Enerpac has gained unique expertise in delivering hydraulic solutions for the controlled movement and positioning of structures.
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.
Lift and Weigh of a Jack-Up Rig Cantilever and Drill Floor
Lamprell has completed the fabrication of a new jack-up drilling rig. Every jack-up rig cantilever and drill floor needs to be accurately weighed after construction. Space restrictions under the cantilever prevented the use of other weighing systems without costly rework to the load structure. Enerpac distributor Al Masaood Trading, based in Dubai, was asked to provide a safe, accurate and compact solution for weighing the jack-up rig cantilever and drill floor.

Pulling Pins on an Oil Well Casing Elevator Spider
The borehole of every oil well drilled must be cased with a durable material to prevent contamination and provide structural support during drilling. An elevator spider is used as a guide to aid in centering each casing. The pin on the elevator spider must be replaced after every drill in order to remove corrosion, dirt and grime built up during drilling. MOISS’s existing process for removing the pin took up to 4 hours and required continuous hammering.

Transporting Reactor Vessel Head Replacement Components
To provide radiation shielding on the bottom of a reactor vessel head assembly, a 14 ft. diameter, 3 ft. thick steel plate needed to be transported through a narrow passage way of the reactor building equipment hatch.
Hydraulic Jacking System Assists Construction of the Honolulu Rail Transit System
In 2012, the Honolulu Rail Transit Project began the construction of a 20-mile elevated rail line. The rail system seeks to alleviate significant traffic issues affecting Hawaii’s most congested city. Kiewit was tasked with the design and construction of the elevated rail guideway. In order to accelerate the construction timeline and maintain a high-level of quality, Kiewit selected a segmental precast span-by-span construction technique to complete the project.
Strand Jacks Smart Cylinder Control System Enable Safe and Synchronous Lowering of Shaft Lining for Underground Mine
The proper installation of shaft lining is crucial to the safety of mine workers.
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.
Assembling and Transporting Electric Transformers with a Hydraulic Gantry
Tadeo Czerweny, a global leader in the electric power transformation market, based in Argentina, was seeking a solution after deciding to expand their manufacturing capacity and build higher-capacity electric transformers. The immediate need was to vertically lift a heavy platform structure used to assemble electric transformer cores and transport the large electric transformers within their plant. The maximum loads to be moved were 250 to 300 metric tons with a total height of 11 meters.
Assembling an Offshore Platform Oil Rig Modules
Petrobras is constructing a new offshore oil platform for an oil field in the Santos Basin off the coast of Rio de Janerio. Jaragua Equipamentos was tasked with assembling 4 modules during the construction of an oil rig. Each module weighed more than 700 tons and required precision lifting and alignment during assembly.

Safe Disposal of Old Gas Cylinders with Hydraulic Punch Set
Before gas cylinders can be disposed of in Australia, they must be completely unusable, to stop people reusing faulty and dangerous cylinders and causing themselves serious harm. The most effective way to do this is to puncture a hole in the cylinder.
Assembling Tower Crane Sections with a Hydraulic Torque Wrench
Numerous joints need to be bolted together during the erection and disassembly of a tower crane. The stability of the tower crane is dependent on the integrity of its bolted sections. The precise application of torque is critical to ensure the tower crane’s stability.
Positioning Structural Steel for the Roof of the Mercedes-Benz Stadium
In 2014, the Atlanta Falcons broke ground on a $1.4 billion new stadium in downtown Atlanta. Set to complete in 2017, the 30-story structure will contain roughly 20,000 tons of structural steel, a retractable roof and a 360-degree halo video board that will span five stories inside the stadium.
