Lifting and Rotating Suspended Loads with a Strand Jack Gantry with Rotation Unit


Power Generation Plant




One of the many challenges for logistics companies in the power generation sector is installation of new equipment. 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.


Enerpac has developed a 450 ton, lift and rotation strand jack gantry - the first of its kind to feature a rotating unit - enabling lift and rotation of large turbine equipment during power plant installation and maintenance.

The Enerpac strand jack gantry comprises four modular legs supporting an overhead skid track for an Enerpac SBL1100 gantry. A pair of 200 ton strand jacks is 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°, a unique feature for a gantry. The strand jack gantry and rotation unit are controlled via an Intellilift wireless control system.

The 450 ton, lift and rotation gantry is designed such that the entire gantry can be transported in multiple standard containers for ease of deployment at port logistics centers and power plants. It was developed and manufactured at Enerpac’s Integrated Solutions facility in Hengelo in The Netherlands.
