Overview
Gantry Shear, also known as gantry shear machine, this type of gantry scissors is suitable for cutting and crushing all kinds of waste plates, bar materials, ferroalloy charges, special plates, ship plates, automobiles, metal pressing blocks, iron scraps and other scrap steel at one time so as to replace manual dismantling in order to reduce production costs to achieve better and convenient benefits. The 200-1800 tons gantry shear machine produced by our company adopts a new electro-hydraulic control system with the advantages of high automation level, stable work and outstanding pressure resistance. In the application of gantry shear machine, our company's products are packaged gantry shear machine and independent gantry frame for users to choose. Gantry shear machine is a kind of equipment suitable for heavy scrap cutting processing. Our company production of gantry shear tonnage in 200-1800 tons of conventional models shear material width in 600-2000mm for light steel, steel, steel plate, steel plate, steel, steel, scrap copper, scrap iron, light metal structural parts, stainless steel, metal block, automobile body, aluminum alloy, copper, iron, steel wire, automobile, metal block and so on For the crushing and processing of heavy waste and winding materials that cannot be handled by scrap crushing equipment, the working efficiency of this series of equipment can reach 3-6 times /min according to the model due to the new electro-hydraulic control system and enhanced cylinder. The application of the machine solves the problem of crushing and recycling of large heavy waste charge, and is widely used in rolling mills, metallurgical plants, scrap treatment and recovery units.

Structure Principle
1. Add a high-pressure filter to the hydraulic system. The hydraulic oil needs to pass through a high-pressure filter before entering the pipeline and hydraulic control valve. (High pressure filter comes with alarm)
2. Independent air cooling: This machine adopts a high air flow air cooling machine to control the oil temperature of the hydraulic oil within the normal range of use. At the same time, the air-cooled machine solves the problem of inconvenient water sources due to the occupied area of the water cooler.
3. PLC manual automatic control box. Can achieve manual and automatic replacement. Equipped with a remote control for remote start, stop, and automatic operation.
4. Pushing groove with pressure cover: It can achieve automatic feeding and simultaneously push the material along the pressure cover to the main cutting machine for cutting.
5. Special universal connection device at the front end of the cylinder rod. Effectively protect the cylinder rod from damage.

Product Features：
1. Adopting hydraulic transmission, low noise, complete functions, high production efficiency, optimized structural design, stable and reliable.
2. The sturdy open structure with integral welding can maintain sufficient rigidity of the body and provide convenient operating space.
3. The pressing stroke is generally controlled by a timer, pressure switch, position sensor, or the customer's own mold.
4. Suitable for sheet metal punching, bending, flanging, sheet metal stretching, precision punching, and cold extrusion of metal parts.
5. Adjustable pressing force, no overload generated, achieving pressure maintaining and delay requirements for each step during the pressing process.
6. The rebound height of the press mounted spindle can be adjusted within any travel range through a timer or position sensor.
7. Low oil pump displacement, low motor power, energy-saving, energy-saving.
8. Centralized button with three operations: manual, semi-automatic, and automatic.
9. The hydraulic system meter is built into the rack, with a clean, lightweight, and stable appearance.
10. Optional: Install photoelectric protection device, automatic oil lubrication device, oil temperature cooling constant temperature device.
