Q43W-4000A 4000 KN Horizontal Scrap Shear With 1400 × 450 Mm Discharge Opening

The Q43W-4000A horizontal scrap shear is a heavy-duty hydraulic machine designed for the compression, feeding and cutting of ferrous scrap. It is also commonly described as a container metal shear, box shear or horizontal scrap shear.

The machine is suitable for scrap yards, steel mill charge-preparation areas, metal fabrication plants, dismantling facilities and industrial recycling centers.

It provides a nominal cutting force of 4000 kN, approximately 400 tons, and uses a 1400 mm shear blade. Scrap is compressed and pushed toward a 1400 × 450 mm discharge opening, where the hydraulic blade cuts the material into more manageable lengths.

Compared with manual flame cutting, the Q43W-4000A container metal shear uses cold hydraulic cutting and does not require oxygen and fuel gas for every cutting cycle.

The reference cutting speed is approximately 2–3 strokes per minute. This makes the machine suitable for processing ordinary carbon steel scrap, plate offcuts, rebar, steel sections, pipe and selected mixed ferrous scrap.

The detailed specification lists a hydraulic-system pressure of 25 MPa, motor power of 74 kW, an air-cooled hydraulic oil system and button control. The machine weighs approximately 21,500 kg, providing a heavy and stable structure for industrial scrap processing.

Scrap yards rarely receive uniform material. Incoming loads may contain demolition rebar, plate offcuts, steel pipe, structural sections, machinery scrap and light sheet metal.

Without suitable processing equipment, customers often experience several operational problems.

Plate offcuts, rebar, pipe and structural steel overlap and create large empty spaces inside the scrap pile. The yard reaches its volume limit before storing an economical metal weight.

Long rebar, sections and pipe are difficult to load safely and may not fit the charging requirements of a steel mill.

Flame cutting consumes oxygen and fuel gas and requires skilled labor. It also introduces smoke, heat, sparks and variable production.

Unprocessed scrap has widely varying lengths and shapes, making grab loading, stock management and furnace charging less predictable.

Moving scrap between sorting, compression and cutting areas requires more crane time and increases operating costs.

The Q43W-4000A horizontal scrap shear combines loading, compression, hydraulic pushing and shearing in one processing system.

After scrap is loaded into the chamber, hydraulic mechanisms compress and organize the material. The pusher then moves the compacted scrap toward the 1400 mm cutting blade.

This process helps customers:

• Reduce the space occupied by loose scrap;
• Cut long material into transportable lengths;
• Reduce dependence on manual gas cutting;
• Improve truck and container loading;
• Produce more regular furnace charge;
• Reduce intermediate material transfer;
• Create a more stable daily processing rhythm;
• Improve scrap-yard organization and stock control.

For businesses mainly handling light steel scrap, plate offcuts, ordinary sections and mixed ferrous material, a 400 ton container shear can provide a practical balance between investment and processing capability.

The short parameter list states 37 kW, while the detailed specification states 74 kW. The final motor power should be confirmed in the approved technical document before publication or quotation.

Actual capacity and cutting performance depend on material grade, cross-section, bulk density, feeding efficiency and required cut length.

The approximately 400 ton cutting force supports the processing of various ordinary carbon-steel materials in medium and large recycling applications.

The wide blade covers a substantial cutting area and is suitable for plate offcuts, bundles of rebar, steel sections and mixed scrap.

The controlled outlet helps guide compressed scrap into the cutting zone and improves feeding stability.

Scrap is compressed before cutting, reducing uncontrolled movement near the blade.

The cutting rhythm supports continuous industrial production. Actual hourly tonnage depends on the feed material and operating method.

The hydraulic power unit provides energy for compression, material pushing and cutting functions.

Air cooling avoids the need for a separate cooling-water circuit and simplifies installation at sites with limited water access.

The main machine movements are controlled through push buttons, offering a straightforward operating method.

The heavy machine frame helps maintain stability during high-force compression and cutting.

The machine can process a reasonable range of plate, rebar, pipe, structural sections, stamping waste and mixed ferrous scrap.

The Q43W-4000A horizontal container scrap shear is suitable for:

• Scrap metal recycling yards;
• Steel-mill scrap preparation plants;
• Resource-recovery centers;
• Structural steel factories;
• Metal fabrication and stamping plants;
• Vehicle and machinery dismantling centers;
• Port scrap-transfer stations;
• Ship-repair and dismantling yards;
• Demolition scrap processors;
• Foundries and metal-smelting facilities.

Typical materials include:

• Mild-steel plate offcuts;
• Light sheet and stamping skeletons;
• Scrap rebar and round bars;
• Angle iron, channel steel and I-beams;
• Ordinary steel pipe and hollow sections;
• Dismantled vehicle body steel;
• Machinery frames and structures;
• Steel wire and wire-processing scrap;
• Compressible mixed ferrous scrap.

High-strength alloy steel, spring steel, railway steel, hardened shafts, large cast-iron pieces, sealed containers and oversized thick plate require separate technical evaluation.

1. Scrap Sorting and Safety Inspection

   The operator checks material type and dimensions and removes sealed containers, flammable items, stones and hazardous contamination.

2. Loading the Chamber

   A grab crane, overhead crane or other mechanical loader places scrap into the horizontal chamber.

3. Hydraulic Compression

   The compression system organizes and compacts loose scrap into a more stable feed form.

4. Material Pushing

   The hydraulic pusher moves the compressed material toward the discharge opening and shear area.

5. Hydraulic Cutting

   The 4000 kN shear mechanism drives the 1400 mm blade through the scrap.

6. Repeated Feeding and Cutting

   The pushing and cutting sequence repeats until the loaded material has been processed.

7. Product Discharge

   The cut scrap exits the machine and can be transferred by grab or conveyor for storage, loading or furnace charging.

Light scrap requires sufficient chamber and compression capacity. Plate, rebar and structural sections require greater attention to cutting force and blade length.

Provide plate thickness and width, round-bar diameter, structural-section dimensions and the number of pieces to be cut at one time.

Daily tonnage alone is not sufficient. The number of operating hours determines the required hourly capacity.

Shorter finished lengths require more cutting cycles and may reduce actual tonnage output.

Consistent output requires stable loading. Industrial yards normally use a grab crane or overhead crane.

The customer should provide voltage, frequency, phase and transformer capacity. The detailed specification lists 74 kW motor power.

The standard system uses air cooling. High-temperature or long-duty applications may require additional cooling.

For furnace charging, confirm furnace-opening dimensions and desired charge length. For transport, confirm truck and container requirements.

The selected machine should have reasonable reserve capacity rather than operate continuously at its maximum limit.

It is suitable for ordinary carbon-steel plate, rebar, pipe, angle iron, channels, I-beams, stamping scrap and selected mixed ferrous material. Final suitability depends on material grade and cross-section.

A nominal force of 4000 kN is approximately equivalent to 400 tons. Actual cutting performance also depends on blade condition, material strength and the number of pieces cut together.

The supplied specification does not state a fixed tonnage per hour. Actual capacity depends on scrap density, dimensions, loading efficiency and cutting length.

Air cooling is suitable for normal ambient temperatures and reasonable duty cycles. Hot climates or continuous heavy-duty use may require enhanced air cooling or water cooling.

These materials should not be evaluated using ordinary mild-steel data. Their grade and dimensions must be reviewed separately by an engineer.
