DHHI Germany GmbH

What DHHI Germany GmbH does

DHHI Germany GmbH is the German subsidiary of Dalian Huarui Heavy Industry Group Co., Ltd. (DHHI Group), a Chinese industrial conglomerate with approximately 100 years of history headquartered in Dalian. Operating from its office in Bochum, Germany, the subsidiary acts as the European interface between customers and the parent company's Chinese headquarters, providing design, development, and distribution of wind turbine gearboxes and drivetrain components. The company's core product is wind main gearboxes covering power classes from 750kW up to 12MW, with the current typical range at 3MW to 12MW targeting multi-megawatt onshore and offshore turbines. The product portfolio extends to pitch drives, yaw drives, rotor hubs, main frames, hydraulic systems, brakes, cooling systems, and controls and converters, enabling the company to offer complete drivetrain solutions.

The company employs a platform strategy that allows rapid customization of existing gearbox designs across multiple power classes, supplemented by proprietary simulation methods and calculation approaches developed in-house. Engineering tooling includes KISSsoft/KISSsys for gear calculations, AutoCAD and CATIA for 2D and 3D CAD, and Multi-Body Simulation and Finite Element Method analysis for drivetrain optimization. DHHI Germany positions itself as a development partner to wind turbine manufacturers and engineering offices rather than a pure component supplier, offering joint drivetrain optimization and damage analysis support.

The business model is enterprise B2B, with direct sales engagement to European wind turbine OEMs and engineering bureaus. Revenue is generated through hardware sales of gearboxes and drivetrain components on a quote-based, project-specific basis. The subsidiary leverages local German-language technical and commercial communication, while manufacturing is coordinated with the Chinese parent. DHHI Germany is a member of BEW (German Wind Energy Association) and DIN (German Institute for Standardization), and the company is led by Managing Directors Qinglong Meng and Cong Wang.
