Methodology

The compact and containerized up-tower cranes loaded for transport in just one ISO container.

A significantly smaller construction area is required, with fewer crews and heavy vehicles. This means a faster repair schedule, less disruption to local terrain and wildlife, plus greater overall workplace safety.

Up-tower cranes are mounted in the nacelle using a wind turbine brand a/o type specific interface. This interface will be bolted to the nacelle to create a stable and safe platform for the up-tower crane.

Once the interface is mounted the electrically powered 3mT Heli-Hook™ up-tower crane is hoisted by the service crane into the wind turbine to perform small major component exchanges or to function as assist crane for installation of the larger up-tower cranes.

With its hoisting capacity of 3mT the Heli-Hook™ up-tower crane is here used as assist crane to hoist the larger up-tower crane in parts into the wind turbine for installation on the nacelle mounted interface.

Depending on the nature of maintenance operation, different crane types and capacities may be deployed. Every up-tower crane type is capable of hoisting the next category up for installation.

Up-tower cranes are structurally bolted to the turbine for safe and stable operations, eliminating ground stability issues.

KenzFigee’s compact and lightweight up-tower cranes are assembled quickly on-site to expedite project completion by up to two-days. Standard cranes often require an entire day for set-up before work can start.

Maximized stability specifically engineered to increase ease and precision of wind turbine maintenance. This extra stability allows safe work to continue in wind speeds up to about 40 miles per hour (18 meters per second), keeping workers safe while projects are kept on schedule and on budget
