Hydraulic shears for excavator can be roughly divided into mechanical type and hydraulic type, among which hydraulic type can be divided into fixed type and rotary type, while rotary hydraulic shears can be divided into single cylinder and double cylinder.

1. Mechanical hydraulic shear
The mechanical hydraulic shear is that the bucket arm cylinder of the excavator acts on the connecting rod rocker arm to expand and contract, and the power is applied to the upper cutting edge, and the lower cutting edge is fixed on the stick, so that the cutting operation can be realized without using other auxiliary cylinders and hydraulic pressure. system.
Features: cheap price, compact structure, simple and convenient installation; the disadvantage is that the shearing force is not as large as the hydraulic type.
Application: Light and thin steel structure, shearing treatment of scrap steel, can cut steel bars, pipes, cans and other iron materials.
2. Stationary hydraulic shear
The manufacturer of hydraulic shears for excavator tells you that the fixed hydraulic shears have their own hydraulic cylinders, which use the powerful thrust of the cylinders for shearing.
Features: The shearing force is greater than that of mechanical hydraulic shears; the disadvantage is that it cannot be rotated, and it is inconvenient to find the position when removing or shearing steel structures.
Application: Dismantling of scrapped vehicles, processing of scrap metals such as scrap steel.
3. Rotary hydraulic shear
The manufacturer of hydraulic shears for excavator tells you that rotary hydraulic shears are divided into two types: single cylinder and double cylinder. The equipment can rotate 360 ​​degrees, which has a wider application range and is more convenient to use.
Features: The cylinder of the single-cylinder hydraulic shear is thicker, and the shear force is greater than that of the double-cylinder hydraulic shear. It is the largest shear force among excavator hydraulic shears, and its performance is 20% higher than that of ordinary hydraulic shears.
Application: The manufacturer of hydraulic shears for excavator tells you that single-cylinder hydraulic shears can be installed on excavators to dismantle and process scrapped vehicles, scrap steel and scrap metal, and can also be used for crushing and demolishing reinforced concrete in buildings, cutting branches, etc. Double-cylinder hydraulic shears can be equipped with extended arms for mechanized demolition of buildings, shearing of steel bars, etc.
