• HNC10:​ The compact powerhouse, engineered for 1.5 to 3-ton​ mini excavators. Ideal for light demolition, interior stripping, and precise material handling in confined spaces.
• HNC30:​ The versatile performer, optimized for 2.5 to 5-ton​ excavators. Balances formidable power with agility, making it the go-to choice for general demolition, scrap processing, and utility work.
• HNC50:​ The heavy-duty specialist, built for 4.5 to 7-ton​ carriers. Delivers maximum cutting force and durability for the toughest industrial demolition, bridge deconstruction, and high-volume scrap yard applications.

Parameter

• Premium Steel Construction:​ All models utilize high-tensile, abrasion-resistant steel​ for the main body, arms, and jaws. This ensures exceptional durability against shock loads and wear from rebar and metal.
• Optimized Jaw Geometry:​ Each model’s jaw profile is computer-optimized for its weight class, creating an ideal crushing angle and shear point​ to maximize force transmission and material grip.
• Replaceable Serrated Teeth/Cutters:​ The cutting edges feature hardened, serrated, and replaceable teeth. This design provides superior bite, prevents material slippage, and allows for easy maintenance, drastically extending the shear’s service life.
• Heavy-Duty Twin Cylinders:​ Dual synchronized hydraulic cylinders are the core of the shearing power, providing smooth, powerful, and consistent clamping force to slice through the toughest materials.
• Reinforced Pivot Points with Hardened Bushings:​ Precision-machined pins and hardened steel bushings​ at all pivot points minimize friction, reduce wear, and eliminate unwanted play for reliable, long-term operation.
• Universal Mounting Bracket:​ Designed for quick and secure attachment to a wide range of excavator quick couplers within the specified weight range, minimizing machine downtime.

4. Engineering Excellence: Design, Technology & Working Principle

• Force-Optimized Linkage:​ The geometry of each model’s arm is calculated to provide the optimal balance between jaw opening width and closing force for its intended carrier size.
• Efficient Hydraulic Design:​ The cylinders and flow paths are engineered to deliver powerful performance within standard auxiliary hydraulic system parameters, ensuring compatibility and avoiding the need for costly system upgrades.
• Ruggedized Seal Kits:​ High-quality hydraulic seals are employed to withstand high pressure and contamination, ensuring long-term reliability and preventing fluid leaks in dusty, demanding environments.

5. In-Depth Application Scenarios: Transforming Challenges into Efficiency

• HNC10:​ Perfect for interior demolition, cutting lightweight steel studs, rebar in slabs, and concrete blocks. Its compact size allows for work in tight spaces like basements and multi-story buildings.
• HNC30:​ The ideal all-rounder for house demolition, commercial strip-outs, and cutting standard structural beams, columns, and reinforced concrete walls.
• HNC50:​ Tackles heavy industrial structures, bridges, and high-rise support elements​ with ease, shearing thick rebar and large structural sections.

• HNC10:​ Excellent for preliminary dismantling of small vehicles​ (cars, vans) and sorting non-ferrous materials in a controlled manner.
• HNC30:​ The star of auto recycling yards. Efficiently processes cars, SUVs, and light trucks, cutting frames, engines, and body panels for clean material separation.
• HNC50:​ Handles heavy trucks, buses, and industrial machinery, capable of shearing through axles, chassis rails, and dense engine blocks to maximize metal recovery.

• HNC30/HNC50:​ These models are indispensable for factory tear-downs. They provide cold-cutting power to shear through process piping, steel I-beams, storage tanks, conveyor systems, and heavy machinery frames​ safely and efficiently, without the fire risk of torches.

• All Models:​ Provide crucial capabilities for disaster relief and public works. They can quickly clear earthquake debris, cut through collapsed bridge sections, remove twisted guardrails, and dismantle unsafe structures. Their precision allows for safer work in unstable environments compared to indiscriminate methods.

• HNC10/HNC30:​ Highly effective for processing timber waste, pallets, and demolition lumber. They reduce volume on-site, saving on transportation and disposal costs. Their ability to handle mixed waste (wood with embedded metal) makes them ideal for C&D waste sorting and recycling facilities.
