The auxiliary control circuit comprise a control power supply, a normally-closed stroke switch (SQ), a normally-closed stopping button switch (SB), and a coil of a control relay (KA), wherein the control power supply, the normally-closed stroke switch (SQ), the normally-closed stopping button switch (SB), and the coil of the control relay (KA) are connected in series. Two ends of the coil of the control relay (KA) are in parallel connection with normally-open self-locking contacts of the control relay (KA). The main control circuit comprises a coil of a main control contactor (KM) connected with a power supply output circuit in series, and a normally-open contact (KA2) of the control relay of the auxiliary control circuit. A main control contact of the main control contactor (KM) is connected in series with a power supply circuit of a lifting motor. The building hoist fingerprint starting safety device further comprises a fingerprint collection identification device (ZW). A normally-open contact (KZ) is arranged at the output end of the fingerprint collection identification device (ZW) and is arranged in series in the auxiliary control circuit. Only an authorized person can start the building hoist fingerprint starting safety device. The building hoist fingerprint starting safety device is high in safety and reliability, and is more ideal in utilization effect.
