Explore our precision-engineered heavy equipment attachments, manufactured to meet the most demanding demolition and structural dismantling specifications globally.
In high-density urban demolition and heavy-industrial metal reclamation, structural integrity and cutting kinetics dictate project margins. As global tier-1 contractors demand higher efficiency, the shift from single-cylinder cutting jaws to synchronized double-cylinder demolition shears has accelerated.
Unlike standard single-cylinder shears that exert asymmetrical force profiles during steel cutting, double cylinder demolition shears utilize synchronized dual-piston configurations. This technology delivers a symmetrical, balanced jaw alignment that completely eliminates the twisting forces commonly transferred back to the excavator boom. By dividing hydraulic pressure uniformly between two dedicated cylinders, operators experience up to 35% higher structural shearing yield strengths without increasing excavator fuel usage.
Engineered primarily for crushing reinforced concrete and slicing thick-gauge alloy steel (such as H-beams, channel steel, and rebar structures), these robust hydraulic attachments are fabricated using high-yield structural steel. Standard components feature custom speed-valves that dynamically bypass low-pressure resistance, speeding up jaw open/close times by 20% and driving down operational cycle durations in the field.
Dynamic Jaw Penetration: Dual-point contact reduces slippage, giving these shears unmatched ability to grip round structural pillars and massive metal profiles without shifting.
Structural Stress Analysis: Heavy excavation attachments demand precision metallurgy. Hardox 450/500 equivalent abrasion-resistant jaws ensure minimal shear deformation even under peak pressure cycles exceeding 350 bar.

Find authoritative, practical answers to common questions about double cylinder demolition shears, installation, and performance optimization.
Double cylinder shears utilize two synchronized hydraulic cylinders to deliver balanced, symmetrical force. This design prevents twisting stresses from transferring to the excavator boom, whereas single cylinder models exert lateral torque that can accelerate pin and boom bushing wear. Additionally, dual cylinder configurations provide higher structural crushing capacity when working on concrete pillars and thick metal frames.
The structural frames are constructed using high-yield structural steel to ensure longevity. The cutting jaws are equipped with wear-resistant, high-hardness alloy steel blades (equivalent to Hardox 500) that maintain clean shearing performance and offer high chip resistance under extreme structural cutting loads.
Yes, rotation speeds can be fine-tuned via the hydraulic flow regulators on your excavator, while the cutting force is dynamically managed by our built-in speed-valve assembly. This valve automatically balances speed and high pressure based on material resistance, maximizing both productivity and efficiency.
The shear requires a dual-acting auxiliary hydraulic circuit for jaw open/close functions, along with a secondary low-flow circuit if 360-degree rotation is equipped. Operating pressures generally range between 320 to 350 bar. We supply complete pin-on adapters or quick-coupler brackets tailored to fit your specific excavator's dimensions.
Key maintenance includes daily greasing of rotation bearings and main jaw pins, regular checks of hydraulic seal integrity, and periodic adjustment or replacement of the cutting blades. Reversing the multi-edged blades regularly helps maintain consistent cutting performance and minimizes wear on the jaw seats.
Our products undergo comprehensive quality management inspections and hold international quality system and machinery compliance approvals.
