Features & Benefits

Reinforced, thickened shear arms
Anti-twist blade protection; the complete unit offers high strength, good rigidity and resistance to deformation
Replaceable, adjustable blade structure
Prevents blade misalignment and twist; the blades self-reset and always stay in optimal cutting condition
Patented pressure-retention lubrication system
Short periods without greasing will not seriously damage pivot components — more forgiving operation and lower maintenance costs
Exclusive H-frame tie-rod design
A complete open-close cycle takes just 2 seconds — fast, time-saving shearing
Bucket-pin disc design
Non-rotating pin design reinforces load distribution in the main frame plates and extends equipment durability
Optimized leverage points on the H-frame
High torque transfer with maximum effective force-conversion range
Blades made of ultra-wear-resistant material
Anti-breakage blade design — blades wear longer and last longer
Patented corner-strap tie-arm mount
Lets the grapple align perfectly with any excavator stick angle, avoiding impact fatigue and wear on the stick
Upper and lower shear arms use Xingcheng NM450 wear plate; other structural parts use Q460C high-strength steel
High overall strength and rigidity with excellent deformation resistance, extending equipment durability
