Introduction:

The customer reached out to Alatas for help with their crane, which was experiencing issues with hoisting up or down.

Background:

After a brief period of being parked, the crane was unable to operate the hoist system when attempted for further use.

Alatas’ Solution:

Upon inspection, Alatas identified a fault with a contactor, preventing the hoist system’s Simoreg drive from receiving an enable signal. This issue was pinpointed by analyzing the logic within the S5 program to identify the malfunctioning contactor. After removing, manually testing, and reinstalling the contactor, the crane resumed normal operation. Additionally, new parts were provided to the customer to enhance the crane’s reliability in the future.

Job Scope:

  • Diagnose the hoisting issue with the crane.
  • Restore functionality to the crane.
  • Advise on necessary spare parts for improved reliability.
