Abstract

PURPOSE: To improve the thermal radiation of a brake durm by extending ribs to the opened side of the drum to form radiating fins and fixing each fin at an angle to exhaust the air inside a brake cover to the outside at the free-hole rotation of a hoisting drum.
CONSTITUTION: The periphery of a brake drum 21 is provided with a braking face for a brake 24 and the inside is provided with a torque-transmitting face 23 for a clutch 25. The closed side of the brake drum 21 is connected to a hoisting drum 26. A hollow part 29 is provided between the braking face 22 and the transmitting face 23, and both faces are connected by a plurality of ribs 30. Each rib 30 is fixed at an angle to exhaust the air inside a brake cover 28 to the outside through hollow part 29 at the free-hole rotation of the hoisting drum 26, and provided with a radiating fin 31 extended to the opened side of the brake drum 21.
