Using the HMLS cord which has high strength, high elasticity and low shrink as the framework materials.

Using the classical V-Belt which are made of high strength, aging resistance and flexing resistance of chloroprene rubber and cotton canvas, 

Connect multiple classical V-Belts through articulamentum, and the foundation as a unit, which solve the problems of single V-Belt that lead to vibrate,

Clap and flip the belt during the operation. And it makes each V-Belt bear averaged force during the operation and increase the load-bearing ability and service life.
