From practical experience: Rotating tower cranes
Consistently in use: The Liebherr Group with its crane division at the Biberach plant (LBC) has been a client of IGH Automation since 2003. LBC is continuously using our test software in production – from the test stand for the electrical subassemblies of construction cranes to the checking of top-slewing and bottom-slewing cranes, as well as for component test stands in all assembly cycles.
1A testing quality – fast and digital
The amount of work involved for LBC in quality assurance before they used our test software was immense. All subassemblies of the rotating tower cranes had to be transported to the outside area for testing and then assembled. This involved two employees working non-stop for two whole days. The company therefore decided to replace the primarily manual testing with automated testing. Our test software checks the functions of the main subassemblies as early as during production. The test stands simulate all operating conditions and operator actions. This requires just one employee needing only four hours to complete all the work. In addition, all data is recorded automatically and stored in the digital machine protocol.
