HSE-2 Series Slew Drives: Dual-Worm High-Load Precision for Demanding Applications
What is an HSE-2 Series Slew Drive?
The HSE-2 Series Slew Drive is a dual-worm, heavy-duty rotational drive system that combines two worm shafts and a slewing bearing into a high-stability, enclosed structure. An evolution of the HSE series, the HSE-2 is engineered for applications that demand elevated torque capacity, greater mechanical efficiency, and superior self-locking performance—especially under extreme axial and tilting moment loads.
By integrating two worm gears positioned at 90° to one another or in parallel configuration, the HSE-2 offers higher transmission ratios and better load balancing, reducing gear stress and increasing drive longevity.
Key Features and Engineering Advantages
Dual-Worm Gear Mechanism
Two worm gears work in tandem to distribute torque more evenly, reduce backlash, and improve load-carrying performance.
Enhanced Self-Locking Capability
Ideal for aerial lifts, lifting platforms, and equipment on inclined planes where back-driving must be prevented for safety.
Heavy-Load and Shock-Resistant Housing
The reinforced, enclosed housing is designed for IP66–IP67 protection, supporting extreme weather, vibration, and chemical exposure.
Precision Rotation with Dual-Motor Option
Dual input shafts allow for synchronized dual-motor control or redundancy in mission-critical applications.
Extended Life in Harsh Conditions
Advanced sealing, synthetic lubrication, and wear-resistant materials ensure durability in demanding work environments.
Application Scenarios
Aerial Working Platforms and Firefighting Cranes: Secure load retention with dual braking and redundancy.
Defense and Surveillance Systems: Stability under vibration and multi-angle positioning for antennas and weapons.
Offshore Lifting Equipment: Dual-locking against wave movement and strong winds.
High-Capacity Solar Trackers: Reliable actuation for large heliostats or dual-axis fields.
Mining and Earthmoving Machinery: Built for intense vibration and high-shock torque transfer.
