Abstract
The invention discloses a braking method for a tractor and a device thereof. The method is characterized in that the braking control is performed on a braking disc in a one-to-many mode through an iron core assembly and over two armatures capable of moving independently. Because multiple independent moving armatures are used in one iron core assembly, other armatures still can obtain enough braking force to brake the elevator tractor when one of the armatures fails, and the problems of large space occupied by using two circular plate armatures, high cost and difficult installation are solved.
