4 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
According to the directory reference, the lifting capacity ranges from 5 to 100 tonnes. However, the exact capacity depends on the specific model and configuration. Always verify with the manufacturer or supplier for the intended application.
The directory lists ISO 4301-1 for lifting capacity, duty class, and operating temperature, IEC 60038 for power supply, and GB/T 3811 for maximum wind speed. These standards serve as procurement references; compliance must be confirmed with the manufacturer.
Portal cranes can be operated via radio remote control or from a cabin. The choice depends on the application and operator preference. Both modes are listed in the directory reference.
The directory specifies a maximum wind speed of 20 m/s for out-of-service conditions, based on GB/T 3811. This is a reference value; site-specific wind conditions should be considered and confirmed with the manufacturer.
