Hydraulic Scrap Gantry Shear | Heavy Duty Scrap Metal Cutting Machine

Hydraulic scrap gantry shear is a heavy-duty stationary shearing machine widely used in scrap metal recycling yards, steel mills, demolition waste processing bases and vehicle dismantling plants. Also known as scrap gantry guillotine shear, it is designed to cut bulky, thick and oversized scrap metal into uniform, transportable sizes for melting, reprocessing and trade. Unlike small alligator shears, gantry shear features a portal gantry frame, large feeding chamber and powerful hydraulic driving system, supporting crane feeding for long steel beams, ship plates, railway rails and heavy HMS scrap.

A scrap gantry shear works on hydraulic compression and vertical downward shearing. Bulk scrap metal is loaded into the large feed box by overhead crane or loader. The compression ram first squeezes loose and irregular scrap to stabilize the material, then the heavy blade moves down with tons of shearing force to cut the metal into short pieces. Most models adopt PLC automatic control system, supporting manual, semi-auto and continuous circulation modes. The whole cycle runs steadily with low impact, reducing labor input and improving continuous production capacity for high-volume recycling operations.

Our scrap gantry shear brings clear operational benefits for scrap processors. First, the robust welded gantry frame undergoes stress relief treatment, which keeps stable performance under long-time heavy load and extends service life. Second, the high-hardness alloy shear blade is replaceable, easy to maintain and ensures clean cutting edges without burrs. Third, hydraulic power units adopt well-known brand components, with low failure rate and convenient maintenance. Customization is available: feed box size, blade length, shearing tonnage and remote control can be adjusted according to clients’ site conditions and material types. It can handle carbon steel, stainless steel, aluminum scrap, copper profiles and mixed heavy scrap.

Scrap gantry shear serves multiple industrial scenarios. Scrap recycling centers use it to process mixed heavy scrap for standard furnace feeding size. Steel mills apply it for pretreatment of waste steel raw materials. Vehicle dismantling factories cut car frames and chassis scrap. Demolition yards process I-beams, steel pipes and thick steel plates. This machine is a core piece in scrap metal pretreatment lines and often matched with scrap baler, conveyor and metal sorting equipment to build a complete scrap processing system.

When selecting a scrap gantry shear, buyers should evaluate several key parameters. Confirm the maximum scrap size and thickness you process daily, then choose matched shearing force, usually ranging from 400 ton to 2000 ton. Calculate required hourly output to avoid bottlenecks. Check available feeding method: crane feeding is standard for gantry shear, so your workshop needs enough overhead crane space. Site power supply, foundation layout and local maintenance support also matter. You can send us scrap photos, expected capacity and workshop dimension, we provide tailored gantry shear solution and layout drawing.

FAQ

Q: What is the difference between gantry shear and alligator shear?
A: Scrap gantry shear is for heavy, bulky scrap and high continuous output, with large feed box and compression function. Alligator shear is smaller swing-jaw type, fit for small to medium thin scrap and lower throughput.
Q: Can scrap gantry shear process car body scrap?A: Yes, it can cut dismantled car frames and chassis after rough pre-treatment.
Q: Is the gantry shear customizable?
A: Yes, we customize feed box, blade length, hydraulic system and control mode for scrap recycling plants.
