Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | N/A (structural component, not pressure vessel) |
| other spec: | Max vertical load: 1-50 tons (depending on design), Max horizontal force: 10-30% of vertical load, Deflection limit: L/500 to L/1000 |
| temperature: | -40°C to +80°C (standard steel), -60°C to +150°C (special alloys) |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

1 company lists 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.
The mast/column is the vertical structural element that supports the jib arm and hoist, transferring loads to the foundation and ensuring stability during lifting operations.
Typical materials include structural steel and high-strength alloy steel, with grades such as Q235B to Q355B, as listed in the directory.
Key parameters include rated capacity, height, diameter, wall thickness, material grade, surface treatment, coating thickness, tolerances, operating temperature, wind load, seismic resistance, and weight. These must be confirmed for the specific crane model and application.
The component is typically blast cleaned to Sa2.5 and coated with a dry film thickness of 80–120 μm, per ISO 8501-1 and ISO 19840, respectively.
