HX-320 Hydraulic Shear for 24+ tons excavator.In scrap metal processing, shipbreaking, and large‑scale steel structure demolition, cutting efficiency directly determines profitability. Every second saved in cycle time and every reliable cycle contributes real returns to equipment owners.
To meet the demands of 240+ class excavator users for higher productivity and longer service life, we are proud to introduce the RedStar Model 320 Hydraulic Shear – a heavy‑duty attachment built for high‑output applications.
Ultra‑Fast Cycle: 5–6 Seconds Open & Close
Cycle speed is the first measure of hydraulic shear productivity. With optimized cylinder bore and oil passage design, when matched to the hydraulic flow of a 240+ class excavator, the Model 320 achieves a full open‑close cycle in just 5–6 seconds. Compared to conventional shears in its class, this speed translates into more cuts per hour and significantly higher tonnage processed per shift.
Efficiency Gain: 10%+ Improvement Over Model 32090
Using our previously popular Model 32090 as a benchmark, the Model 320 delivers a verified productivity increase of more than 10% under real‑world conditions. This gain comes from three factors:
Faster cycle time
Improved cutting geometry that reduces jamming
Higher cutting force transmission efficiency – more tonnage output for the same hydraulic flow
For heavy‑duty applications running 8–10 hours per day, a 10% efficiency gain can mean hundreds of extra tons of scrap processed each month – significantly shortening the payback period.
One‑Piece Steel Plate + 80mm Reinforced Arms
Structural strength is the foundation for handling high‑intensity, high‑impact cutting. The Model 320’s housing is machined from a single steel plate – no welded seams, eliminating weak points.
Arm thickness: 80mm – well above industry averages, effectively resisting the extreme bending moments generated when cutting heavy H‑beams and thick‑walled pipe.
Steel grade: Xingcheng Wear‑Resistant 450 (HB450 equivalent), combining high hardness with good toughness – ideal for cutting scrap with impurities or high‑strength materials.
Double‑Sided Stiffeners: Worry‑Free & Maintenance‑Friendly
Lateral forces during cutting can cause housing deformation or uneven blade wear over time. The Model 320 features double‑sided stiffeners (reinforcing ribs) on both shear arms, dramatically improving torsional rigidity.
Real‑world benefits of this design:
Resists housing deformation – extends structural life
Maintains uniform blade clearance – reduces blade misalignment and jamming
Lowers maintenance frequency – users only need routine blade changes, not frequent re‑alignment or weld repairs
“Worry‑free” comes from reliable construction; “maintenance‑friendly” comes from low failure rates – this is the promise the Model 320 delivers to every operator.
Recommended Excavator & Typical Applications
Recommended excavator class: 240 and above (well matched to 25–35 ton excavators; verify hydraulic flow)
Typical applications:
Large scrap yards (dismantling heavy trucks, buses, construction machinery)
Shipbreaking (cutting hull plates, frames, piping)
Full steel structure demolition (cutting H‑beams, I‑beams, channels)
