Besides its complete line of high quality high pressure hydraulic cylinders, Enerpac is also well known for its complete line of high quality high pressure jacking systems designed for portability and tight fits as part of its integrated high pressure lifting systems. Enerpac high pressure jacking systems operate by grabbing and lifting or lowering cables or strands passing through their hollow centres.
Strand Jacking System
High pressure jacking systems are used for moving, positioning or lifting of heavy structures in industrial processes. The most innovative of these systems so far is Enerpac’s Strand Jacking system, which lifting technique originates from the concrete post tensioning principle and which forever changed the way we deal in the movement and positioning of heavy structures.
Enerpac’s strand Jacking System or simple strand jack uses a bundle of steel cables or strands guided through a hydraulic cylinder; above and below the cylinder are anchor systems with wedges that grip the strand bundle. By stroking the cylinder in and out while the grips are engaged in the anchors, a lifting or lowering movement is achieved.
Advantages Of Enerpac Jacking Systems
Safety is a primary focus in every Enerpac product and operation. All systems are certified and tested under Lloyd’s witness. Each installation is delivered with an instruction and operation manual in English.
Higher capacity. Enerpac strand jack systems are available from 30 up to 1.000 tonne capacity. The number and type of strands used in a jack determine the safe working load of a jack.
Ease of use. Enerpac heavy lifting solutions, just like the rest of its line of industrial solutions, were all designed to make operations more productive and this is achieved with making the solutions easier to use by using the latest and most advanced force-generating technologies.
Maintenance and repair services. Enerpac has an extensive network of distributors and service centres all over the world to provide top quality maintenance and repair services for Enerpac products.
Industrial Applications of Strand Jacking System
Thousands of industrial projects that required lifting, positioning, and movement of heavy load materials have been possible and accomplished faster and safer with the use of the strand jacking system by Enerpac. Some of the most notable of these projects include-
The lifting of the London Eye in London United Kingdom. For this project, HSL-Series strand jacks powered an innovative mega to successfully lift the London Eye, a cantilevered observation wheel with a height of 135 meters, the world’s tallest wheel.
The lifting of 2,000 ton steel roof sections at Abu Dhabi Airport hangar. For this project, HSL-Series strand jacks were used to lift 3 gigantic steel roofs weighing 2,000 ton each. The roofs were constructed at ground level and were lifted 40 Ms creating aircraft maintenance hangers big enough and high enough to house the new Airbus A380 planes of the airport.
Lifting and installing the Deck sections of the Golden Horn Metro Bridge, a cable-stayed bridge that connects the Beyoğlu and Fatih districts on the European side of Istanbul. To build the bridge, 300 ton deck sections were needed to be lifted off the barge nearly 17 meters and installed into position.
