Enerpac has gained unique expertise in delivering hydraulic solutions for the controlled movement and positioning of structures.

Maintenance on the Neeltje Jans storm surge barrier with Enerpac torque
Maintenance on the Neeltje Jans storm surge barrier with Enerpac torque

Maintenance of the hydraulic cylinders in the Neeltje Jans storm surge barrier's sluices that enable controlled opening and closing of the heavy sluice-gates.  After being exposed to the elements for many decades, the 85mm bolts on the cylinder heads can only be loosened and tightened in a controlled manner with breakaway torques.

Bearing Removal on NASA's Crawler-Transporter
Bearing Removal on NASA's Crawler-Transporter

Built in 1965, NASA’s crawler-transporters have carried rockets and spacecraft to the Kennedy Space Center launch pad for more than 40 years. The crawler-transporters will continue to be critical elements for future launch operations; however modifications are required in order to transport a rocket and launch tower combination heavier than the Saturn V moon rockets the crawlers were designed for.

Offloading a 1,300 ton Hydrocracker
Offloading a 1,300 ton Hydrocracker

Beluga was tasked with offloading a hydrocracker weighing 1,306 tons from a barge and bringing it onshore. Due to the weight and length of the hydrocracker utilizing a crane was not an option.

Lifting a Coker for Base Repair Maintenance
Lifting a Coker for Base Repair Maintenance

The base below a coker at a refinery in the Oil Sands needed to be repaired in order to stabilize the foundation. In order to perform the base repair maintenance the massive vessel needed to be lifted approximately 100 mm. Lifting a vessel weighing 600 tons, 9m in diameter and 40m tall required a solution with a high degree of safety, capable of maintaining the balance of the load throughout the lift.

Modular Low-Height Skidding System Speeds Up Move of 85 ton Ceramic Press
Modular Low-Height Skidding System Speeds Up Move of 85 ton Ceramic Press

The ability to quickly lay and relay the Enerpac LH400 low-height skidding system in different directions has allowed leading Middle Eastern heavy lifting company, Al Faris Group, to complete the move of large ceramic presses in record time.

Box Girder Launching System on the I-95 Whittier Bridge
Box Girder Launching System on the I-95 Whittier Bridge

Constructed in 1951, the John Greenleaf Whittier Bridge is currently in the process of being replaced by a new bridge compliant with current safety standards. The high traffic bridge connects Newburyport and Amesbury via I-95 over the Merrimack River. Walsh Construction is employing a rail mounted gantry crane system to simplify the placement of the steel bridge girders and precast deck to create the approach spans. Two 6 foot tall, 960 foot long temporary support steel box girders will be launched across temporary piers to create a rail system for the gantry crane to operate on during the approach span construction. The steel box girder arrangement will be moved after the placement of each approach span. It’s critical that the two 550 ton temporary steel support box girders move in unison in order to prevent binding or misalignment of the gantry crane operating on top of the rail system.

Lifting a Historic Building for Renovation
Lifting a Historic Building for Renovation

Renovation of a historic building in Georgia's capital required the foundation to be repaired after it had sunk into the ground. The 100-year-old building needed to be lifted 3.4 meters onto pylons in order to be renovated.

Synchronous Lifting Pump and High Tonnage Cylinders Steady the Ship for Seaspan
Synchronous Lifting Pump and High Tonnage Cylinders Steady the Ship for Seaspan

Effective, safe, and precise movement of such a large and heavy object requires exact control and synchronized movement of all lifting points. To achieve this, an Enerpac EVO Synchronous Lifting Pump and 12 High Tonnage Hydraulic Lifting Cylinders were specified and supplied by local Enerpac distributor Hyseco.

Hydraulic Drive System for Las Vegas Observation Wheel
Hydraulic Drive System for Las Vegas Observation Wheel

Erecting the Las Vegas High Roller Observation Wheel included installing the 28 passenger cabins. To ensure accurate and safe installation, a hydraulic drive system was needed to turn the wheel for correct positioning and placement. The drive system would also be critical in the overall rotation of the wheel, which would serve as the permanent operating system. Enerpac and Schwager Davis Inc., a specialty contractor, worked together to supply a reliable system solution.

Lifting and Installing the Deck Sections of the Golden Horn Metro Bridge
Lifting and Installing the Deck Sections of the Golden Horn Metro Bridge

The Golden Horn Metro Bridge is a 936 m (3,071 ft.) long cable-stayed bridge which spans the Golden Horn waterway in Istanbul, Turkey. Portions of the bridge deck rotate in order to permit large shipping vessels through the waterway. The rotating bridge deck segments were fabricated off-site and floated in on a barge. The 300 ton deck sections needed to be lifted off the barge nearly 17 meters and installed into position.

Offshore Production Facility Module Load-Out
Offshore Production Facility Module Load-Out

An offshore production facility was constructed in the Gulf of Mexico and is projected to be located in water depths of in excess of 5,000 ft. In order to construct the tension-leg platform several modules weighing approximately 7,000 tons needed to be slid into position.

Lifting the Songdo Cable-Stayed Bridge Pylons
Lifting the Songdo Cable-Stayed Bridge Pylons

Lifting and positioning two 2,000 ton cable-stayed bridge pylons into place. To prevent counter-balance issues, it was critical to erect both pylon sections simultaneously and within a very tight tolerance. Any counter-balance issues would have created a lopsided load and put undue stress on the center pillar. The lack of a good footprint and the approximately 100 meter lifting height made the lift almost impossible for two cranes or another lifting solution. The need to lift from the central point of the structure required a high capacity lifting solution that could raise both sections simultaneously from a central point.
