TCB Industrial has been awarded a crane and rigging support scope in support of planned maintenance activities at a Northern California power facility. Heavy lifting and controlled handling of large components are central to hydroelectric maintenance, where access constraints, overhead interferences, and existing infrastructure demand precise execution.

This award reflects TCB’s role in supporting critical maintenance work through engineered lifting solutions, disciplined rigging practices, and coordination within active powerhouse environments.

Scope context and rigging requirements

Powerhouse maintenance frequently involves removal, repositioning, or installation of large components that cannot be handled with permanent hoists alone. These lifts often occur in confined spaces with limited headroom, narrow access paths, and proximity to sensitive equipment.

TCB’s scope includes planning and execution of crane-assisted lifts, internal rigging movements, and controlled set-downs within the powerhouse footprint. Each movement must be executed with defined load paths, stable support conditions, and clear communication between rigging crews and operations personnel.

Planning and lift engineering

Rigging work begins long before equipment arrives onsite. TCB’s approach emphasizes preplanning to identify pick weights, center-of-gravity considerations, lift radii, and clearance constraints. This includes evaluating whether lifts will be executed using mobile cranes, internal hoists, or hybrid methods combining multiple handling systems.

Lift planning documentation is developed commensurate with risk level, ensuring all crew members understand the sequence, communication protocols, and stop-work authority. Where lifts interface with existing structures or overhead systems, clearances are verified to prevent unintended contact or load transfer.

Execution in active facilities

Powerhouse environments often remain partially operational during maintenance windows, requiring heightened awareness of concurrent activities and personnel movement. TCB will establish controlled work zones, designate signalers, and coordinate timing with facility staff to avoid conflicting operations.

Rigging execution focuses on slow, deliberate movement rather than speed. Load stability, controlled travel paths, and predictable motion are prioritized to protect both personnel and equipment. When components are positioned, loads are transferred only after confirming stable bearing conditions and proper alignment.

Safety and risk management

Heavy rigging introduces hazards including suspended loads, pinch points, and dynamic load shifts. TCB’s safety controls include exclusion zones beneath lifts, redundant communication methods, and clear assignment of responsibilities. All personnel involved in rigging activities are briefed on the specific hazards and sequence of operations before work begins.

Tool control, housekeeping, and clear walkways are maintained to reduce secondary risks during lift execution.

What this award represents

This project demonstrates TCB’s capability to support complex hydroelectric maintenance through disciplined rigging and crane operations. By combining detailed planning with field execution experience, TCB helps ensure maintenance activities are completed safely, efficiently, and without unintended impact to surrounding systems.
