Skidding System for Transformer Outage Maintenance

Customer

Challenge

The Bonneville Power Administration needs to maneuver and replace transformers at their power plants and stations during outages. During an outage, the maintenance team often needs to replace a transformer. Their existing process for replacing a transformer required multiple workers operating different pieces of equipment in coordination. BPA was seeking equipment to simplify and improve the safety of their current process.

Solution

A custom hydraulic skidding system will provide the maintenance team with the ability to maneuver and transport transformers with physical access limitations. The skidding system is comprised of two custom RD-Series push pull hydraulic cylinders, two ZE4 hydraulic pumps and a low height skid track and support beams. Both power units are connected together to provide synchronous travel of the load. The skid track’s support system reduces setup time by enabling spanning of unsupported gaps between crib stacks. The hydraulic system provides a single operator the ability to precisely, and safely position their heaviest transformers with a push button control.
