Both disc brakes and drum brakes are widely used on overhead and gantry cranes, and “better” depends on the duty profile and environment. Дисковые тормоза 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.
Барабанные тормоза (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.
Выбор должен основываться на требуемом крутящем моменте, энергии остановки, цикле работы (остановки/час), скорости вала, ограничениях по пространству и воздействию пыли, влаги или коррозии. Лучший крановый тормоз — это тот, который правильно подобран по крутящему моменту и тепловой нагрузке.
