Applications
Enerpac has gained unique expertise in delivering hydraulic solutions for the controlled movement and positioning of structures.
Replacing the Elvira Railroad Bridge Span with a Jack-up System
The Elvira Railroad Bridge, built in 1906, spanned across the Cahaba River in Helena, Alabama. The old double-track open deck superstructure had reached the end of its useful life and was scheduled for replacement with a new single-track ballasted deck superstructure. Burkhalter, lifting, rigging and transport professionals, was selected to execute the replacement of Span 2 over the river.

SKYFFOLDING Scaffolding and Lifting System Supported by Strand Jacks
Heavy lift specialist, Enerpac Heavy Lifting Technology, has supplied Korean based engineering company, KLES, with strand jacks for an innovative tower scaffolding system called SKYFFOLDING™ (Platform-supported Boiler in-Furnace Scaffolding and Lifting System). The Enerpac HSL1507 strand jacks support and lift the pendant-type, scaffolding system, as it grows, providing a safer working environment than traditional scaffolding during power plant boiler furnace maintenance.

Jacking & Skidding a Tunnel Boring Machine for the Next Drilling Phase
In 2013, Jakarta, the capital city of Indonesia, broke ground on a mass rapid transit (MRT) system in hope to alleviate the city’s traffic congestion. The rail-based MRT is expected to stretch across over 108 kilometers. A tunnel boring machine (TBM) is being used to construct the underground routes. One of the critical phases of the tunnel construction is the pass through, in which the TBM needs to be moved through the underground stations to be relocated to the next drilling position.
Infrastructure
Controlled Tightening on Dump Truck Suspension Struts
The maintenance team needed to replace the suspension strut bolts on 777F, 785D, 789D and 793F dump trucks. Due to the confined location of the suspension struts there was limited space for accessing the bolts. Existing methods of using flogging spanners often took several hours to replace the nuts, caused minor injuries to hands and the torque was not accurate.
Mining
Slew Bearing Replacement on a Ship Loader
Replacing the slew bearing on the 40 year old (grain) ship loader required lifting the upper structure 300 mm to provide adequate clearance during replacement. Keeping the boom connected made it challenging to maintain the balance of the ship loader during the lift. Maintaining the center of gravity of the ship loader throughout the lift was critical.
Infrastructure
Offshore Highway Construction - Lifting Challenges
The offshore highway is of a multi span bridge structure located in the open sea 100m to 200m from the shoreline. Each bridge pier consists of various concrete components, one of which will be a reinforced concrete, gravity base, which is placed on the seabed.
Infrastructure
Placing Bridge Girders with Precise Control with a SyncHoist System
The Pacific Highway expansion project includes hundreds of kilometers of new highway between Sydney and Brisbane. Part of the project includes the construction of a new bridge over the Nambucca River. When completed the Nambucca River Bridge will be 850 meters long and will include 21 bridge spans comprised of four precast concrete girders. Weighing up to 158 tonnes and 41 meters length, each of the girders will need to be placed on bearings with precise control.
Bridges
Safe Disposal of Old Gas Cylinders with Hydraulic Punch Set
Before gas cylinders can be disposed of in Australia, they must be completely unusable, to stop people reusing faulty and dangerous cylinders and causing themselves serious harm. The most effective way to do this is to puncture a hole in the cylinder.
Manufacturing
Electric Rope Shovel Undecking
Routine maintenance is required on a P&H 4100XPC Electric Rope Shovel after every 30,000 hours of operation. The maintenance activities require the upper section to be lifted off the car body to machine bearing surfaces and inspect and repair structural components. Weighing approximately 1,000 tons, lifting the upper car body requires a significant amount of force and control.
Mining
Power Plant Heaters Installed with a Telescopic Hydraulic Gantry
Leading North African international logistics company, Marine Maroc, has used its new Enerpac SL400 gantry to install high pressure heaters weighing 130 tons at the 2×693 MW Safi coal-fired power plant located close to the city of Safi in Southwest Morocco.
Power Generation
Turbine and Generator Installation at a New Power Plant in Libya
Çalık Enerji is constructing a new simple-cycle power plant with a 542 megawatt capacity in Khoms, Libya. The Sarilar Group was tasked with installing a GE gas turbine weighing approximately 280 tons and a GE generator weighing approximately 214 tons. Installation required lifting the turbine and generator over 5 meters high and lowering into position on a concrete foundation.

Positioning Structural Steel for the Roof of the Mercedes-Benz Stadium
In 2014, the Atlanta Falcons broke ground on a $1.4 billion new stadium in downtown Atlanta. Set to complete in 2017, the 30-story structure will contain roughly 20,000 tons of structural steel, a retractable roof and a 360-degree halo video board that will span five stories inside the stadium.
