BLM ship crane thyristor control troubleshooting
 

Four BLM cranes - 4GE-C3 successfully repaired by Alatas.

The BLM cranes are fully electric cranes with a Thyristor controlled drive system. The owner had engaged numerous contractors, electric workshop and crane technicians over the past couple of months, but none was able to troubleshoot and repair these cranes.

ALATAS was called for help. Our specialized BLM experts had no trouble identifying the problem, our spare parts specialists supplied the required spare parts and the cranes were fixed!
