When President Biden signed the $1.2 trillion infrastructure bill into law last month, he destined an already booming construction industry to reach new heights. Before the bill was passed, ResearchandMarkets.com projected the construction industry in the United States would grow by 15.6% this year. With the US government’s hefty investment in civil construction, the construction industry will grow significantly in 2022 and beyond.  Demand for heavy lifting and specialized transport equipment is expected to skyrocket.  “As the first heavy lifting company in the United States to offer a jack-up system rental with 2,000 mton capacity, Engineered Rigging will meet the most demanding heavy lifting needs of our clients,” shared Kitchen.

Engineered Rigging Co-founders Christopher Cox and Eddy Kitchen have carefully followed these developments and acted proactively by expanding Engineered Rigging’s fleet of heavy lifting equipment. In the June issue of Heavy Lifting News, we announced the addition of our rental fleet to include two Enerpac Super Lift SL60 hydraulic gantries and four sling adjusters (SyncHoists) with a 370-mton capacity each. Today, we’re thrilled to announce that we have ordered an Enerpac JS-500 jack-up system and are accepting rental reservations for 2022. Engineered Rigging is the first company to have this model available for rental with technical support in the United States. It has a variety of civil construction applications, including bridge building and demolition, subway construction and renovations, and port construction.

How Does a Jack-Up System Work? 

Enerpac JS-Series of jack-up systems features a custom-developed, synchronous heavy lifting system. A typically setup includes four jack-up units, one positioned under each corner of a load. A load is lifted as barrels are slid into the system, lifted and stacked, to form “lifting towers.” The lifting towers incrementally lift the load and mechanically hold it into place at the desired height. The lifting and lowering functionality of Enerpac’s jack-up systems are managed via a hand-held computer control unit that optimizes control and safety.
