The invention provides a double brake device of an elevator and a double updating method of the brake device of the elevator, which do not need tedious brake force adjusting work and can simply double the brake device only by adding a small number of new components. The brake device of an elevator according to one embodiment of the present invention is provided with: a pair of brake arms (12a, 12b) that sandwich a brake drum (11) from the left and right and press brake shoes (13a, 13b) against the outer peripheral surface of the brake drum (11); a pair of extended brake arms (30A, 30B) respectively connected to the front ends of the brake arms (12a, 12b); a first brake arm operation unit (15A) that drives one of the brake arms (12a, 12b); and a second brake arm operation unit (15B) that drives the other brake arm between the extended brake arms (30A, 30B).

    一种电梯的双重化制动装置以及电梯的制动装置的双重化更新方法,不需要繁琐的制动力调整作业,仅通过追加少量的新部件就能够简单地使制动装置双重化。基于本发明的一个实施方式的电梯的制动装置具备:从左右夹持制动鼓(11)、并将制动靴(13a、13b)按压在制动鼓(11)的外周面的一对制动臂(12a、12b);在制动臂(12a、12b)的前端部分别接设的一对延长制动臂(30A、30B);对制动臂(12a、12b)中的一方的制动臂进行驱动的第1制动臂操作部(15A);以及在延长制动臂(30A、30B)之间对另一方的制动臂进行驱动的第2制动臂操作部(15B)。
