Technical Specifications to Verify

Verifying the technical specifications of a rotating hydraulic demolition shear is paramount to ensuring operational efficiency and longevity. The cutting force, which can range from 155 tons to 1376 tons depending on the model, is a primary indicator of the shear’s capability to process dense materials. Buyers should confirm the driving pressure requirements, typically observed in the range of 320-350 kgf/cm², to ensure their excavator’s hydraulic system can support the attachment’s demands. Additionally, the cycle time, often cited around 15 seconds, provides insight into the speed of operations, which is crucial for high-volume recycling facilities. It is essential to verify that the hydraulic system’s flow and pressure ratings match the shear’s requirements to prevent performance degradation or hydraulic system damage.

The structural dimensions and material compatibility specifications must also be rigorously checked against the buyer’s operational needs. The maximum opening width, whether 450 mm, 565 mm, or 820 mm, dictates the largest cross-section of material that can be processed in a single cut. Buyers should also consider the cutting depth and the specific types of materials the shear is designed to handle, such as steel rods up to 100 mm in diameter or angle iron with dimensions of 250*25 mm. Furthermore, the rotation mechanism, whether hydraulic or manual, and its range of motion, typically 360 degrees, should be confirmed to ensure it meets the flexibility requirements of the job site. Understanding these technical details helps in selecting a shear that not only fits the excavator but also optimizes the material processing workflow.
