The Shanjiang Derun maintenance crane can be installed on the top of nacelle of wind turbine generators (WTG for short) without changing the nacelle structure, and the crane can operate normally on existing wind turbines, easily installed to various wind turbine generators.

The maintenance crane adopts the modular design, which can be flexibly installed and dismantled, and can quickly replace large and medium-sized components. Compared to other large-scale maintenance equipment, it can effectively save at least 10 times maintenance costs. In complex on-site environments, it can be carried to the work site by operator, greatly improving installation and reducing installation costs. Compact design, large capacity, make wind turbine maintenance more efficient and cost-effective!
