Hydraulic Alligator Shear

The alligator shear, also known as a crocodile cutter, consists of a shearing cylinder, shearing blades, a sliding block pressure blade, a lower blade holder, and a pressure cylinder. During the shearing operation, the hydraulic pump station operates. The power source supplies oil to the pressure cylinder, pushing the sliding block pressure blade to press against the lower blade holder, thus securing the material. Then, the hydraulic pump station supplies oil to the shearing cylinder, driving the shearing blades downwards to complete the shearing action. After shearing, the hydraulic pump station, through the continuous return flow of hydraulic oil, drives the shearing cylinder and pressure cylinder to complete the return stroke. Alligator shears are suitable for scrap metal recycling plants, scrap car dismantling yards, and the smelting and casting industry.

The hydraulic alligator shear is an indispensable heavy-duty pre-processing equipment in the metal recycling and processing industry. It is named for its unique "alligator mouth" shearing action and is specifically designed to efficiently and safely shear large, heavy, and irregular scrap metal (such as reinforcing bars, structural steel, steel plate scraps, scrapped components, and scrap car beams) into sized materials that are easy for subsequent processing and smelting. This equipment is a core component for achieving volume reduction, density increase, and added value enhancement in scrap steel. It is mainly used in the waste recycling and processing industry of small and medium-sized enterprises for cold shearing and cutting of scrap metal of various cross-sectional shapes in steel plants, such as round steel, square steel, channel steel, angle steel, I-beams, steel plates, and steel pipes.

Advantages of the Alligator Shear

(1) Hydraulically driven, easy to operate and maintain.

(2) The shearing force of the working blade has 9 levels, ranging from 63 tons to 500 tons.

(3) Compared with mechanical transmission shears, it has the advantages of small size, light weight, low inertia, low noise, stable operation, convenient and flexible operation, and large shearing cross-section. It also has the advantages of convenient shearing adjustment, safe operation, and easy overload protection.

Application Scenarios

Scrap metal recycling and processing centers: Primary shearing of various recycled heavy scrap steel.

Scrap car dismantling plants: Shearing strong components such as car beams, frames, and body pillars.

Steel structure manufacturing plants: Processing heavy steel plates and steel scrap generated during production. Ship dismantling and casting industry: Pre-processing large metal components to prepare qualified furnace feed.

Large-scale engineering construction projects: On-site processing of steel reinforcement and steel structure waste generated during construction.
