STRAND JACKS USED TO LIFT A STADIUM ROOF STRUCTURE

Fagioli operates a range of jacks from 15 to 750 tonnes capacity each based upon lift cables of 1 to 50 strands of 18mm diameter, 7 wire die-compacted, prestressing strand of guaranteed minimum breaking load of 38 tonnes per strand. Jacks may be used singularly, in pairs, or in groups to give any lifting capacity required.

POWER PACKS...
Power packs provide the oil to the jacks and can be powered by diesel engine or electric motor.

All power packs have direct, panel mounted, monitoring and control systems
Maximum pumping pressure, hence jack lifting force, can be pre-set or altered at
will by pressure control valves on the panel
Further electronic monitoring can display number of lift strokes completed and
individual stoke positions at each jack.

Similar control and monitoring facilities can also be positioned remote from the power pack to fully computerised systems, including automatic lifting and lowering capabilities
Fagioli are able to select power pack and jack combinations to meet all functional requirements of synchronised lifting by multiple jacks at appropriate lifting speeds.

MONITORING AND CONTROL SYSTEMS...
All Fagioli power packs have direct, panel mounted, monitoring and control systems.
It would be typical that a Fagioli operator might control a multi-jack lift or lower by means of two functional control levers on the power pack with the option of opening or closing hydraulic flow to all or any jacks by means of line valves.

Maximum pumping pressure, hence jack lifting force, can be pre-set or altered at will by pressure control valves on the panel.
Further electronic monitoring can display number of lift strokes completed and individual stroke positions at each jack.

Similar control and monitoring facilities can also be positioned remote from the power pack to fully computerised systems, including automatic lifting and lowering capabilities

The Advantages of Fagioli Strand Jacks and Control Systems
- Comprehensive, completely automatic, remote control and monitoring where required;
- Mechanically fail-safe gripping mechanisms;
- Pre-set overload protection;
- Automatic synchronisation of lifting speeds irrespective of loads;
- Ample operating speeds;
- Load is held mechanically not hydraulically at any time movement is stopped;
- Movement can be stopped and held indefinitely at any point in jack stroke;
- Extremely precise adjustment of the lift for setting of weld gaps or the fitting of steelwork connecting bolts;
- Automatic lifting and lowering without any personnel in attendance at the jacks;
- Easy re-distribution of the jack loads;
- Minimal re-lubrication of gripping mechanisms - lifts of 90 metres and horizontal moves of 250 metres have been completed without the need for re-lubrication;
- Gripping mechanisms are fully accessible at all times;
- Full efficiency in all attributes from vertical through to horizontal;
- Completely self contained and very rugged.
