Typical layout for a 4 points synchronous lifting system.

ControlledHydraulic Movement

Typical Synchronous LiftingApplications ?Bridge lifting and repositioning?Bridge launching?Lifting and lowering of heavyequipment?Leveling of existing structures andbuildings?Structural testing ?Lifting and weighing of oil platforms?Tunnel jacking and pushing. See www.enerpac.com and pages228-229 or more application information.

?4 to 64 points, load and stroke monitored and controlled?Capacities from 10 up to 1000 ton per lifting point ?Up to 1 mm accuracy over full plunger stroke ?PLC-control unit with user-friendly touch screen ?Automatic data storage and read-out for reporting andgraphical representation?System secured with warning and stop features toachieve optimal safety.

Heavy Lifting Cylinders For a complete line ofdouble-acting cylinders seethe Enerpac CylinderOverview in the E325e catalogue.

System Options:?Load and force measurement ?Load cells for precise force measurement up to 0,1%of full scale?Digital stroke sensors for: -up to 0,1 mm accuracy over full stroke -up to max. 1 km distance between control unit and lifting points?Two-axis tilting control to level structures ?Oil heater or heat exchanger for extreme conditions.

One of the world’s first and largest lifting jobsfor maintenance of a 3500 ton mining dragline was successfully done with an Enerpac synchronous hydraulic system: exact aligning of bearings on the rail on which this dragline rotates.
