specific Embodiment approach

[0009] In the figure, it is composed of a retaining bar (1), a limit post (2), a spring (4) and a normally closed switch (3). The bar (1) moves along the limit column (2). Under normal circumstances, the bar (1) does not touch the normally closed switch (3). The elevator power supply is connected to the circuit. When there is an obstacle, the bar (1) is compressed, (1) Move and compress the normally closed switch (3), so that the normally closed switch (3) cuts off the elevator motor power supply at the normally open position.

[0010] When the elevator is installed and maintained, the anti-rolling device is installed on the upper end of the elevator car door device and the lower end of the car toe guard.
