H-type coupler with different shank mechanically joins separate nearby vehicles together to form a train. It also provides energy absorption during connection and services. In addition to this, our offered product is made to slide into the Coach's draught gear pocket and absorb dynamic energy in both draw and buff modes. H-type coupler with different shank offers a way to mechanically join separate nearby vehicles to form a train. It can be found at each vehicle's ends. The truck may travel independently to account for track curvature and elevation variation while keeping connected together when coupled with a coupler from a nearby car.
