Energy chains
For many lifting applications, a compact and space-saving solution is extremely important. However, the more cables have to be routed together in a system and the longer the lifting height, the less the choice of possible solutions. When the already presented liftband or e-spool reach their technical limits, the only thing left is the so-called zig-zag installation method.
Energy chain systems offer a space-saving alternative for the cable routing on the slewing gear. The chain is guided lying on its side with the help of a round guide trough. In this way, angles of rotation of up to 540 ° and speeds of rotation of up to 360 °/s can be achieved.
The new igus P41.80RI roller chain with integrated iglidur plain bearings has been doing its job on the gigantic ship unloader cranes from EMO B.V. in Rotterdam since the end of 2015. EMO B.V. is one of the largest bulk terminals in Western Europe. With a trolley travel of over 100 m, a travel speed of up to 4 m/sec and an additional load of over 50 kg/m, it is one of the most demanding energy chain applications in the port crane sector.
The e-spool is a chain-based drum application without a slip ring. Ideal for applications and lifting devices that have no space for a collection basket (lift band). The cables routed in the chain are not exposed to tensile stress, which has a positive effect on the service life of the cables.
The lift band was specially developed for vertical applications on indoor / EOT cranes. A spiral energy chain that can be stored in a collecting basket. The cables are routed through the spiral energy chain without being exposed to any tensile stress. The retainer belts attached to the system ensure that the energy chain is safely stored in the special basket. The system is light, requires very little space on the lifting device and it is almost maintenance-free.
