PRODUCTS & CASES

This double girder overhead crane series strictly follows European FEM and DIN industrial standards throughout design and production, with the maximum rated lifting capacity reaching 800 tons. Its hoist trolley is embedded in the gap between two main girders, which effectively expands the horizontal travel stroke of lifting attachments. Featuring steady dependable performance, wide application flexibility, intuitive operation and simplified maintenance, it becomes a premium heavy-duty lifting option for standardized high-end factories.

Lightweight & Modular Integrated Design

1. The overall vertical height of the crane body is cut by 20%–25% compared with conventional overhead crane models

2. Self-weight of the whole machine is reduced by 20%–30% to lighten structural load

3. Maximum wheel pressure is lowered by 15%–20%, minimizing bearing requirements for factory buildings

4. Compact limiting dimensions enlarge the effective working coverage of each lifting cycle

5. Light integral framework slashes civil engineering investment for new workshop construction

6. All spare parts adopt standardized serial design with high interchangeability for easy replacement

7. Modular split layout shortens packaging volume and facilitates long-distance transportation

8. Unified standardized module production guarantees consistent product quality and speeds up delivery lead time

1. All steel plates undergo full sandblasting pretreatment to achieve Sa2.5 surface cleanliness grade

2. CNC numerical cutting equipment processes girder web plates to deliver smooth, dimensionally accurate curved profiles

3. Automatic submerged arc welding forms all structural seams; every weld joint passes ultrasonic and X-ray non-destructive flaw detection

4. Main girders and trolley assemblies are machined via floor boring and milling machines to maintain ultra-flat assembly reference surfaces

Outstanding Operational Reliability

1. Imported driving motors with Class F insulation and IP54 ingress protection, fitted with real-time overheat alarm function. Aluminum alloy stretch protective shells deliver excellent heat dissipation for stable long-hour operation

2. Germany-originated speed reducers equipped with surface-hardened gears that bear heavy impact loads; fully sealed construction prevents grease leakage

3. Core electrical hardware sourced from top international brands including Siemens, Schneider and ABB, with a minimum IP54 protection rating

4. Travel wheels forged from 65Mn alloy steel, featuring strong wear resistance, anti-fatigue performance and extended service lifespan

5. Low power consumption and maintenance-free core transmission assemblies

6. The complete crane realizes roughly 30% overall energy savings versus traditional heavy lifting equipment

7. All-in-one integrated transmission structure reduces power loss and improves circulation efficiency

8. Variable frequency speed regulation system supports a 1:10 wide speed ratio between high and low rotation speeds, boosting comprehensive handling efficiency by over 20%

9. Fewer vulnerable wearing parts simplify daily inspection and lower regular maintenance expenditures

10. Sophisticated production processes paired with premium imported core components drastically cut equipment failure frequency and overall operating costs
