Both disc brakes and drum brakes are widely used on overhead and gantry cranes, and “better” depends on the duty profile and environment. Scheibenbremsen 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.
Trommelbremsen (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.
Die Auswahl sollte durch das erforderliche Drehmoment, die Bremsenergie, den Einsatzzyklus (Stopps/Stunde), die Wellen-geschwindigkeit, Platzbeschränkungen sowie die Exposition gegenüber Staub, Feuchtigkeit oder Korrosion bestimmt werden. Die beste Kranbremse ist die, die sowohl für Drehmoment als auch für thermische Belastung richtig dimensioniert ist.
