As part of an extensive program to improve the reliability of its facilities, a major hydroelectric energy company tasked Fives Services Inc. with the complete modernization of six overhead cranes used in the maintenance of turbines and alternators.
These systems, installed for over twenty years, faced recurring issues: mechanical wear, outdated controls, lack of precision, and frequent production downtimes.
Objective: The goal was to bring all systems to a performance level equivalent to that of new equipment, while minimizing operational disruptions.
Implemented Solution
The teams at Fives Services Inc. first conducted a comprehensive technical audit to assess the structural and electrical condition of each crane.
Following this analysis, a modernization plan was developed, which included:
-
Replacement of the hoist motors and lifting and translation drives
-
Installation of SMARTLift sensors for real-time monitoring of loads and usage cycles
-
Overhaul of the electrical panels and update of the control schematics
-
Complete refurbishment of the hoists and braking systems
-
Full revalidation of safety systems and emergency stop devices
Thanks to a tight schedule and the involvement of a multidisciplinary team, the work was completed in just fourteen days without compromising safety or production.
Results Achieved
The modernization led to measurable gains immediately upon the equipment’s return to service:
-
30% reduction in unplanned downtime
-
15% improvement in lifting precision
-
Full compliance with current CSA and ISO standards
-
Estimated 10 to 15-year extension of the equipment’s useful lifespan
The modernized cranes now feature an integrated diagnostic system that allows continuous monitoring of usage cycles and maintenance interventions, ensuring optimal long-term performance.
