Durapac Hydraulic: DANGER (Overhead) High Voltage!
For this transformer change out four RG-258 Durapac 25 ton cylinders with stabilising bases, four-way manifold and electric pump were required to manoeuvre the transformer into position.
The transformer was loaded onto rated I-beams which were slowly driven into the yard with a remote-controlled caterpillar track machine.
30-ton load skates were used to manoeuvre the transformer into position.
Then the four Durapac RG-258 cylinders and four VCV-66 four-way manifolds were used to carefully lower the transformer onto the final resting position on the concrete pad.
This method was much more economical than hiring expensive overhead cranes, considering the high overhead lines in the substation.
