In a new video from Ringfeder, the company explores the types of couplings that excel in crane and hoist applications. Ideal for heavy-duty equipment, barrel couplings are highly robust and torsionally stiff. They also compensate for misalignment and are easy to assemble. The Ringfeder offering includes bore sizes up to 550 millimeters and torques up to 1,390,000 Nm — making these components suitable for ship cranes, cargo cranes, steel mill cranes, and more.
Also suitable for these applications is the gear coupling. This component transmits torque via hubs with crowned gear teeth, which are in permanent mesh with the straight gear teeth of the sleeves — providing the highest torque transmission for the smallest size.
