Weitai Hydraulic stands as China's premier hydraulic authority. As the Secretary Company of the Shandong Hydraulic Association (SDHA), we represent the pinnacle of Chinese engineering. Our history spans decades of specialization in high-torque final drives and travel motors for global heavy machinery brands like SDLG, XCMG, and SANY.
Quality is non-negotiable. Our manufacturing facilities are ISO 9001 certified, and our component supply chain is strictly vetted with CE, RoHS, CSA, and UL certifications. We don't just supply parts; we supply guaranteed uptime for construction, mining, and industrial sectors.
Initially founded as a dedicated OEM factory, Weitai has evolved into a global titan. With a production volume exceeding 40,000 travel motors annually, our designs are trusted by SDLG for their excavators and loaders, ensuring seamless compatibility and superior volumetric efficiency.
The core of an SDLG machine's mobility lies in its Final Drive Motor. Weitai’s technical roadmap focuses on three pillars: High Power Density, Thermal Management, and Precision Planetary Reduction.
Our latest WTM series utilizes swash-plate axial piston designs that minimize friction and maximize torque output even at low RPMs. This is critical for SDLG excavators operating in rugged terrains.
Utilizing high-strength alloy steels and specialized heat treatment (Carburizing & Quenching), our gearboxes withstand extreme shock loads common in demolition and rock handling.
Future-ready final drives now incorporate multi-lip dynamic sealing systems, preventing hydraulic fluid contamination—the #1 cause of field failure in construction machinery.

Shandong is the epicenter of China's heavy equipment manufacturing. By being at the heart of this ecosystem, Weitai manages a lean supply chain that reduces lead times by 30% compared to European counterparts. Our proximity to material suppliers and specialized casting foundries allows for rapid prototyping and mass-scale OEM customization.
Our warehouse in Qingdao utilizes advanced ERP systems to maintain a buffer of common final drive models (WTM-09, WTM-75), ensuring that global distributors can receive stock within days, not months.
SDLG equipment is deployed globally, requiring final drives that adapt to diverse climatic conditions. Weitai's hydraulic solutions are engineered for:
Region: Middle East / North Africa
Our motors feature enhanced cooling fins and dust-proof dual-cone seals to survive the abrasive nature of desert sand and ambient temperatures exceeding 50°C.
Region: Russia / Canada / Northern Europe
Using low-viscosity hydraulic fluid compatibility and specialized metallurgy to prevent "cold-cracking" of the gearbox casing during winter startups.
Region: Southeast Asia / South America
Anti-corrosion painting and marine-grade coatings protect the final drive housing from salt-spray and high humidity, extending service life by 200%.





We participate in BAUMA, CONEXPO, and PTC Asia annually to stay connected with our global clients and showcase our latest hydraulic innovations.
The hydraulic industry is entering a "Green Era." At Weitai, we are currently developing Integrated Electric Wheel Drives (WED Series) which combine electric motors with planetary gearboxes. This technology is designed for the next generation of electric SDLG mini-excavators and loaders. By eliminating hydraulic lines, we reduce leak risks and improve energy efficiency—paving the way for autonomous construction fleets.
