Both disc brakes and drum brakes are widely used on overhead and gantry cranes, and “better” depends on the duty profile and environment. rem cakram 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.
Rem tromol (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.
Pemilihan harus didasarkan pada torsi yang dibutuhkan, energi berhenti, siklus tugas (berhenti/jam), kecepatan poros, batasan ruang, dan paparan debu, kelembapan, atau korosi. Rem crane terbaik adalah yang ukurannya sesuai untuk torsi dan beban termal.
