▼ Pre-cast segmental bridge building<br />

To support the 80 tons main cast section of a<br />

segmental bridge, Enerpac CLL-506 (50 tons)<br />

jacks offer beside the required lifting <strong>for</strong>ce the<br />

positive locking feature c<strong>all</strong>ed ‘mechanical<br />

lock-nut’. On each pier of this elevated light<br />

train system 4 CLL-506 jacks support and<br />

align the cast sections. Once the hanging cast<br />

sections are aligned with the main cast<br />

sections, the jacks are mechanic<strong>all</strong>y locked to<br />

<strong>all</strong>ow permanent fixation of this fly-over. Jobs<br />

like these are made significantly easier and<br />

faster using high pressure hydraulic jacks,<br />

instead of temporary supports or mechanical<br />

screw jacks.<br />

Products:<br />

• CLL-Series, lock-nut jacks<br />

▼ Lowering bridge sections<br />

For the lifting and final positioning of bridge<br />

sections in the Alps, Enerpac CLS-1006<br />

(100 tons, 6 inch/150 mm stroke) jacks were<br />

used. The jacks were powered by several<br />

ZE4320MW electric pumps.<br />

Products:<br />

• CLS-Series, single-acting high tonnage jacks<br />

• ZE-Series, electric pumps<br />

Enerpac in action<br />

▼ World-beating heavyweight lifting with pinpoint precision<br />

An Enerpac synchronous hydraulic lifting<br />

system has been employed in Queensland<br />

(Australia) to lift, within tolerances of 0,5 mm,<br />

a huge mining dragline weighing more than<br />

3500 tons.<br />

The PLC-controlled precision hydraulic<br />

system with eighty 100-ton hydraulic<br />

cylinders was used to lift the dragline <strong>for</strong><br />

essential maintenance of the bearing surfaces<br />

on which the dragline swivels. It also<br />

delicately tilted the huge suspended weight to<br />

simulate different loads on the structure so<br />

bearing surfaces could be precisely machined<br />

to accommodate them and maximise the<br />

bearing surfaces’ lifespan.<br />

Synchronous safety on huge walking dragline<br />

reveals efficiency and control benefits <strong>for</strong><br />

many industries.<br />

Products:<br />

• RR-Series, double-acting jacks<br />

• SLS-Series, Synchronous lifting systems<br />

• Electric split-flow pumps<br />

• PLC-Control units<br />
