Production Line

Henan Zehua Heavy Machinery Co., Ltd. operates a state-of-the-art, fully integrated production line that transforms raw steel into high-precision, reliable, and intelligent cranes. The entire manufacturing process is designed to meet international standards, with each stage carefully controlled to ensure exceptional quality, efficiency, and traceability.

1. Raw Material Inspection and Preparation

Every batch of steel plates and structural components undergoes rigorous incoming inspection, including chemical composition analysis and mechanical property testing. Only materials that meet strict quality criteria enter the production line. Steel coils are processed through a high-performance leveling machine equipped with 15 forged 60CrMo steel rollers (180mm diameter, 260kW power), ensuring perfectly flat plates for subsequent cutting and welding.

2. Laser Cutting and Blanking

Zehua's blanking workshop features advanced laser cutting technology as its core. A 31.5-meter large-scale laser plate cutting machine, sourced from a top global brand, performs one-time cutting of entire main girder side boards. This eliminates the need for multiple welding seams, significantly improving structural strength and aesthetic appearance. The machine can cut steel plates up to 40mm thick and handle complex groove cutting, chamfering, and intricate geometric shapes. For profile steel processing, an automatic loading laser cutting system ensures high efficiency and micron-level precision, reducing material waste and shortening production lead times.

3. Robotic Welding and Assembly

Zehua has deployed multiple intelligent welding robots across its assembly lines. These robotic systems ensure consistent, repeatable, and high-strength welds on crane girders, end carriages, and structural components. Each weld is monitored in real time, and parameters such as current, voltage, and travel speed are automatically adjusted to maintain optimal penetration and bead appearance. After welding, all critical joints undergo non-destructive testing (NDT), including ultrasonic and magnetic particle inspection, to verify zero internal defects.

4. Shot Blasting and Surface Preparation

To eliminate internal stresses induced by welding and cutting, every crane beam box passes through a large shot blasting machine with a chamber opening of 2500mm (width) × 3200mm (height) and a cleaning length of 33,000mm. Powered by 265kW and equipped with 16 high-velocity shot blasters, this machine uniformly impacts the entire surface of the workpiece, removing mill scale, rust, and welding spatter while creating a textured profile that maximizes paint adhesion. The shot blasting process is essential for extending crane service life, especially in corrosive environments such as ports, shipyards, and chemical plants.

R&D (Research and Development)

Innovation is the engine that drives Henan Zehua Heavy Machinery Co., Ltd. Despite being founded in 2020, the company has placed research and development at the very core of its business strategy. Zehua's R&D department is staffed by veteran engineers who previously worked at China's state‑owned crane factories, bringing with them more than 30 years of accumulated knowledge in mechanical design, structural analysis, control systems, and materials science. This rare combination of legacy expertise and modern technology allows Zehua to push the boundaries of what cranes can achieve.

R&D Organizational Structure

Zehua's R&D team is organized into four specialized groups:

• Mechanical Engineering Group: Focuses on structural design, finite element analysis (FEA), fatigue life prediction, lightweight optimization, and material selection. This group uses advanced simulation tools like ANSYS and SolidWorks Simulation to validate designs before physical prototyping.

• Electrical and Control Systems Group: Develops PLC programs, frequency converter integration, sensor networks, and safety logic circuits. This group is responsible for implementing anti-sway algorithms, collision avoidance systems, and synchronized multi-crane coordination.

• Intelligent and IoT Group: Designs cloud‑based remote monitoring platforms, predictive maintenance algorithms, and data analytics dashboards. This group enables Zehua's intelligent cranes to report real‑time operating parameters, receive over‑the‑air software updates, and alert service teams before failures occur.

• Applications and Testing Group: Conducts prototype testing, field validation, and failure analysis. This group also works closely with customers to document real‑world operating conditions and translate field feedback into design improvements.

At Henan Zehua Heavy Machinery Co., Ltd., the driving force behind every safe, reliable, and intelligent lifting solution is a team forged from decades of hands‑on industry experience. Unlike many new manufacturers that start from scratch, Zehua’s core production and management team originates directly from former state‑owned crane factories — the very institutions that built the foundation of China’s heavy machinery sector. Collectively, these professionals bring more than 30 years of practical experience in scientific research, product design, manufacturing processes, quality control, and factory operation management.

The team is organized into four core pillars:

1. R&D and Engineering Group – Responsible for finite element analysis (FEA), structural optimization, and the development of smart crane features such as anti‑sway algorithms, remote monitoring, and predictive maintenance. Many members hold advanced degrees in mechanical engineering and have participated in national crane standard drafting committees.

