The spreader frame is the main structural component that supports and integrates all other parts of a spreader machine, such as the hopper, conveyor, and spreading mechanism. It transfers operational loads to the ground and maintains alignment between components.
Spreader frames are typically made from high-strength steel or alloy steel. Material grades may range from Q235B to Q345B as per GB/T 1591, but the exact grade should be confirmed with the manufacturer for the specific model.
Reference ranges for spreader frames are: length 3000–12000 mm, width 1500–3000 mm, height 500–1500 mm, and weight 500–5000 kg. These are general ranges; actual dimensions depend on the machine design and application.
Verification involves checking material certificates, weld quality per ISO 5817, surface treatment per ISO 8501-1, paint thickness per ISO 19840, and the listed dimensional tolerances, with ISO 2768-2 retained only for the hole-position reference. Always confirm compliance with the manufacturer or supplier.
