Arcelor Mittal Coke Car Machine Replacement
Project type
Critical Lift Plan
Location
Zenica, Bosnia and Hercegovina
Replacement of a 357,000 lb (162 t) coke car machine was successfully carried out in a live operational coking plant without any burnout or interruption of the coke battery production.
Key challenges:
Live plant environment with continuous high-temperature operations
Extremely limited working space inside the facility
Precise positioning and alignment of the new machine
Requirement for the main crane to be repositioned twice within the confined factory area
Strict zero-incident safety demands in a hazardous industrial setting
Equipment used:
Primary lift crane: 500 t (1,102,000 lb) crawler crane
Supporting rigging and tailing devices for load control and stability
The complete exchange was executed safely and on schedule in only 10 days, with zero lost-time incidents and full compliance with safety protocols.
