PRODUCT DETAILS

MG (A-type) double-girder gantry crane adopts a box-shaped double main beam welded structure and A-type outrigger design. It is manufactured in accordance with the GB/T 14406 "General Gantry Crane" standard. It consists of a bridge frame, gantry frame, lifting trolley assembly, electrical control system and operator’s cab, an electrical control system and a driver's cab. The whole machine has strong carrying capacity, stable operation and excellent wind resistance. It is suitable for material loading, unloading and lifting operations in open-air warehouses, freight yards, railway stations, port terminals and other places. It is the core equipment for medium-to-heavy-load and large-tonnage outdoor material handling.

Core advantages

High‑strength box‑shaped double‑beam structure. The main beam adopts a box-shaped double-beam welded structure, which has good overall rigidity and strong load-bearing capacity. After optimization by finite element analysis, it still maintains excellent bending and torsion resistance under large-tonnage and long-span working conditions, ensuring structural safety for long-term heavy-load operations.

FAQ

Q: Are you a trading company or direct crane manufacturer?

A:We are a professional crane manufacturer with 20-year industry experience and one of the leading enterprises in the hoisting equipment sector in South China. We operate two modern production bases in Jieyang, Guangdong and Changyuan, Henan, alongside a sales center in Foshan. Our full-chain capabilities cover R&D, design, manufacturing, sales, installation and after-sales service. You are welcome to arrange a video call or on-site factory audit at any time.

Q: Can you provide custom & non-standard crane solutions including OEM / ODM?

A:Yes. We offer over 30 series and nearly 1,000 product models, including overhead cranes, gantry cranes, jib cranes, electric hoists, metallurgical & explosion-proof cranes and intelligent logistics conveying equipment. Beyond standard models, we specialize in custom solutions for explosion-proof, precision-positioning and heavy-tonnage lifting scenarios. Flexible OEM & ODM services are available for branding, color, technical parameters and packaging.

Q: What standards, certifications and quality control do you apply for cranes?

A:Our design & production comply with ISO, FEM, DIN international standards. CE certification covering MD & LVD directives, together with full declaration and technical documents, can be provided for target markets. Strict full-process QC is implemented: 100% UT ultrasonic testing for main beam welds, motor load test, no-load & overload test before delivery. Each unit comes with independent QC inspection report.

Q: What about quotation terms, logistics, installation, after-sales and payment terms?

A:Our standard quotes apply EXW, FOB and other trade terms. We ensure safe delivery of goods to your nominated port.You may choose from two installation options: engineer on-site guidance, or remote support via drawings and videos.A 1-year warranty applies to the complete unit, alongside 7×24-hour remote after-sales service. We accept Sight L/C. Flexible payment terms are available for long-term partners.

Q: Can we visit your factory and review similar project references?

A:Absolutely. We welcome you to visit our two production bases in Guangdong and Henan, as well as our Foshan sales center — video factory audits can also be arranged if travel is not convenient. We have established stable cooperation with many large manufacturing enterprises and key engineering projects across China, and our products are progressively exported to markets along the "Belt and Road." Similar project references and client contacts can be shared upon request.
