4 Ton Hoist Overload Limiter

TW is my very reliable partner for building hoist, we have been working with each other since year 2015, and I am very happy with their performance and support. Very glad they have newly opened the most advanced production facilities in China, and hope I could be there for their official ceremony once the COVID is over.
