Technical DetailsPortugal’s industrial infrastructure is experiencing a pivotal structural shift driven by modern European Union climate policies and smart regional infrastructure development plans. From the deepwater expansions at the Port of Sines to urban renewal projects across Lisbon and Porto, Portuguese heavy demolition contractors and environmental recycling operators are continuously seeking specialized ways to maximize material recovery yields and reduce downtime.
Under the European Green Deal and Portugal’s own circular economy plans, the processing of scrap metals, concrete fragments, and industrial waste has shifted from basic landfilling to advanced, high-efficiency material recovery. Hydraulic shears mounted on 20 to 50-tonne excavators are now the baseline requirement for standard operations. These hydraulic attachments must perform flawlessly under challenging conditions, such as high salinity in coastal dock rebuilding and intense heat cycles in regional scrap recycling centers.
Furthermore, local operators face strict noise and vibration regulations. Standard methods of blasting or drop-ball shattering are strictly prohibited in municipal areas. This makes highly efficient hydraulic rock breakers and specialized scrap metal shears crucial for contractors striving to remain compliant while maximizing daily tonnage output.
Integrating advanced heavy machinery into Portuguese demolition fleets ensures maximum uptime. Our design methodology focuses on optimal force curves, premium grade wear plates, and accessible lubrication channels, giving operations an unmatched competitive edge.
Initially established in December 2016 and expanded with a registered capital of 20 million yuan, Yantai Huida has evolved into a global powerhouse in the research, development, and high-precision manufacturing of construction attachments and eco-friendly scrap-processing equipment.
Holding nearly 40 product patents, our core engineering philosophy centers on structural longevity and hydraulic efficiency. Every single attachment—from our high-yield Eagle Shears to heavy dual-cylinder scrap cutters—undergoes rigorous quality testing, backed by the ISO9001 Quality Management System.
When sourcing hydraulic attachments, modern procurement officers in Portugal analyze key variables: the cost-to-performance ratio, hydraulic cylinder reliability, and the availability of replacement wear blades. By sourcing directly from our state-of-the-art Chinese manufacturing plant, clients secure tier-1 quality without paying inflated dealer premiums.

Our shears utilize high-strength alloy steels, specifically Q460 for the main body structure and certified Hardox-equivalent plates for high-wear areas like the jaw housings and outer cutting arms. This combination provides excellent yield strength (resisting bending or cracking under high pressure) while keeping the overall attachment weight low to protect your excavator's boom assembly.
The speed regeneration valve dynamically manages hydraulic oil flow during the shear's jaw stroke. When the jaw meets little to no resistance, the valve recirculates return oil back to the piston chamber, speeding up the stroke. As soon as the blade contacts hard metal, the valve automatically shifts back to full pressure mode for maximum cutting force. This dynamic system can cut cycle times by 25% to 33%, allowing your operators to process more scrap tonnage per hour.
Our blades feature a reversible 4-way design, giving you four fresh cutting edges before the blade needs replacement. We recommend checking blade clearance daily and rotating the blades every 80 to 120 operational hours, depending on the hardness of the scrap being processed. Ensuring proper blade gap prevents metal jamming and protects the main pivot pins and hydraulic cylinders from offset stress.
Yes, all our excavator attachments are built under rigorous ISO9001 quality management guidelines. For European markets, including Portugal, we utilize low-noise silencing housings on our rock breakers and integrate advanced dual-lock safety mechanisms on our couplers to ensure full compliance with regional workplace safety and environmental regulations.
