Jack Up System Lifts 1,500-ton Span on Fore River Bridge
No one would call the temporary bridge that was constructed in 2002 over the Fore River between Quincy and Weymouth, Mass., a work of art. The bridge replaced a 1936 Art Deco gem when it could no longer safely carry the 32,000 cars that cross the river each weekday.

Skidding System for Transformer Outage Maintenance
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.

Enerpac helps the Beijing’s "Bird’s Nest" to stand on its own feet
After two years of construction, the main venue for the 2008 Beijing Olympic Games came to a final and most important part of the construction of its steel structure: the dismantling of the temporary support towers. Computer-controlled hydraulics is the perfect match for jobs like this, and Enerpac was granted the contract to perform the stage lifting and lowering of the roof.

Jacking System Slides the Holbrook Canal into Position
Minimizing the amount of time state highway 266 was shut off to traffic was a primary objective during the reconstruction of the bridge structure over Holbrook Canal. Utilizing an innovative Accelerated Bridge Construction (ABC) method Kiewit, Jacobs Engineering and the Colorado Department of Transportation developed a plan to build the replacement bridge adjacent to the existing bridge. The new bridge was initially used as a detour while the deficient bridge was demolished. Once demolished, the new bridge was then closed to traffic and needed to be slid into the position of the original bridge.

Quickly Removing Hundreds of Corroded Carriage Bolts with a Hydraulic Nut Splitter and Cordless Pump
Hundreds of vineyard line posts needed to be disassembled and removed. Many of the nuts had rusted onto the carriage bolt holding the vineyard trellis arms. Unbolting them was very time consuming, and faster removal methods such as grinding or torches were dangerous and posed fire hazards.

Jacking & Skidding a Tunnel Boring Machine for the Next Drilling Phase
In 2013, Jakarta, the capital city of Indonesia, broke ground on a mass rapid transit (MRT) system in hope to alleviate the city’s traffic congestion. The rail-based MRT is expected to stretch across over 108 kilometers. A tunnel boring machine (TBM) is being used to construct the underground routes. One of the critical phases of the tunnel construction is the pass through, in which the TBM needs to be moved through the underground stations to be relocated to the next drilling position.
