Both disc brakes and drum brakes are widely used on overhead and gantry cranes, and “better” depends on the duty profile and environment. 디스크 브레이크 generally offer superior heat dissipation and more consistent torque at higher speeds, which makes them attractive for high-duty hoisting, frequent stops, and applications where stable braking performance is critical. They can also be easier to inspect and maintain in some layouts.
드럼 브레이크 (including electro-hydraulic block brakes) are extremely common in crane travel and hoist systems because they are rugged, proven, cost-effective, and tolerant of harsh industrial conditions. They often integrate well with electro-hydraulic thrusters and standard crane architectures.
선택은 필요한 토크, 정지 에너지, 작업 주기(정지/시간), 축 속도, 공간 제약, 먼지, 습기 또는 부식에 대한 노출에 따라 결정되어야 합니다. 가장 적합한 크레인 브레이크는 토크와 열 부하 모두에 적합하게 크기가 정해진 것입니다.
