Product catalog summary
Overview: The document provides detailed information on the Enerpac JS-Series Jack-Up Systems, which are specialized multi-point lifting systems designed for heavy lifting applications. These systems are used in various industries for tasks such as bridge maintenance, lifting heavy equipment, and de-propping structures.
Specifications: The JS-Series includes models with capacities ranging from 125 to 750 tons per lifting tower, with lifting heights between 6 to 20 meters. Each jack-up unit is equipped with self-contained hydraulics, allowing for a clutter-free work area. The system can handle up to 5% side load capacity depending on the lifting height.
System Components: A typical setup includes four jack-up units, each with four hydraulic lifting cylinders. The system uses stacked steel barrels to form lifting towers, and operations are controlled by a computer control unit for synchronous lifting and lowering.
Computer Controls: The Enerpac Jack-Up Systems feature computer controls that provide precision and safety. The system includes automatic synchronization, overload and stroke alarms, and an emergency stop switch. The Smart Box SBJS-V4 allows control of up to 8 towers simultaneously from a central location.
Accessories and Customization: Enerpac offers various accessories and custom configurations, including base frame trolley systems, bracing kits, adjustable top barrels, and automatic barrel loading systems. Custom versions can be designed to meet specific application needs.
Applications: The systems are suitable for bridge construction and decommissioning, lifting and lowering heavy equipment, and leveling heavy structures. They are also used for load transfer from temporary steelwork.
Safety and Reliability: Enerpac emphasizes safety and reliability, with features such as synchronous lift/lower control, load monitoring, and emergency stop capabilities. The systems are designed to ensure stable and safe lifting operations.

Enerpac Jack-Up Systems Enerpac Jack Up Systems The jack up system is a specialized multi-point lifting system. A typical system setup includes four jack up units positioned under each corner of a load. A load is lifted in increments as barrels are slid into the system, lifted, and stacked; forming ‘lifting towers’. A jack up system is operated and controlled by a computer control unit. Example: A four unit setup with JS250 has a lifting capacity of 1000 ton (250 ton per unit). The lifting frame of a jack up unit contains four hydraulic lifting cylinders, one in each corner, which lift the load...
