Abstract
An emergency power operation apparatus of an elevator that operate machines in a firefighter operation according to the situation in a case where a power failure occurs during firefighter operations during a fire and a switchover to an emergency power source occurs. A group-management controller causes machines not in firefighter operation to preferentially return to an evacuation floor or a rescue floor when a power failure occurs during firefighter operations during a fire and then makes machines in firefighter operation operational. In a case where there are multiple machines in firefighter operation after all machines not in firefighter operation have finished returning to an evacuation floor or a rescue floor, if there is a machine at a standstill outside a door zone among the machines in firefighter operation, the group-management controller causes that machine at a standstill outside the door zone to preferentially become operational.
