Enerpac has developed a 450t lift and rotation strand jack gantry, featuring a rotating unit.

The company said the gantry enables lift and rotation of large turbine equipment during power plant installation.

“The main challenge for logistics companies in the power generation sector is installation of new equipment,” said Enerpac. “Loads are typically transported on trailers positioned parallel to the power plant, however the equipment needs to be lifted and installed perpendicular to the trailer.”

The new strand jack gantry provides a lift and rotation capability for loads up to 450t to a height of 15m.

It comprises four modular support legs supporting an overhead skid track for an Enerpac SBL1100 gantry. A pair of 200t strand jacks are positioned on each gantry beam. The strand jacks are, in turn, connected by steel strands to a centrally suspended, custom-made rotation unit and lifting beam.

The lifting beam allows the load to be rotated by 90°. The strand jack gantry and rotation unit are controlled via an Intellilift wireless control system.

“The strand jack gantry design combines the strength of strand jack lifting with the flexibility of a hydraulic gantry, and an innovative load rotation capability, to provide a highly capable lifting system for heavy loads,” said Jeroen Naalden, director at Enerpac Integrated Solutions.

The entire gantry can be transported in multiple standard containers for ease of deployment at port logistics centres and power plants. It was developed and manufactured at Enerpac’s Integrated Solutions facility in Hengelo, The Netherlands.
