Engineered for high torque applications requiring exact positioning and robust performance in extreme marine and industrial environments across Hai Phong port networks.
As Vietnam's northern maritime gateway, Hai Phong is undergoing an unprecedented wave of modernization. From the expansion of the Lach Huyen Deep-Sea Port to the dynamic growth of the Dinh Vu-Cat Hai Economic Zone, heavy manufacturing, logistics infrastructure, and shipbuilding demand next-generation engineering components.
The WL20 Series helical hydraulic rotary actuators serve as a critical link in this transformation. Traditional mechanical linkages and cylinder-based designs are being phased out in favor of compact, zero-drift helical gear systems. In maritime deck machinery, high-torque steering systems, and port material handling assemblies, our actuators solve the challenges of space constraint and salt-fog corrosion resistance.
How sliding-spline technology achieves massive torque outputs within a space-saving cylindrical chassis.
The internal helical splines convert linear piston motion into powerful rotary force. By dispersing high loads over several teeth contacts, the design ensures minimal wear and exceptional structural strength compared to traditional rack-and-pinion variants.
WL20 components deliver up to 4200 Nm of torque in an ultra-compact body footprint. This enables engineers in heavy steel yards and marine terminals to build slewing movements without massive mechanical linkages or outriggers.
Featuring tight tolerances and advanced seal configurations, our actuators exhibit zero internal bypass leakage. This guarantees high precision in holding stationary rotational angles under severe overhead load limits.
Deploying WL20 series actuators to power infrastructure, maritime projects, and automotive production.
At port terminals, container positioning requires rapid yaw and pitch control. WL20 series actuators are integrated directly into spreader assemblies and boom pivots, ensuring reliable service cycles under continuous harbor duty.
For the domestic marine industry in Hai Phong, helical actuators are used in cargo hatches, fold-down davits, steerable propulsion modules, and mooring winches to resist harsh salt water environments while maintaining optimal sealing.
Integrated in heavy-duty boom arms, mining excavation gear, and vehicle steering mechanisms, our actuators are built to endure intensive shock loads and extreme pressure peaks standard in large construction sectors.

Multiple helical gear actuators make it possible to produce and hold any intermediate angle of rotation with zero backlash. The sliding spline helical mechanism provides a much higher power density compared to rack-and-pinion designs, meaning a far smaller structural space is needed to achieve equal or higher torque.
Yes, we provide most relevant export documentation including Certificates of Analysis / Conformance (COA), detailed mechanical drawings, insurance records, certificates of origin (CO) for preferential tariffs, and Bill of Lading.
For prototype samples, the lead time is about 7 days. For mass production orders, the standard lead time is 20-30 days after receiving the deposit payment. Lead times become effective when we receive your deposit and you provide final technical drawing sign-off.
We provide a 1-year product warranty covering materials and workmanship. In the event of an issue, our professional technical team is available to assist and resolve customer concerns quickly to keep down-time to a minimum.
Yes, we require all international orders to have an ongoing minimum order quantity. For specific configurations, please contact our sales team. If you are looking to purchase smaller retail quantities, we recommend looking at local regional dealers or checking our updates online.
We accept wire transfers directly to our bank account, Western Union, and PayPal. The standard term is a 30% deposit in advance, with the 70% balance paid against the copy of the Bill of Lading (B/L).
