Selection focus for this working condition
Selection considers start frequency, blockage, torque limit and maintenance access.
Recommended coupling types Hydrodynamic couplings, elastic sleeve pin or jaw couplings, drum gear couplings, couplings with brake wheel or backstop, and grid couplings.
Typical working conditions Continuous duty, high start inertia, long-belt tension, multi-drive load sharing, and outdoor dust, humidity and temperature variation.
Key selection parameters Start time, torque limiting, thermal protection, low-speed high torque, brake and backstop torque, multi-drive synchronization and belt protection.
Installation and maintenance notes Check brake and backstop direction and capacity, monitor hydrodynamic coupling oil temperature and fusible plugs, verify load balance and install complete guards.
Use with caution / not recommended Long-distance or high-power belts should not use hard start plus rigid coupling; steep upward conveyors should not run without backstop protection.
