Direct Drive Motors are used for installations that require anti fall back devices. These are typically industrial roller doors and grilles, non counter balance and vertical lift doors.
The RDA1400 motor is equipped with a choice of mechanical or digital limits and a low level haul chain to be used in the event of power failure to open or close a door.
The motor is capable of lifting approx. 1500Kg's depending on door dimensions operating at 9rpm with a 55mm hollow bore.
