Introduction

Doyle Shipping Group requested ALATAS to replace damaged wiring and perform additional fault finding to get the crane operational again.

Background

Insulation was damaged and missing from wires inside electrical panels x1 and x2. The crane had been parked for 4 years. Since April, the customer has been unable to start the crane due to CAN BUS faults.

ALATAS’ Solution

All damaged wiring was replaced with new cables matching Liebherr’s original specifications. We then conducted troubleshooting on the control system’s CAN lines 1 and 2. The crane is now operational.

Job Scope

  • Replace damaged wiring.
  • Conduct fault finding.
