Liftra Designs ‘Climbing Crane’ for Wind Turbine Installation 5X faster Using Ansys Cloud and Ansys Mechanical

Liftra has revolutionized the installation of wind turbines by creating the LT1500 crane that “climbs” the wind turbine tower as it is being assembled instead of sitting beside it. The bottom of the crane grabs onto a flange of one tower section and lifts the next section into place.

Then, a “hoist block” travels up and attaches to the higher section and pulls the crane up the tower to attach to the higher flange. In a sequence of such grabbing and hoisting moves, an entire wind turbine, including the tower, nacelle, rotor, and blades, can be constructed
