The OmniCrane™ Equipment Assembly forms a self-contained system capable of lifting and positioning all the components that make up the wind turbine generator including tower sections, nacelle, hub and blades.
Design
The simple design is based on modular techniques used in tower crane technology.

Chain Jack Lifting Hoist
The Chain Jack lifting hoist is adapted from field-proven offshore oil and gas applications. This equipment is designed for marine environments and has the capacity to lift the largest offshore wind turbine generators.
Chain is used instead of wire ropes to provide a robust and simple corrosion resistant lifting element.
Every day is a good day when you’re designing the world’s biggest chain jacks.
OmniCrane
The OmniCrane can be skidded on rails while under load to position the load as needed to mate to the floating hull foundation.
The OmniCrane consists of four lattice beam legs and bridging elements at the top that are built from modular sections as high as necessary to meet the project requirements. These legs can be skidded in the horizontal “x” direction along beams set into the concrete of the quay. The lifting hoist is a chain jack with 1500Te capacity that is mounted on a set of beams allowing the chain jack to traverse in the “y” direction. The chain jack provides lift and lower capacity in the “z” vertical direction. A chain locker is used to store excess chain and provide counterweight to balance the load of the chain jack as it lifts.
OmniLift™
When coupled with an OmniLift™, the system provides a stable platform for tower and nacelle integration which will massively reduce risk for the project in terms of safety and schedule.
