SAFETY BRAKE DEVICE FOR GANTRY CRANE

The utility model discloses a safety brake device for gantry crane which is a lifting mechanical cutout device used for construction. The safety brake device for gantry crane comprises a base, a fixed pulley, a safety steel cable, and a spring machine. The safety brake device is installed in the center of the upper part of the gantry elevator basket. By using the elasticity function of the spring and the tension function of the safety steel cable, the utility model makes the safety axis of the spring shrink freely. Simultaneously, the function of the basket braking and safety played by the existing structure of the gantry post of the elevator is also used. The lifting of the basket is flexible for installing the safety machine. When the critical states that the steel cable breaks or the steel cable skids out of the overhead pulley or the basket breaks away appear, the basket can stop and lean on the gantry immediately. Accidental loss is avoided.
