PLC-Controlled 4000KN Scrap Metal Box Shear For Automated Scrap Yards With Advanced Technology

Product Overview

The Q43W-4000 box shear is a PLC-controlled hydraulic scrap cutting machine developed for recycling companies seeking to reduce manual handling and create a more organized production process.

Traditional scrap preparation often requires workers to reposition material repeatedly, operate separate compression equipment or use manual cutting methods. The Q43W-4000 combines loading, compression, hydraulic feeding and shearing in one coordinated system.

Its 4000 kN cutting force and 1400 mm blade allow the machine to process a wide range of mixed ferrous scrap. After material is loaded into the box, the hydraulic compression mechanism reduces its profile. The pusher then feeds the compressed scrap toward the blade according to the selected cutting length.

PLC control manages the working sequence, while optional remote operation allows the operator to control major movements from a suitable observation position. This combination makes the Q43W-4000 particularly suitable for modern scrap yards that require stable operation, fewer manual interventions and better coordination between loading and cutting.

Cause: Manual Scrap Preparation Creates Safety and Efficiency Risks

Bulky scrap is often unstable, sharp and difficult to position. When workers must repeatedly approach the loading or cutting area, production becomes slower and the potential for unsafe contact with moving material increases.

Common problems include:

• Frequent manual repositioning of irregular scrap
• Workers operating close to sharp or unstable material
• Inconsistent feeding length and cut dimensions
• Delays between loading, compression and cutting
• Excessive dependence on operator experience
• Poor coordination between excavator and machine operators
• Increased risk of incorrect operation
• Long preparation time before each cutting cycle

These problems become more serious when a recycling yard processes mixed materials throughout a full working shift.

Solution: Integrate Machine Movements Through PLC Control

The Q43W-4000 hydraulic box shear uses a programmed control system to coordinate compression, material feeding, blade movement and pressure release.

Instead of manually controlling every hydraulic movement, the operator can select the required operating mode and supervise the working sequence. Automatic operation helps maintain a consistent process, while manual mode remains available for adjustment, testing and maintenance.

Important operating advantages include:

• PLC-controlled compression and cutting sequence
• Remote control available for key machine movements
• Reduced manual contact with scrap material
• Consistent hydraulic feeding
• Adjustable cut length
• Automatic and manual operating modes
• Emergency-stop and safety-interlock configuration
• Centralized monitoring of machine status
• Easier coordination with excavator loading
• Reduced dependence on manual gas cutting

The electrical control system can be configured according to the customer’s local voltage, frequency, safety requirements and preferred electrical components.

Specifications

Technical specifications may be adjusted according to the loading-box dimensions, hydraulic components, electrical standard, operating climate and processed material.

Application

The Q43W-4000 automated scrap shear is suitable for facilities where continuous material flow, centralized operation and reduced manual cutting are important.

Modern Scrap Recycling Yards

The machine helps scrap yards establish a coordinated process between excavator loading, hydraulic compression, cutting and finished-material collection.

Steel Production Facilities

Steel mills can use the box shear to prepare mixed scrap to more consistent dimensions before furnace charging.

Industrial Dismantling Sites

Appropriately prepared machinery frames, pipes, profiles and structural components can be processed without extensive manual cutting.

Automotive Recycling Centers

Dismantled and drained automotive sheet metal can be compressed and cut into manageable sections for further recycling.

Metal Fabrication Plants

Steel frames, sheet offcuts, pipes and rejected products can be processed within the plant instead of being transported as bulky loose scrap.

High-Labor-Cost Markets

The integrated PLC control system is particularly useful in regions where reducing repetitive manual work and improving process consistency are major purchasing considerations.

How It Works

1. The operator inspects the working area and selects manual or automatic mode.
2. An excavator or hydraulic grab loads scrap into the feeding box.
3. The hydraulic compression mechanism presses the material into a controlled profile.
4. The PLC confirms that the compression movement has reached the required position.
5. The hydraulic pusher moves the compressed scrap toward the cutting head.
6. The main cylinder drives the 1400 mm blade through the material.
7. The blade returns automatically after the cutting stroke.
8. The pusher advances the remaining material according to the preset feeding length.
9. The compression and cutting cycle repeats until the loading box is empty.
10. Sensors and safety interlocks monitor the working sequence and help prevent conflicting hydraulic movements.

How To Choose

Determine the Required Automation Level

Choose PLC automatic operation when the machine will run continuously or when consistent feeding and cutting cycles are required. Manual mode is more suitable for testing, adjustment and maintenance.

Confirm the Remote-Control Functions

Remote controls can be configured for loading-box movement, compression, feeding, blade operation and emergency stop. The required functions should be confirmed before the electrical system is finalized.

Review the Scrap Characteristics

Provide the maximum material dimensions, thickness, shape and steel grade. Very thick solid bars or hardened steel may require a material test or a larger shearing model.

Consider the Operating Climate

High ambient temperatures or continuous multi-shift operation may require a larger oil tank, air cooler or water-cooling system to control hydraulic-oil temperature.

Plan the Operator’s Position

The operator should have a clear view of the loading box, shearing head and discharge area. Control-panel and remote-control positions should be considered during site-layout planning.

Confirm Local Safety Requirements

Emergency stops, protective covers, warning lights, access controls and electrical components can be configured according to the customer’s local regulations and internal safety standards.

FAQ

1. Can one operator control both loading and cutting?

Remote operation may allow the excavator operator to control selected machine functions. However, the final operating arrangement depends on the customer’s site layout, local safety requirements and internal working procedures.

2. Does the machine have a manual operating mode?

Yes. The Q43W-4000 can operate in both automatic and manual modes. Manual mode is used for commissioning, adjustment, maintenance and clearing material when necessary.

3. What happens if scrap becomes stuck during feeding?

The operator can stop the automatic cycle and use manual control to reverse or reposition the hydraulic pusher. The machine should be fully stopped and isolated before anyone enters a restricted area.

4. Is an oil cooler necessary?

An air cooler is recommended for continuous operation or warm climates. A larger or customized cooling system may be required when the machine operates for long shifts in high ambient temperatures.

5. Can the PLC and electrical components be customized?

Yes. PLC brand, electrical components, voltage, frequency, control language and remote-control functions can be selected according to project requirements and component availability.

6. What technical documents are supplied?

Available documents include foundation drawings, electrical diagrams, hydraulic diagrams, operating instructions, maintenance guidance and spare-parts information. The final document package depends on the confirmed contract.

To configure the control and safety system correctly, provide the scrap details, daily working hours, local power supply, preferred operating mode and required remote-control functions.
