Explore our core WL20 and corresponding hydraulic configurations optimized for high-torque applications in unforgiving regional environments.
The Central African Republic (CAR) presents one of the most demanding operational environments globally for mobile and stationary hydraulic systems. Rich in raw natural resources—including forestry reserves, timber, alluvial gold, and diamond deposits—the country's extractive and construction sectors demand components that can function reliably under extreme ambient temperatures, humidity, and constant physical stress.
Extractive operations in sites near Ndassima, or timber logging in the south-western rainforest zones, require equipment that minimizes downtime. Maintenance facilities are often far from operational zones, meaning that high mechanical durability is not just a preference; it is a critical project requirement. Heavy machinery like excavators, drilling rigs, concrete placement booms, and specialized forestry cranes rely heavily on high-torque, double-helical actuator configurations to survive the local operational stresses.
The WEITAI WL20 helical rotary actuator is designed to convert linear piston motion into high-torque angular rotation. Through its fully enclosed sliding-spline engineering, the WL20 series offers high performance in space-critical applications.

Unlike traditional hydraulic cylinders that require complex linkages, pins, and external guide rails, the WL20 utilizes multiple helical gears (helical spline mechanism). As the piston moves linearly within the cylinder body under oil pressure, the helical gears force the output shaft to rotate. This configuration delivers three primary operational advantages:
From custom hydraulic cylinder fabrications to integrated planetary and helical designs, our R&D team designs solutions for top global machinery brands.
Every single WL20 series helical actuator undergoes 100% pressure and torque testing before being packaged for international transit.
Our raw material suppliers and assembly plants conform to global compliance standards, including CE, RoHS, CSA, and UL certifications.
Exporting mechanical assemblies to landlocked countries like the Central African Republic requires careful planning. Most machinery parts enter the CAR through the Port of Douala in Cameroon, followed by overland transport along the Douala-Bangui corridor. This route requires secure industrial packaging to protect shipments during long transits over challenging terrain.
WEITAI secures all shipments using heavy-duty, sea-worthy wooden crates with internal protective barriers to prevent humidity-induced oxidation during ocean shipping and overland transport. We also supply all necessary documentation, such as clean bills of lading, certificates of origin, and pre-shipment inspection papers (e.g., SGS or Bureau Veritas, depending on import requirements), to ensure a smooth customs clearance process at the Bangui border posts.

Our heavy-duty actuators are engineered to perform in key industrial sectors throughout the region.
In the rainforest timber concessions of the south, wood grappling loaders and log forwarding cranes require high torsional force. The WL20 series offers compact 360-degree rotation, enabling operators to handle heavy timber logs in tight spaces without the maintenance issues associated with open-gear systems.
Diamond and gold mining operations near Ndassima require excavators and washing plant feeders to work continuously under harsh conditions. The WL20’s fully sealed design prevents dust, mud, and water from damaging internal parts, helping to keep operations running smoothly.
Developing overland transport networks is critical for regional economic growth. Motor graders and utility excavation attachments equipped with WL20 actuators allow for precise positioning of grading blades and tilting buckets, helping crews build and maintain reliable roadways.
Utility vehicle manufacturers in Bangui use our actuators for precise rotation in work platforms and aerial lifts. The actuator's smooth, drift-free rotation and high holding torque help protect personnel working at heights.
