Wind Turbine Coupling Test Stand
Emprise offers a complete, turn-key test stand for static load testing of large wind turbine drive shafts, couplings, overrunning clutches and torque limiters. The system performs bi-directional static load, life cycle fatigue and proof load testing without the need for a high-power drive and absorption system. The test article is loaded with a hydraulic rack-and-pinion oscillator. The load is resolved to ground through a static torque sensor. Built on a t-slotted base the design provides good flexibility for variety of test setups.
The modular design allows Emprise to customize the system to your specific testing needs.
