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.

    本发明公开了一种建筑机械起重机的制动装置,包括横架,所述横架的底部两端均设有支撑柱,所述支撑柱的底部均设有支撑座板,所述支撑座板的底部均设有万向轮,所述横架的底部中心处设有吊起部,所述吊起部的底部设有固定块,所述固定块的底部中心处设有吊钩,所述固定块的两侧均设有连接杆一,所述连接杆一远离所述固定块的一端均设有连接杆二,所述连接杆二远离所述连接杆一的一端均设有自动收放轮,所述自动收放轮的两侧均设有减速机构,所述减速机构分别固定在所述支撑柱侧边。有益效果:增加阻力,避免吊起部在落料过程中速度过快,防止安全事故的发生。
