Engineered Rigging adds Enerpac JS250 jack-up system

The JS250 is well-suited to a variety of applications including bridge construction, modular building projects, industrial maintenance, machinery moves, structural leveling and load transfers.

Engineered Rigging has expanded its equipment offerings with the addition of an Enerpac JS250 Jack-Up System, a multi-point, fully automated lifting system capable of raising, lowering, and holding loads up to 1,100 tons. The Arkansas, USA-based company says the new equipment will enhance its ability to support a broader range of heavy lifting projects while maintaining a focus on safety and operational control.

“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,” said Mike Beres, vice president, Engineered Rigging. “Adding the Enerpac JS250 Jack-Up System to our fleet has expanded the scope of projects we can support.”

Each of the system’s jack-up units has a lifting capacity of 275 tons and can elevate loads from under 5 feet (1.475 meters) to nearly 33 feet (10 meters). The setup is typically used with four units placed under each corner of a load. As the system lifts incrementally, mechanical barrels are inserted to hold the load at fixed intervals.

The JS250 system includes several design features to improve jobsite efficiency including a computer-controlled interface allows a single operator to manage lifting operations, self-contained hydraulics within each unit reduce site clutter and improve control and an adjustable locking top barrel allows for fine height adjustments during setup.

The compact footprint makes the system suitable for space-constrained jobsites and mechanical lockout is achieved at 19.7-inch (500mm) increments during the lift. The system also allows for a controlled lifting speed of up to 13 feet (4 meters) per hour.
