BEFANBY Low voltage electricity operated die transfer flat heavy load cart rail guided cart, the power source AC380v is transformed into AC36v two-phase and are respectively connected to the two rails.Then the flat carts' wheels conduct the AC36v on rail into the electrical appliance box at the bottom of the carts, And then the AC36v is transformed into DC36v and then control the DC motor through the DC control system to make the flat carts start, stop, go forward and backward railways.
