Bigge Uses Enerpac Strand Jacks to Lift Pier Bridge Tables

Jun 1 2018

In April of 2018, Bigge performed a lift for the Gerald Desmond Replacement Bridge Project in Long Beach, CA. To execute the lift, the Bigge team used four Enerpac HSL50006 strand jacks with 48 strands each to lift the tables over 100 feet in approximately 10 hours. The Enerpac HSL50006 is a 500 metric ton strand jack system that uses heavy lift technology to do lifts synchronically. An operator can communicate  to the strand jack via computer and has the ability to automate locking and unlocking during an operation. 

Bigge lifted the 1.35-million-pound pier tables for each of the two towers on both ends of the new bridge. The synchronized strand jacks permitted the bridge construction team to precisely make this a heavy lift ensuring level and flawless placement of the structure. The new Gerald Desmond Bridge will become the second tallest cable stayed bridge in the United States upon its completion at the end of 2019.
