National Recycling was awarded a contract to dismantle and remove three (3) transformers that were part of a substation. The transformers consisted of (2) 30,000 KVA along with (1) 25,000 KVA.
This job presented particular challenges, as the transformers were located in inaccessible locations for removal purposes. All (3) transformers were stationed 20 feet above ground level and 75 feet away from the nearest access point. National Recycling was requested to present a removal strategy for this unique circumstance. We devised a plan to create temporary access to the transformers.
Items Removed:
- (2) Large Transformers- 30,000 KVA with a total weight of 125,000lbs per transformer-
- (1) Large Transformer- 25,000 KVA with a total weight of 90,000 lbs
- Oil Removal- National Recycling Inc. was responsible for oil drainage, disposal and testing. Oil tests showed less than 5 PPM of PCB’s. National Recycling commissioned a fully licensed oil drainage company to remove and dispose of the oil. A waste manifest was provided.
Removal Method:
- Commissioning a 200 ton Crane- required to safely lift each transformer-
- An oversized crane was required to accommodate for the inaccessible location of the transformers
- Commissioning an excavator- the structure in front of the transformer had to be removed to facilitate a temporary access point- this was done with the assistance of an excavator and a ground compactor
- Arranging Transport- dismantling on site was permitted by the client- (6) Tri-Axle flatbeds were required to transport the transformers
