LT1000 Liftra Self-Hoisting Crane

Craneless Replacement of Major Components

The Self-Hoisting Crane eliminates the need for large mobile cranes when changing major components. The crane climbs from its container to the nacelle, suspended and guided by its own wires. Atop the turbine, the crane turns 180 degrees and installs on its base inside the nacelle, ready for operation.

The Self-Hoisting Crane itself comes in a single 40 ft container. The crane base comes in a separate 12 ft container.

We continue to develop crane bases for more turbine models. Current turbines include:

• Acciona AW3000
• Gamesa 2 MW platform (G8x, G9x)
• GE 1.5 platform
  • GE 1.5 – 70.5, 77, 82.5, 87
  • GE 1.6 – 77, 82.5, 87
  • GE 1.68 – 82.5
  • GE 1.85 – 82.5, 87
• 1.6 MW platform
  • GE 1.6 – 100, 103
  • GE 1.7 – 100, 103
  • GE 1.79 – 100
• GE 2.x platform (F1 F2-US)
• Mitsubishi MWT1000a
• Nordex 2.5 MW Gamma
• Nordex Delta4000
• Siemens 2.3 MW
• Siemens 2.625 MW G2-Mk4
• Suzlon S88
• Vestas 2 MW platform (V66 (1.75 MW) V80, V90, V100, V110, V116, V120)
• Vestas/NEG Micon V82, NM82, NM72
