Hydraulic shears - the "steel scissors" of excavators
Hydraulic shears are an attachment installed on an excavator and are mainly used to cut various metal materials, such as steel plates, steel bars, etc. Its working principle is to use the powerful force generated by the hydraulic cylinder to drive the shear body to close, thereby applying shear force to the material to achieve the purpose of cutting.
How hydraulic shears work
Hydraulic system provides power: The excavator's hydraulic system provides power source for the hydraulic shear, generating huge pressure.
Hydraulic cylinder drives the shear body: Hydraulic oil enters the hydraulic cylinder through the hydraulic pipeline, pushes the piston to move, and drives the shear body to close.
Blade cutting material: When the blade is closed, its sharp edge exerts shearing force on the material, causing the material to break.
As an efficient and convenient cutting tool, hydraulic shears play an increasingly important role in engineering construction. Through the working principles, classification, characteristics and applications of hydraulic shears, you can better select and use hydraulic shears and improve work efficiency.