2. Production and Quality Control Group – Oversees the entire manufacturing process, from laser cutting of main girder plates to robotic welding and shot blasting. This group strictly follows ISO 9001, ISO 14001, and ISO 45001 standards. Each welding station is manned by certified international welders, and every crane undergoes rigorous non‑destructive testing (NDT) before leaving the workshop.

3. Technical Support and After‑Sales Service Group – Composed of field engineers who have installed and commissioned cranes in more than 120 countries. They provide free technical consultation, on‑site installation guidance, emergency repair services, and operator training. The group guarantees a response within 24 hours for domestic clients and 48 hours for international clients.

4. Global Sales and Project Management Group – A multilingual team that understands both technical specifications and cross‑cultural business practices. They work closely with clients from the Middle East, Southeast Asia, Africa, and the Americas to deliver tailor‑made lifting solutions.

Company History of Henan Zehua Heavy Machinery Co., Ltd.

Henan Zehua Heavy Machinery Co., Ltd. was founded in 2020 in Xinxiang City, Henan Province — a region widely recognized as the birthplace of China's crane industry. Although the company itself is relatively young, its establishment was built upon decades of accumulated expertise. The core production and management team all came from former state-owned crane factories, bringing with them more than 30 years of hands-on experience in research and development, precision manufacturing, and factory operations. This unique heritage gave Zehua a head start that most startups lack.

The Founding Vision (2020)

In its founding year, Zehua identified a gap in the global lifting equipment market: customers demanded not only high-performance cranes but also integrated solutions that are safe, intelligent, and reliable. With an initial investment of over 50 million RMB, the company acquired a 220,000-square-meter manufacturing campus in the Xinxiang Advanced Manufacturing Development Zone. A dedicated 24,000-square-meter workshop was designed specifically for overseas orders, equipped with environmental controls to ensure uninterrupted production regardless of weather conditions. The company set its core mission from day one: "Create the top quality crane from China; care the carrying safety for the world."

Building a World-Class Production System (2020–2021)

During its first 18 months, Zehua focused on building a production system that could compete with international leaders. The company made significant investments in high-end machinery. A 31.5-meter large-scale laser plate cutting machine was installed, capable of cutting an entire main girder side board in a single pass — a process that drastically reduced welding seams and improved structural strength. This machine also supported 40mm thick plate cutting with groove functions, enabling complex fabrication tasks. Simultaneously, Zehua added a large shot blasting machine with a 2500mm×3200mm chamber opening and a cleaning length of 33,000mm, allowing integral shot blasting for crane beam boxes to eliminate internal stress and enhance paint adhesion. Multiple welding robots were introduced to ensure consistent, high-precision welding. By the end of 2021, the company had built an industry-leading intelligent production line.

Certifications and Quality Milestones (2021–2022)

Quality has always been at the core of Zehua's strategy. The company pursued and quickly obtained ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health and Safety Management) certifications. To prove its products met rigorous international standards, Zehua also earned TÜV, CE, and SGS certifications, along with international welder qualification certificates. These credentials opened the doors to demanding markets in Europe, the Middle East, and Southeast Asia.

Expanding Product Portfolio (2022–2023)

From 2022 onward, Zehua systematically expanded its product lines beyond conventional overhead cranes. The company developed intelligent cranes equipped with IoT-based remote monitoring, anti-sway technology, and predictive maintenance modules. Multi-functional special cranes were introduced for electrolytic aluminum/copper smelters, roasting plants, material suction applications, and stacking operations. Port cranes, ship cranes, and metallurgical cranes (such as ladle cranes) were added to serve heavy industries. These products quickly found applications in machinery manufacturing, steel metallurgy, electric power plants, railway construction, aerospace assembly, port logistics, petroleum and chemical complexes, and even nuclear power facilities.

Going Global (2023–2024)

With a full product portfolio and proven quality, Zehua accelerated its international expansion. The company participated in major industry exhibitions in Germany, Turkey, and the United Arab Emirates. By 2024, Zehua's products were being exported to more than 120 countries and regions, covering key markets in the Middle East (Saudi Arabia, UAE, Qatar), Southeast Asia (Indonesia, Thailand, Vietnam), Africa (Nigeria, Egypt, South Africa), and the Americas (Brazil, Argentina, and the United States). To support global customers, Zehua established a "one-stop worry-free service" network, offering 24/7 technical support, on-site installation guidance, and rapid spare parts logistics.
