Why APPI:
Raising and lowering a wind turbine for maintenance presents a challenge under any circumstance, but when the wind turbine is remotely located in the foothills of California, a lack of power compounds these challenges even further. This was the situation facing Cal Poly State University when they needed to upgrade their hoist system for maintaining a wind turbine in a remote area with limited access to power.
Recognizing the complexities of their application, Cal Poly reached out to Allied Power Products, Inc. (APPI) for assistance in developing a solution tailored to their specific needs. Through collaborative discussions, Cal Poly and APPI determined that the Columbia HG5600-2A17-L-02 AC electric hoist, powered by a truck-mounted generator, would provide the required line pull, duty cycle, and brake capacity for safely and efficiently raising and lowering the wind turbine.
To ensure optimal performance and longevity in the harsh outdoor environment, APPI customized the hoist with several key features:
- A nickel-plated drum and tension plate to resist corrosion from exposure to the elements
- Stainless steel fasteners throughout for enhanced durability
- 150′ of 3/8″ diameter synthetic rope for precise positioning of the wind turbine tower
The resulting hoist system, not only met but exceeded all of the university’s requirements. It is expected to provide years of reliable, low-maintenance service in the challenging conditions of the remote California foothills, allowing Cal Poly to more easily maintain their wind turbine and continue their renewable energy research.
