Compact 90° drive solutions for heavy-duty industrial applications
The HPR series right angle planetary gearbox is designed for equipment where installation space is limited but high torque, high reliability and precise control are required. By combining a compact 90° layout with modular planetary stages, HPR gearboxes provide a robust drive solution for demanding OEM machinery and retrofit projects.
Key Benefits for Your Project
- Space-saving 90° design
Input and output are arranged at right angles, allowing you to place the motor or hydraulic drive where space is available while keeping the output shaft exactly where the machine needs it. - Wide torque & ratio range
- Torque range: 200 N·m – 1,100,000 N·m
- Ratio range: i = 9 – 5000
One gearbox family covers everything from light duty equipment to heavy industrial drives.
- Modular, easy-to-configure structure
The HPR platform is built on a modular design, greatly reducing the number of unique parts. This means shorter lead times, easier spare-parts management and simplified maintenance for you and your customers. - Stable design, proven in long-term operation
The “solidified” design concept ensures that key internal components remain unchanged for years, giving users long-term interchangeability and reliable after-sales support.
Flexible Input Options
Select the input configuration that best matches your drive concept:
- Electric motor flange input – direct motor mounting, IEC or customized flanges
- Hydraulic motor input – for mobile and hydraulic-powered machinery
- Plain shaft input – for belt, chain or gear connections
- Brake input – integrated brake for safe stopping and holding
- Clutch or backstop options – for controlled start-up or back-rotation protection
This flexibility makes it easy to adapt the HPR gearbox to new machines or to upgrade existing equipment.
Versatile Output Interfaces
To match different machine designs, the HPR series offers multiple output forms:
- Locking disc output – for backlash-free, high-precision torque transfer
- Internal spline output – compact connection to mating shafts
- External spline output – for high-torque coupling solutions
- Flat key output shaft – easy, standardised mechanical connection
Whether you are driving drums, wheels, winches or various process shafts, you can choose the most efficient mechanical interface.
Typical Applications
HPR right angle planetary gearboxes are widely used in:
- Construction and engineering machinery
- Cranes, winches, hoists and lifting systems
- Conveyors, mixers, agitators and material handling equipment
- Steel, mining, cement and chemical process lines
- Marine and offshore equipment
- Any application where limited space and high torque must be combined
Designed for OEMs and System Integrators
For machine builders and system integrators, the HPR series offers:
- Standardised modules to simplify machine design
- High efficiency and long service life to reduce lifecycle cost
- Flexible customization of ratios, interfaces and accessories
- Strong after-sales support with long-term availability of parts
