Hydraulic Scrap Shear with 160-Ton Material Holding for Stable Heavy Steel Cutting

SEO Title: Hydraulic Scrap Shear with 160-Ton Material Holding System
Meta Description: The Q91Y-630W uses dual hydraulic holding cylinders with approximately 160 tons of total force to stabilize irregular steel scrap before shearing.

Why Material Holding Matters in Scrap Cutting

Heavy steel scrap rarely enters a shear in a perfectly flat or uniform condition. Plate remnants may overlap, structural sections may twist, and mixed scrap can shift when hydraulic force is applied.

The Q91Y-630W hydraulic scrap shear addresses this problem with two dedicated material-holding cylinders. Each cylinder provides approximately 80 tons of force, giving the system a combined holding force of about 160 tons.

The holding cylinders press the material before the main cutting movement begins. This helps keep loose or irregular scrap in a more controlled position inside the cutting chamber.

Dual Holding-Cylinder Configuration

The material-holding system includes:

The two-cylinder arrangement distributes holding force across the loaded material rather than relying on a single pressing point.

Materials That Benefit from Hydraulic Holding

The system is especially useful for:

• Stacked plate offcuts
• Bent structural steel
• Mixed production scrap
• Curved or twisted sections
• Long bars placed in groups
• Irregular demolition steel
• Scrap that does not lie flat

The holding device does not eliminate the need for correct loading. Materials must still be positioned inside the approved cutting area and must not exceed the confirmed cutting capacity.

Combined with a 1600mm Cutting Blade

After the material is held, the shearing cylinders drive a 1600mm-wide blade through the scrap.

The machine uses two 260-ton main shearing cylinders together with one 135-ton fast shearing cylinder. The supplied technical document calculates a combined force of 655 tons.

The holding and cutting systems therefore perform different functions:

• The holding cylinders stabilize the scrap.
• The shearing cylinders provide the cutting movement.
• The rear pusher controls material feeding.
• The length-control system determines the approximate advance distance.

Reference Cutting Sizes

For steel with tensile strength not exceeding 450MPa, the document lists:

• Round steel: Ø130mm
• Square steel: 120 × 120mm
• Steel plate: 60 × 600mm

The actual result depends on material strength, cross-sectional shape, number of pieces, blade condition, and loading position.

Applications

This configuration is suitable for recycling plants where irregular scrap movement can affect cutting consistency.

Typical users include:

• Heavy scrap yards
• Steel fabrication plants
• Steel mills
• Foundries
• Structural demolition processors
• Industrial metal recovery facilities

Selecting the Correct Holding and Shearing System

Customers should provide more than the daily scrap tonnage. Important selection information includes:

• Material photos
• Maximum cross-section
• Steel grade
• Solid or hollow structure
• Number of pieces loaded together
• Maximum material length
• Required final cut length

The Q91Y-630W combines approximately 160 tons of material-holding force with a 655-ton documented shearing configuration, making it suitable for controlled processing of heavy and irregular ferrous scrap within the specified material limits.
