December 21 - Mammoet has lifted and installed three transformers for Seattle City Light's Denny electrical substation under construction in the USA.
Mammoet hoisted the three 125-ton (113.4-tonne) transformers using a Liebherr LTM 1400.
The long reach of the crane enabled Mammoet to complete the lifting operations and the setting of foundations from a single location. This eliminated crane movements, which Mammoet says saved time in the execution.
The installation of four metal clad capacitor banks was also completed by Mammoet. As overhead obstructions prevented the banks from being directly lifted into place, they were hoisted onto a jack and slide rail system, from which they were set onto the foundations.
According to Mammoet, the Denny Substation, when completed, will be one of the largest developed by Seattle City Light. It is scheduled to be energised in early 2018.
