FAQ

1. What is a double-girder overhead crane?
It has two parallel main girders on elevated rails, offering higher capacity, stability, and hook height than single-girder cranes.

2. What are the typical capacity and span ranges?
Capacities: 5–550 tons (custom available). Span: 10–50 meters. Selection depends on max load and runway width.

3. Which standards and certifications apply?
Key standards: ISO 8686, FEM 1.001. Regional compliance (CE, local codes) is required, with conformity and test certificates provided.

4. What is Duty Class (e.g., FEM M4-M8)?
Indicates workload frequency and intensity: M4-M5 moderate use; M6-M8 heavy/continuous use. Correct class ensures safety and reliability.

5. What factors affect price?
Capacity, span, lifting height, duty class, control system, component quality, and special requirements (e.g., explosion-proof, cleanroom).

6. How is installation done?
Site prep → assembly → electrical installation → load testing → final safety inspection. Only approved cranes enter service.

7. Can the crane be customized?
Yes. Options include auxiliary hoists, anti-sway systems, special attachments, or designs for harsh environments, all compliant with safety standards.

8. What are key operation and maintenance tips?
Certified operators only; daily checks on wire ropes, brakes, and limit switches; avoid overloading; follow scheduled maintenance; keep complete equipment records.
