Heavy Duty Q43W-4000 Hydraulic Scrap Box Shear With 1400mm Blade For Scrap Processing

Heavy Duty Q43W-4000 Hydraulic Scrap Box Shear With 1400mm Blade For Scrap Processing

Product Overview

The Q43W-4000 box shear is a heavy-duty hydraulic scrap shear designed to compress and cut bulky metal waste into shorter, manageable pieces. With 4000 kN cutting force, a 1400 mm blade and an approximate cutting frequency of 2–3 cycles per minute, it provides an efficient solution for scrap yards, steel mills and metal recycling centers processing mixed ferrous scrap.

Unlike a traditional open-blade shear, this hydraulic box shear combines material loading, side compression, feeding and cutting in one integrated system. Loose and irregular scrap is loaded into the box, compressed into a controlled profile and gradually pushed toward the cutting head.

This enclosed processing method reduces the need for extensive manual sorting and pre-compression. It is particularly suitable for long, bulky or irregular scrap that is difficult to feed directly into a conventional alligator shear.

The Q43W-4000 can be equipped with PLC automatic control and remote operation, allowing the operator to supervise loading and cutting from a safer working position. Electrical voltage, feeding-box dimensions, cooling system and safety configuration can be customized for different countries and operating conditions.

Cause: Bulky Scrap Is Difficult to Store, Feed and Transport

Mixed steel scrap often contains thin plates, pipes, profiles, structural offcuts, vehicle-body parts and irregular production waste. These materials occupy considerable space and cannot be loaded efficiently into furnaces or downstream recycling equipment.

Common operating problems include:

• Long scrap pieces that cannot be transported or melted directly
• Irregular material that becomes tangled during feeding
• Excessive crane and excavator handling
• Unstable scrap piles in the working area
• Low container and truck loading efficiency
• Difficult furnace charging
• High labor requirements for material preparation

Using only manual gas cutting or small shearing equipment can result in slow production, inconsistent cut lengths and increased operating cost.

Solution: Combine Compression, Feeding and Cutting

The Q43W-4000 container shear solves these problems by processing scrap inside a reinforced loading box.

After loading, the hydraulic compression system presses bulky scrap into a more consistent profile. A hydraulic pusher then moves the compressed material toward the cutting head. The 4000 kN main shear cylinder drives the 1400 mm blade through the prepared scrap.

The working sequence can be repeated automatically until the material inside the box has been completely processed.

Key advantages include:

• 400 ton cutting force for mixed ferrous scrap
• Integrated compression and shearing structure
• Large loading area for bulky and irregular materials
• Reduced requirement for manual pre-cutting
• Adjustable feeding length for different cut sizes
• PLC-controlled working sequence
• Optional remote operation
• Stable processing of continuous scrap batches
• Compact cut material for easier storage and transportation
• Customizable electrical and hydraulic configurations

Specifications

The specifications may vary according to the selected loading box, hydraulic system, electrical standard and optional equipment. A heavy-duty configuration with higher installed power and machine weight can also be designed for demanding applications.

Application

The Q43W-4000 hydraulic scrap shear is suitable for processing medium and heavy volumes of ferrous metal waste in industrial recycling environments.

Scrap Metal Recycling Yards

The machine can process mixed steel scrap, sheet-metal waste, pipes, profiles and irregular structural offcuts collected from different sources.

Steel Mills and Foundries

Cut scrap can be prepared to more manageable dimensions for furnace charging, internal transport and material blending.

Vehicle Dismantling Facilities

Appropriately dismantled and drained vehicle-body panels, chassis sections and automotive metal parts can be compressed and cut before further recycling.

Metal Fabrication Plants

Long production offcuts, steel frames, rejected components and fabrication waste can be processed close to the production site.

Demolition Scrap Processing

Steel recovered from buildings, industrial structures and machinery dismantling can be reduced to transportable sizes after unsuitable materials have been removed.

