▼ 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 />
