The utility model discloses a lifting high-speed brake control circuit capable of avoiding contact adhesion of an output module with the advantages of ensuring normal production operations, raising production efficiency and reducing maintenance cost. A first lifting high-speed brake output contact of a lifting PLC (Programmable Logic Controller) output module is connected with the a coil of a first relay, a second lifting high-speed brake output contact of the lifting PLC output module is connected with the a coil of a second relay, a brake output contact of a dolly PLC output module is connected with a coil of a third relay, a normally open contact of the first relay is connected with a first lifting high-speed brake control contact of a lifting control circuit main contactor, a normally open contact of the second relay is connected with a second lifting high-speed brake control contact of the lifting control circuit main contactor, and a normally open contact of the third relay is connected with a normally open contact of a dolly control circuit main contactor. The lifting high-speed brake control circuit of the utility model raises service life of the output module, and reduces maintenance cost.
