This utility model provides a drum mechanism for lifting equipment, relating to the technical field of drum mechanisms. It includes a support frame, with a horizontal shaft rotatably mounted between the two sides of the inner wall of the support frame. A drum is fixedly fitted onto the middle of the horizontal shaft. Both ends of the horizontal shaft pass through the support frame, and a first bevel gear is fixedly fitted onto one end of the horizontal shaft. In this utility model, the operator starts a first motor, causing its output shaft to drive a second bevel gear to rotate. Under the meshing action of the second and first bevel gears, the horizontal shaft drives the drum to rotate, thus completing the lifting operation. The operator then starts the second motor, causing its output shaft to drive a lead screw to rotate. The rotating lead screw, through threaded advancement, moves a lifting plate, allowing the arc-shaped frame to engage with the horizontal shaft. This causes the horizontal shaft's rotation speed to decrease sharply and then stop, preventing the heavy object from falling further and avoiding a crash.
