Capacity Per Lifting Tower
125 – 750 ton
Lifting Height
Up to 6 – 20 metres

The jack-up system is a custom developed multipoint lifting system. A typical system setup includes four jack-up units positioned under each corner of a load. A four unit setup has a lifting capacity of 2,000 metric tons (500 tons per unit).

The lifting frame of a jack-up unit contains four hydraulic cylinders in each corner which lift and stack steel boxes. A load is lifted in increments as boxes are slid into the system, lifted, and stacked; forming ‘lifting towers’. A jack-up system is operated and controlled by a computer control unit. Each unit’s lifting and lowering operations occur simultaneously; the computer control unit’s synchronous technology maintains the balance of the load. The hydraulics power units are embedded within each unit’s lifting frame. Safe lifting heights are dependent on the expected side load.

Four models of the jack-up system are currently available:

• JS125
  • Lifting capacity per tower: 125 tons
  • Lifting height: 6 meters
  • Maximum side load: 3% at 6 meters
• JS250
  • Lifting capacity per tower: 250 tons
  • Lifting height: 10 meters
  • Maximum side load: 3% at 10 meters
• JS500
  • Lifting capacity per tower: 500 tons
  • Lifting height: 15 meters
  • Maximum side load: 4% at 15 meters
• JS750
  • Lifting capacity per tower: 750 tons
  • Lifting height: 20 meters
  • Maximum side load: 5% at 20 meters

A Jack-Up System is comprised of 3 main components
Multiple jack-up units
The most common system setup includes 4 jack-up units.
Computer control unit
A touch screen control for operating the jack-up system with automatic and manual lifting settings.
Electronic 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)
Enables the jack-up system to be skidded into 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 up by the cylinders. Each box is designed to carry a load of 500 metric tons.
End box (barrel)
The top box the load is placed upon
Box insert rollers
Rollers facilitate easy entry of boxes into the lifting frame.
