Gantry Shear Working Process
1. Material Inspection
Scrap metal should be inspected before loading. Material dimensions, cross-section, thickness, hardness and internal construction must remain within the rated capacity of the selected gantry shear.
Sealed containers, pressure vessels, gas cylinders, batteries, fuel tanks, explosive items and hazardous materials must be removed or handled separately.
2. Material Loading
Prepared scrap is loaded into the feeding box by a grapple, crane or other suitable material-handling equipment. The feeding box dimensions and loading method are selected according to the scrap size and required capacity.
3. Hydraulic Compression
Hydraulic compression devices press loose or irregular scrap into a more manageable bundle. Compression helps control the material position and prepares it for stable feeding toward the cutting chamber.
4. Automatic Material Feeding
A hydraulic pusher or conveyor advances the compressed material toward the shear blade. The feeding distance can be adjusted according to the required cut length and material condition.
5. Hydraulic Shearing
The hydraulic cylinders drive the moving blade downward against the fixed blade. Concentrated hydraulic force cuts the prepared ferrous scrap into shorter sections.
The ability to cut a specific material depends on its cross-section, thickness, grade, hardness and position inside the cutting chamber.
6. Automatic Cutting Cycle
After each shearing stroke, the blade returns to its open position and the feeding system advances the remaining material. The machine can repeat the cycle according to the selected operating mode.
7. Material Discharge
Cut scrap is discharged below or behind the machine and collected directly or transferred by conveyor. The processed material can then be transported, sorted, baled or prepared for furnace feeding.
