Heavy-Duty Scraper Mixer Drive — Selection guide

HDS — Selection Workflow

Selecting a HDS gearbox starts with five inputs: motor power, input speed, output speed (or ratio), output torque, and duty profile. CHINFAR's engineering team validates each selection against the load spectrum and operating environment before quotation.

Required inputs

1. Motor nameplate: power (kW), speed (rpm), service class
2. Driven machine: type, daily operating hours, start/stop frequency
3. Transmission: coupling or belt drive, output shaft orientation
4. Ambient conditions: temperature, dust, moisture, ATEX zone (if any)
5. Mounting: foot, flange, shaft-mounted, or torque-arm

Engineering review

Each submitted inquiry is reviewed by our application engineers. Selection is confirmed against thermal capacity, mechanical strength, and service factor before quotation.
