HEAVY LIFTING Ӏ SECTOR ROUNDUP
hold the load. Several attributes distinguish the JS250 from other alternative lifting equipment. It is a computer-controlled system with single operator control optimising lifting safety and repeatability. It has self-contained hydraulics in each jack-up unit designed for optimal control and an uncluttered worksite. The JS250 has an adjustable locking top barrel that minimises setup time by allowing precise system height adjustment. It also has a compact footprint that enables lifting in limited space. Its incremental lifting functionality allows mechanical lockout at 19.7 inches (500mm) intervals during the lifting cycle, while the maximum controlled lifting speed is 13 ft. (4m) per hour. A typical setup for a jack-up
system includes four units – one positioned under each corner of a load. Barrels are slid into the system to form ‘lifting towers’ and automated computer controls are used to elevate the load to the desired height. The load can be held in place mechanically by the jack-up system or lowered as required by removing barrels.
Both Engineered Rigging and Marraffa have invested in an Enerpac JS-250 Jack-Up System
According to Engineered Rigging
the power, compact footprint, and ease of use of the JS250 makes it an ideal solution for projects of all sizes and complexities including bridge construction and maintenance, modular construction, industrial maintenance, machinery moves, the lifting lowering and levelling of heavy structures and buildings, and load transfers from temporary steel works. “Engineered Rigging continually
invests in cutting-edge technology to provide our clients with the most effective and reliable solutions on the market, enabling their teams to self-perform heavy lifting operations,” says Mike Beres, vice president of Engineered Rigging. Italian heavy lift specialist,
The Liebherr
LS 250 is designed for heavy-duty handling
Marraffa has also invested in an Enerpac JS-250 jack-up system which it plans to use for bridge launching projects. It is the company’s first Enerpac heavy lift system. Marraffa provides heavy lift, specialised transport and industrial handling services both nationally and internationally.
“The Enerpac Jack-up system is
an important addition to our heavy lift fleet and in keeping with our commitment to providing creative and cost-effective solutions,” says Pasquale Marraffa, head of purchasing at Marraffa. “It gives us the flexibility to take on projects in space restricted construction sites, as well as the stability to lift loads up to 1000 tonnes even during windy conditions where we couldn’t use a crane.” Hamburg, Germany-based global shipping company Dship Carriers is expanding its fleet with eight LS 250 heavy-lift ship cranes from manufacturer Liebherr for installation on four of its newest vessels. According to Liebherr, the design and low deadweight of the cranes means they can be easily integrated on any type of ship. The LS 250 cranes have a lifting
capacity of up to 250 tonnes and a maximum outreach of 36 metres. The cranes’ hydraulics are housed in pipes and its crane column is fully enclosed; this is designed to protect the components inside the crane in harsh environments, reducing downtime and maintenance costs due to premature ageing of components. The eight cranes are currently being manufactured at Liebherr’s Rostock site. In 2026 they will be
