ENERPAC CUBE JACKS STREAMLINE FLIGHT SIMULATOR INSTALLATIONS
L
andry Simulation, a US firm that installs, updates and relocates flight training devices for airlines, aircrew training
centres and aircraft manufacturers, has purchased three Enerpac SCJ-50 Cube Jacks to help with the installation of the company’s flight simulators. The installation process involves setting the simulator, which weighs 35,000–50,000lbs (25 tons), onto a hydraulic actuator. “To set a simulator, Landry Simulation
historically used a system of chain falls, hydraulic cylinders, and a significant amount of wooden cribbing,” said John Kuka, director of business development for Engineered Rigging, which was asked by Landry Simulation founder Claude Landry to “improve the installation process” and to identify the safest, most efficient method for its operations using equipment that is easy to transport. After analysing the simulator installation process, Kuka recommended the SCJ-50 cube jack system. The portable cube jacks have a 56-ton lifting capacity per jack. The system utilises base lifting frames and self-aligning, lightweight steel cribbing blocks, instead of wooden cribbing materials. To simplify control of the lifting operation, all of the system controls are contained within the cube jack, aside from the main directional valve that is located on the hydraulic power unit. “An in-person demonstration helped Claude [Landry] gain an appreciation for the equipment’s compact design
and functionality,” said Kuka. “Seeing it in action, he realised that the cube jack system is a perfect fit for the safety and efficiency goals he wanted to achieve. “However,” Kuka added, “he had one
critical concern.” Typically, Engineered Rigging’s cube
jack systems – its fleet includes both the SCJ-50 and SCJ-100, which has a 110-ton lifting capacity – are powered by split- flow pumps, which require 480V/3 phase power. However, the build-out spaces for Landry Simulation’s flight simulators often have only standard 115V power. Working with Enerpac, Kuka identified an alternative power source: the ZE- Series hydraulic pump and a split-flow manifold, which the New York-based Landry Simulation also purchased. Landry Simulation first used the new
system for an installation at a flight training centre in Dallas and reported the new lifting system improved productivity and reduced the time to install the simulator. Kuka said: “The Engineered Rigging
team enjoys working with our customers to understand their needs and identify the best heavy lifting solutions. I was thrilled that we provided Landry Simulation with the technology to safely and efficiently install flight simulators around the world.” Meanwhile, Schares, a firm specialising in lifting and moving heavy loads, has completed the installation of a double- track railway bridge in Oldenburg, Germany, employing Enerpac SCJ-100 cube jacks, which raised and lowered the

bridge decks and parapet walls into their final position on the bridge bearings. Schares used the cube jacks and
a self-propelled modular transporter (SPMT) because the limited space would not allow the use of a mobile crane. In addition, this approach meant that the overhead power lines could remain untouched. Each 17.3m-long prefabricated bridge
deck, weighing 98t, was supported on the SPMT and brought to the construction site. Four SCJ-100 cube jacks were then used to gradually raise the bridge deck, and allow the removal of the SPMT and replacement with support jacks. The cube jacks were then placed on a support structure mounted on the SPMT and positioned under the deck. The bridge deck was raised up to 6.5m. By manoeuvring the SPMT, the deck was positioned horizontally, and reached its final resting position through the synchronised lowering of the jacks. “The Enerpac SCJ-100 cube jacks

were the right solution for this project,” says Christoph Schares, MD of Schares. “The load capacity, as well as the small footprint and installation height of the cube jacks with an up to 3m lifting height, made this project possible.” The Oldenburg-Wilhelmshaven railway line is being modernised to better connect the Wilhelmshaven container terminal to the national railway network. Enerpac has also launched the latest addition to its SBL-Super Boom Lift hydraulic gantry range – the SBL600 gantry. With a max lifting height of 10.6m, the three-stage telescopic hydraulic cylinder features a foldable boom, allowing transportation on standard flatbed trucks without the need for special permitting and routing. ●
