Enerpac New Jack-Up Systems

Enerpac New Jack-Up Systems
Enerpac Jack-Up Systems provide a new solution for lifting, lowering, and holding heavy loads. The multi-point hydraulic lifting system uses an incremental stage-lifting principle. The lifting frame of each jack-up unit contains four hydraulic cylinders—one in each corner—which synchronously lift and stack steel barrels, forming lifting towers.

A typical system setup includes four jack-up towers positioned under each corner of a load. A four-unit setup has a lifting capacity of 2,000 metric tons (500 tons per unit). A load is lifted in increments as boxes are slid into the system, lifted, and stacked to form ‘lifting towers’. The system is operated and controlled by a computer control unit, and each unit’s lifting and lowering operations occur simultaneously. The synchronous technology of the control unit maintains the load balance. The hydraulic power units are embedded within each lifting frame. Safe lifting heights depend on the expected side load. The system can position a load with pinpoint accuracy and mechanically hold it from below. Enerpac Jack-Up Systems are easy to operate, safe, and economically transported.

A Jack-Up System is comprised of 3 main components:
1. Multiple jack-up units
The most common system setup includes 4 jack-up units.

2. Computer control unit
A touch screen control for operating the jack-up system with automatic and manual lifting settings.

3. Electronically controlled diesel power unit
Supplies hydraulic power to the system.

The JS500 is powered by an external powerpack.

The EP5000 powerpack is embedded within each unit’s lifting frame.

A Jack-Up Unit is comprised of 6 main components:
Base frame

Supports the lifting frame. Skid track attachments are optional.

Skid tracks (optional)

Enable the jack-up system to be skidded in two directions.

Lifting frame

Contains hydraulic cylinders located in each corner to lift the boxes and locking strips for stable stacking.

Steel Boxes (barrel)

Boxes are slid into the lifting frame and are lifted by the cylinders. Each box is designed to carry 500 metric tons.

End box (barrel)

The top box where the load is placed.

Box insert rollers

Rollers facilitate easy entry of boxes into the lifting frame.

Key Features:
Self-contained hydraulics in each jack-up unit for an uncluttered work area

Synchronize lifting with multiple jack-up units (typically 4, expandable)

Lifting barrels stack together to mechanically hold the load

Up to 5% side load capacity depending on lifting height

Computer-controlled operation with automatic lifting settings
