Abstract
Auxiliary device for lifts, whose purpose is to prevent the elevator from standing between two floors due to breakdown or supply failure, leading it towards the nearest silver preferably downwards, it is essentially characterized by being an auxiliary motor powered by direct current of a battery, which is always charged from the network by means of a rectifier, also presenting two relays, one of lack of current that works in alternating current, the voltage of the power supply network and another auxiliary that works in direct current to the voltage of the battery, also incorporating the electrobrake of the elevator a coil with operation to the voltage of the battery.
