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 frame is designed to meet ISO 3471 for rollover protective structures and ISO 3449 for falling object protective structures. These standards define performance requirements such as load capacity and impact energy absorption. Always verify compliance with the manufacturer for the specific model.
Common materials include high-strength steel and alloy steel, with grades such as Q345B to Q460C per GB/T 1591. The choice of material affects strength and weight. Confirm the exact grade with the supplier.
Frame dimensions are customizable to cab size, typically ranging from 1200–2500 mm in length, 1000–2000 mm in width, and 1500–2500 mm in height. Consider the cab's internal space and mounting requirements. Consult the manufacturer for fitment.
Regularly inspect for cracks, deformation, or corrosion. Check weld integrity and surface coating. If damage is found, consult the manufacturer for repair or replacement. Do not modify the frame without approval, as it may compromise safety.
