What Is a Metal Gantry Shear?
A metal gantry shear-also known as a gantry guillotine shear or hydraulic scrap metal shear-is a heavy-duty industrial cutting machine designed for processing large-volume scrap metal. Unlike traditional alligator shears or flame cutting methods, the gantry shear utilizes a vertical hydraulic cutting principle to slice through thick steel plates, structural beams, car bodies, and mixed scrap metal with exceptional speed and precision.
The Industrial Metal Cutting machine features an integral welded gantry frame structure that delivers superior rigidity and stability under extreme loads-. Hydraulically driven, it offers advantages over mechanical transmission shears including compact size, light weight, low motion inertia, quiet operation, smooth movement, flexible control, and large shear cross-section.

FAQ
1: What materials can a gantry shear process?
A: Gantry shears handle a wide range of ferrous scrap: carbon steel, stainless steel, steel plates, round bars, square bars, structural beams, railroad tracks, vehicle frames, and mixed HMS scrap . Some models also process aluminum and non-ferrous metals.
2: How does a gantry shear differ from an alligator shear or guillotine shear?
A: Gantry shears feature a portal-frame design with a movable crossbeam, providing superior stability and force for cutting thick, bulky materials . Alligator shears are typically smaller and suited for lighter scrap, while guillotine shears are optimized for plate cutting rather than bulky scrap processing .
3: What is the typical shear cycle time?
A: Most industrial gantry shears operate at 3–4 cycles per minute, depending on material thickness and type . Larger models like the Q43L-12500B operate at 2–3 cycles per minute due to the extreme cutting force involved .
4: How much floor space is required?
A: Large gantry shears can exceed 20 meters in length and weigh over 100 tons . For example, the Q43L-12500B measures approximately 22,500 × 8,500 × 6,000 mm and weighs 140 tons . Custom configurations are available for space-constrained facilities.
5: What are the maintenance requirements?
A: Regular inspection and lubrication of hydraulic systems, blade alignment checks, and timely blade replacement are essential . High-quality units are designed for low-maintenance operation, with easy access to service points and modular components for quick repairs .
6: Can the machine be customized for my specific scrap type?
Yes. Manufacturers offer custom feed box dimensions, blade configurations, hydraulic pressure adjustments, and feeding systems to optimize performance for specific scrap streams .
7: What safety features are included?
A: Standard safety features include emergency stop buttons, safety light curtains, guardrails, overload protection, and automated operation modes that minimize operator exposure .
8: What is the delivery time for a gantry shear?
A: Delivery times vary by manufacturer and customization level. Standard units may ship within 30–60 days; custom-built systems may require 90–120 days. Always request a confirmed delivery schedule.
