Hydraulic Shears For Excavator

Hydraulic hawkbill shears are a front-end attachment for use with excavators. lt gets its name from its shape, which resembles an eagle's beak. Hydraulic hawkbill shears provide power through the hydraulic system to realize the movement of the cutter head and the opening and closing of the clamping groove. When the operating handle or control valve is activated, hydraulic oil will enter the cylinder and push the piston to move, thereby driving the movement of the cutter head and clamping groove. By adjusting the position of the control valve, different working modes of the hawkbill shears can be realized, such as cutting, clamping, lifting, etc. Therefore, the hydraulic hawkbill shear is a practical and efficient mobile scrap steel dismantling machine and scrap car dismantling equipment.

product detail

Product Description

Upper knife seat

It is made of welded steel plate, which has the characteristics of high strength, high precision and high efficiency. The design flexibility of the movable upper knife seat, the reduction of wear and pressure, the improvement of shearing efficiency, the ease of maintenance and replacement, and the improvement of equipment stability, etc. It can greatly improve the efficiency and reliability of the hawkbill shears during use, so as to better complete the cutting and crushing work.

Lower knife seat

Using high-strength steel processing, radian and slope design, can better clamp and fix the sheared material. The lower blade can turn over 4 edge faces to reduce the cost of use.

Case

It is processed by high-strength alloy steel, which has strong wear resistance and corrosion resistance, and can withstand high pressure and stability.

Rotary motor

Equipped with a rotary motor to achieve two-way 360° rotation, the control is simpler and more convenient.

Reduction gearbox

It is equipped with a reduction gear to achieve smooth adjustment of the rotation, avoiding damage to the equipment caused by hydraulic shock.

Booster valve

Combined with speed-increasing valve to realize precise control of hydraulic oil flow and improve the working efficiency and precision of hawkbill shears.

Tailstock

The rotating rear tailstock can be more stable during operation, reducing shaking or imbalance caused by unbalanced digging force, and improving the accuracy and safety of operation. The rotating rear tailstock is made of materials with good wear resistance, which can withstand high-intensity friction and wear during excavation operations, prolonging the service life.
