Electromagnetic elevator brake |
| 摘要 |
An elevator brake is provided with a redundant means to release the brake to allow an elevator cab to move when a primary releasing means, such as a coil, does not release when desired. When the coil is deenergized or defective, an auxiliary coil is used to release the brake and enable the cab to move.
