system is independent of the crane manufacturer and therefore can be used with any crane system or operating device both indoors and outdoors. When selecting the cables, igus offers designers a choice of 1,244 different chainflex cables that have been developed specifically for movement in energy chains.
