In applications such as road construction, mining, and agricultural fieldwork, various mobile machinery and specialized equipment are constantly exposed to harsh operating conditions—including high dust levels, moisture and standing water, oil contamination, and rough terrain with constant vibrations. Conventional hydraulic motors are highly prone to wear, oil leaks, and stalling, which not only reduce operational efficiency but also pose safety hazards such as equipment slippage and load drops. Thanks to its robust body structure, excellent environmental adaptability, and the core advantage of an optional integrated parking brake, the OMR Orbital Motor perfectly meets the operational needs of various engineering, sanitation, agricultural, and material-handling equipment, making it the preferred choice for equipping and upgrading mobile hydraulic systems. HANJIU has specialized in the R&D and manufacturing of cycloidal hydraulic motors for many years, specifically optimizing product design and performance to provide reliable hydraulic power solutions for equipment across various industries.
For mobile machinery such as road rollers, skid-steer loaders, and road sweepers, the OMR Orbital Motor demonstrates exceptional adaptability to harsh environments. These types of equipment operate long-term on construction sites, in mines, and on farmlands, where dust, mud, and oil continuously erode equipment components. Conventional motors suffer from poor sealing performance and insufficient structural strength, making them highly prone to issues such as seal aging, contamination ingress, premature wear, and oil leaks—all of which lead to frequent downtime for repairs. The OMR Orbital Motor features a reinforced, one-piece housing design paired with a high-quality multi-seal system. It offers excellent resistance to wear, contamination, and aging, effectively preventing dust, moisture, and oil from entering the motor’s interior. Even when subjected to prolonged operational jolts and high-frequency vibrations, it maintains stable power output, significantly reducing the likelihood of failure. HANJIU rigorously selects materials for its core components, enhancing the motor’s overall strength and fatigue resistance from the source. This ensures the product is perfectly suited for a wide range of demanding outdoor operating conditions, effectively reducing downtime and associated losses.
Compared to standard motors, the OMR orbital motor—which features an integrated parking brake—is an essential component for specialized equipment such as aerial work platforms, winches, forklifts, and precision machine tools, effectively resolving safety challenges related to load positioning and slip prevention during parking. This motor features a multi-disc brake structure with spring-applied, hydraulically released operation and employs a normally closed positive braking design, ensuring safe and stable operation: During operation, hydraulic pressure pushes the brake springs apart, unlocking the brake and allowing the motor to run normally; When the equipment is shut down or the hydraulic system loses pressure, the spring automatically compresses the friction plates, instantly locking the motor’s output shaft and securely holding the workload in place. This eliminates safety hazards such as platform rotation drift, heavy loads falling from winches, and equipment slipping while parked. Additionally, the brake mechanism is automatically lubricated by the equipment’s drain oil, eliminating the need for separate maintenance or oil changes, resulting in simple operation and maintenance as well as a longer service life. HANJIU employs an integrated design that tightly integrates the motor and brake mechanism. The compact body saves space and eliminates the need for additional brake components, facilitating equipment manufacturers’ overall layout planning, modifications, and upgrades.
This OMR orbital motor offers exceptional compatibility and can be adapted to both open and closed hydraulic circuits, covering a wide range of equipment applications. It is ideal for both bulk installation in new machinery and for repair and replacement in older equipment. The product is available in a variety of displacement specifications with a wide range of torque and speed parameters, allowing it to precisely match the operational requirements of light- to medium-duty applications. It can provide stable drive power for municipal sanitation and field operations, as well as precise positioning for aerial work and lifting winches. HANJIU has established rigorous factory inspection standards. Every motor undergoes pressure testing, load testing, and actual braking lock tests to ensure sufficient braking torque and stable operational performance, thereby preventing defective products from leaving the factory.
For many years, HANJIU has consistently focused on the actual operational needs of its customers, continuously optimizing the durability and safety performance of its OMR orbital motors. The company has avoided the unnecessary piling up of features and instead focused on creating practical, stable, and safe high-quality hydraulic motors. At the same time, the company offers a comprehensive, one-stop technical service package, providing users with assistance in model selection and matching, installation and commissioning, troubleshooting, and guidance on routine maintenance—ensuring the efficient and safe operation of equipment in every aspect. Thanks to its robust adaptability to various operating conditions and reliable braking and safety features, the OMR orbital motor has gained widespread recognition from users both domestically and internationally, making it the ideal power component for equipment operating in harsh environments and performing specialized tasks.
