Ship sections, modules, turbines, presses, bridge spans, vessels being set on foundations. Through Enerpac Heavy Lifting Technology we supply gantries, strand jacks, jack-up systems, synchronous lifting and skidding — available for rent or purchase, specified against your load, your headroom and your floor.
Heavy lifting is a method question before it is an equipment question. Headroom, floor loading, travel distance, how precisely the load has to land, and whether it has to be held mechanically while people work under it — those decide the answer. Here is the range.
| System | Capacity | What it's for |
|---|---|---|
| Telescopic hydraulic gantries ML, SL, SBL-SERIES | 45 – 1,178 tons | Precision lift and position of heavy loads where there is no overhead crane, or the crane can't reach. Sets up in the bay, on a barge deck, or in a plant with a low roof. |
| Heavy lifting strand jacks HSL-SERIES | 17 – 935 tons | High-capacity lifting with precision control over long strokes — roof lifts, superlifts, module hoisting, bridge segment raising. |
| Jack-up systems JS-SERIES | 275 – 550 tons | Synchronised incremental lifting with a mechanical hold at every stage — for loads that must be raised in stages and parked safely. |
| Self-locking cube jacks SCJ-SERIES | 56 – 110 tons | Incremental lifting with automated mechanical locking. Low headroom, no cribbing crew. |
| Synchronous lifting systems EVO / SFP SPLIT-FLOW | Multi-point | Many cylinders, one controlled motion — keeping a long or unevenly loaded structure level while it moves. |
| Synchronous hoisting — SyncHoist SHC, SHP-SERIES | 60 – 120 tons | Precision positioning jacks under the hook, so a crane can set a load to the millimetre instead of the inch. |
| Low-height skidding systems LH-SERIES | 400 tons | Jack-and-slide moves in confined spaces — getting a module across a bay when there is no room for a transporter. |
| Hydraulic turntables ETT-SERIES | 225 – 450 tons | Controlled rotation of a heavy load in place. |
| Electric trolley systems ETR-SERIES | 50 – 100 tons | Synchronised travel at 82 – 164 ft/hr for controlled horizontal moves. |
| Battery-powered machine skates EMLS, EMV-SERIES | 11 / 33 / 55 tons | Machine moving and millwright work at 26 ft/min — no air line, no tow motor, no crew pushing. |
Capacities are per system as published by Enerpac; the working configuration depends on load geometry, ground conditions and rigging. We size it with you before anything is quoted.
Hull section and module lifts, engine and gearbox setting, moving assemblies across a bay with no crane coverage, and setting equipment on a barge deck where a mobile crane can't be positioned.
Exchanger bundle handling, vessel and column setting, jacking equipment off foundations without a crane pick in a congested unit.
Incremental bridge lifting and launching, bearing replacement, seismic retrofit jacking, and synchronised superlift on spans and segments.
Presses, mills, generators and production lines moved and set to tolerance inside an operating building.
Multi-point jacking for pile and foundation testing where every point has to be controlled and recorded.
Loading, unloading and positioning oversize pieces — girders, vessels, transformers — at the point where the trailer stops and the load still has to move.
Weight, dimensions, centre of gravity, pick points, headroom, floor or deck capacity, travel distance and how precisely it has to land.
Gantry, strand jack, jack-up, skidding or synchronous lifting — and often a combination. This is where the money is saved or lost.
Both are available. A one-off lift usually rents; a yard that does this monthly is usually better off owning. We'll tell you which one you are.
Application engineering, setup, operator familiarisation, and Enerpac's inspection and maintenance program for equipment already in service.
Already own heavy lifting equipment? Enerpac's inspection and maintenance program covers on-site inspection of gantries, strand jacks and jacking systems — worth doing before the lift, not after the incident.
Heavy lifting is one chapter of a 400-page catalog. We supply the rest of it too — the workhorse hydraulics that end up on every job.
Single and double-acting, aluminium and steel, lock-nut, low-height, hollow plunger, pancake and cylinder-pump sets.
Hand, air, electric and battery pumps to 10,000 psi, directional control valves, split-flow pumps and manifolds.
Shop and workholding presses, hydraulic and mechanical pullers, and the specialty tools that solve one problem well.
Hydraulic and electric wire and cable cutters, cutter/spreader combination tools, and hydraulic nut splitters for fasteners that are past removal.
Flange facing machines and portable machining for surfaces that have to be trued in place instead of shipped out.
High-pressure hose, couplers, gauges, digital gauges, fittings and hydraulic oil — the parts that fail first and stop everything.
A second full high-pressure line — cylinders, pumps, jacks, shop presses, pullers and hydraulic and mechanical tools, with lifting and positioning equipment for construction, mining and shipbuilding.
On bolting: hydraulic torque and tensioning stays with our core lines — TorcUP for hydraulic torque and TensionPro for tensioning. See Lines We Carry.
Weight, dimensions, headroom, where it starts and where it has to end up. We'll come back with a method, an equipment list, and a rent-or-buy number.
