The invention discloses a building machinery crane braking device which comprises a transverse frame, supporting columns are arranged at the two ends of the bottom of the transverse frame, supporting seat plates are arranged at the bottoms of the supporting columns, universal wheels are arranged at the bottoms of the supporting seat plates, a lifting part is arranged in the center of the bottom of the transverse frame, and a fixing block is arranged at the bottom of the lifting part. A lifting hook is arranged at the center of the bottom of the fixing block, first connecting rods are arranged on the two sides of the fixing block, second connecting rods are arranged at the ends, away from the fixing block, of the first connecting rods, automatic winding and unwinding wheels are arranged at the ends, away from the first connecting rods, of the second connecting rods, and speed reducing mechanisms are arranged on the two sides of the automatic winding and unwinding wheels. The speed reducing mechanisms are fixed to the side edges of the supporting columns respectively. The device has the beneficial effects that the resistance is increased, the overhigh speed of the hoisting part in the blanking process is avoided, and safety accidents are prevented.
