Relying on SZW's 200-year heritage in transmission technology and combining this technology edge with our own strong manufacturing capabilities, Henan Sanzhi Machinery Co., Ltd. provides customized non-standard solutions for our clients. We can tailor-design hoists, trolleys, and single-girder or double-girder cranes according to the working conditions, space constraints, load requirements, and environmental factors of various industries (such as metallurgy, mining, hoisting, and logistics). From parameter selection and 3D modeling to finite element analysis, we ensure that every customized product seamlessly integrates with the client's production line, achieving optimal transmission efficiency and maximum service life. Whether it is new product development or retrofitting existing equipment, we offer full-cycle custom support from design to delivery.

We have established a one-stop service system that covers the entire project lifecycle. From preliminary technical consultation, solution planning, and product selection, to mid-stage transportation, installation and commissioning, and system integration, as well as later-stage operation monitoring and maintenance-all are coordinated and managed by a professional team. Customers only need to interface with a single contact point to resolve all issues related to transmission equipment, significantly simplifying procurement and management processes and reducing overall operating costs. Our one-stop service not only includes hardware supply but also covers technical document delivery, on-site operation guidance, and long-term spare parts support, ensuring our customers enjoy a worry‑free, labor‑saving, and cost‑effective experience.

We have an experienced team of technical engineers who provide round‑the‑clock, multi‑level technical support, including:

Remote Diagnosis -Quickly identifying the cause of faults through video calls and packet data analysis.

On‑site Guidance -For complex issues, our engineers can arrive at the customer's site within 48 hours.

System Optimization -Regularly evaluating operating parameters and providing recommendations for improving energy efficiency and extending service life.

At the same time, we commit to an immediate response to any malfunction-whether in a complete product or any individual component-not limited to reducers, but covering all transmission units and accessories. For example, when a reducer failed on Baosteel's hot rolling production line, we supplied a backup unit within 36 hours, preventing production stoppage, which fully demonstrates the timeliness and reliability of our technical support.

Henan Sanzhi Machinery Co., Ltd. offers a 24‑hour global response service for technical issues, providing both on‑site repair and remote technical assistance. In the event of critical failures, we guarantee the delivery of a backup unit within 48 hours. We are committed to an immediate response to any malfunction-whether in a complete product or any individual component.