Scrap Collection and Transfer Centers

The machine helps reduce the volume of bulky metal before the material is loaded into trucks, containers or rail wagons.

Typical materials include:

• Light and medium scrap steel
• Steel plates and sheet-metal offcuts
• Pipes and steel profiles
• Rebar and construction scrap
• Stamping and fabrication waste
• Dismantled automotive metal
• Machine frames and structural offcuts

Material thickness, maximum dimensions and composition should be evaluated before confirming the final machine configuration. Sealed cylinders, pressurized containers, explosive objects and hazardous materials must not be loaded into the shear.

How It Works

1. Scrap is inspected and unsuitable materials are removed.
2. An excavator or hydraulic grab loads the prepared scrap into the feeding box.
3. The hydraulic compression system closes and presses the loose material into a controlled profile.
4. The pusher moves the compressed scrap toward the shearing head.
5. The main hydraulic cylinder drives the blade downward and cuts the material.
6. The cut scrap falls into the designated collection or conveyor area.
7. The pusher advances the remaining material according to the preset cutting length.
8. The compression, feeding and cutting sequence continues until the loading box is empty.

PLC control coordinates the hydraulic movements and operating sequence. The operator can monitor the process and use manual control when adjustment or maintenance is required.

How To Choose

Confirm the Scrap Type

Provide photos or videos showing the material, maximum dimensions, wall thickness and approximate composition. Pipes, sheet metal, structural sections and mixed demolition scrap require different feeding and compression conditions.

Evaluate the Required Cutting Force

The Q43W-4000 provides 4000 kN shearing force. If the material includes very thick solid steel, large round bars or extremely heavy structural sections, a material test or higher-capacity shear may be necessary.

Check the Blade Length and Opening

The 1400 mm blade is suitable for a wide range of mixed scrap. Buyers should confirm that the largest material profile can enter the shear opening after compression.

Select the Loading Box

The box dimensions should match the available excavator, scrap volume and maximum material length. A longer or enlarged feeding box can reduce cutting preparation but requires more installation space.

Confirm the Required Automation

PLC automatic control is recommended for continuous production. Remote control allows the excavator operator or supervisor to manage important machine movements from a suitable position.

Review the Installation Site

Before production, confirm the concrete foundation, electrical supply, cable capacity, hydraulic-oil requirements, maintenance space and cut-material discharge area.

FAQ

1. What materials can the Q43W-4000 box shear process?

It is mainly used for steel plates, pipes, profiles, rebar, vehicle-body metal, structural offcuts and mixed ferrous scrap. The maximum acceptable material depends on its thickness, shape, strength and feeding position.

2. What is the difference between a box shear and a gantry shear?

A box shear compresses scrap inside an integrated feeding box before pushing it toward the blade. It is suitable for bulky, long and tangled scrap. A gantry shear generally uses a larger open loading chamber and is more suitable for high-volume, heavy-duty scrap processing.

3. What is the hourly processing capacity?

Capacity is not determined by cutting frequency alone. It depends on scrap density, loading efficiency, material thickness, cut length and operator experience. Representative material information is required for a reliable output estimate.

4. Can the machine be operated by remote control?

Yes. The Q43W-4000 can be supplied with PLC control and remote operation. This allows the operator to control major machine movements while maintaining a clear view of the loading and cutting area.

5. How often should the blades be replaced?

Blade life depends on the processed material, operating hours, blade clearance and the presence of hardened or contaminated scrap. The blades should be inspected regularly and can normally be turned, sharpened or replaced according to their condition.

6. What after-sales support is available?

WANSHIDA provides installation guidance, foundation drawings, operating manuals, electrical documentation, spare-parts support and remote technical assistance. On-site installation and commissioning can also be arranged. The standard warranty is 12 months, subject to the final contract.

For a suitable Q43W-4000 configuration, provide the scrap type, maximum material dimensions, required daily capacity, local voltage and preferred loading-box size.
