Energy chains for single-girder travelling cranes

Single girder overhead travelling cranes or single girder bridge cranes are particularly flexible crane types that ensure the lifting and transport of heavy loads, especially in warehouses or production halls.
Due to the wide range of applications for these systems, a customised energy supply solution is required depending on the application. Our energy chain, guide trough and cable are also designed for quick retrofitting, quiet operation and the smallest bend radius.

Cable chain with isense sensor for monitoring movement and condition.

Smart condition monitoring systems i.Sense
The intelligent sensor technology and software i.Sense monitors the condition of the crane's energy chain around the clock. While heavy loads, long operating times and severe weather conditions mean high loads for STS cranes, i.Sense helps to ensure safe operation. In the event of problems, the software can initiate an emergency stop to prevent major damage.

Aluminium guide with two side guide units on a rail.

Super aluminium guide trough
guide troughs are used for long travel distances, from 5 - 12 m depending on the chain type, and support the smooth, low-friction running of the energy chain. The Super-Alu guide troughs consist of a corrosion-resistant and seawater-resistant aluminium profile. They also enable very easy and universal installation.
