Details
1. Introduction
The Hydraulic Spreader Machine is a specialized high-force tool designed for critical operations where rapid and controlled spreading, pulling, or lifting is essential. Originally developed for emergency rescue operations such as vehicle extrication, the hydraulic spreader has evolved into a multifunctional solution across multiple sectors including fire and rescue, civil defense, industrial maintenance, and heavy engineering.
The SHS-600 model, manufactured by Neometrix Defence Limited, embodies the cutting-edge of hydraulic tool technology. It combines robust engineering, ergonomic control, and modular adaptability to perform effectively in some of the harshest and most unpredictable environments. The machine is driven by high-pressure hydraulics and features arms that can exert up to 840 kN of force, making it capable of separating thick steel components, prying open structural enclosures, or pulling apart jammed mechanical assemblies with minimal user effort.
2. Applications
The SHS-600 hydraulic spreader is built to serve diverse applications across several sectors. It is not limited to one industry but rather spans both emergency response and heavy-duty industrial environments.
Emergency and Rescue Operations:
▹ Vehicle Extrication: Used by fire departments and emergency responders to remove doors, roofs, and other components of crashed vehicles without causing further harm to passengers.
▹ Building Collapse & Disaster Relief: Shifts debris, pries open metal frames, and lifts panels that may be trapping survivors beneath in earthquake or explosion zones.
Industrial Use Cases:
▹ Heavy Machinery Maintenance: Facilitates the disassembly of tightly-fitted or seized machine parts, opening stuck hatches or pushing apart steel housings.
▹ Shipyards and Aerospace Manufacturing: Assists in aligning or adjusting large fabricated metal panels and frames, and dismantling obsolete structures.
Specialized Military and Defense Use:
▹ Combat Engineering & Armory Access: Provides rapid access in armored vehicles or bunkers in tactical situations requiring breach or rescue.
▹ Ordnance Disposal: Adapted for controlled separation of explosive containers or to create safe access for robotic intervention tools.
3. Key Features
▹ High Spreading Force: The spreader arms can deliver up to 840 kN (≈84 tonnes) of force, making it capable of moving extremely heavy materials with ease.
▹ Wide Operational Range: A spread distance of 740 mm allows insertion into tight gaps and then expansion with tremendous force, suitable for both confined and open spaces.
▹ Dual Functionality: Can be reconfigured for pulling operations using specialized attachments, delivering a pulling force of 71 kN over a 600 mm stroke.
▹ 360° Control Handle: The handle rotates completely around the central axis, offering user-friendly access in awkward positions and an integrated automatic return mechanism
▹ Advanced Coupling System: Equipped with both mono-coupler and twin-line male/female hydraulic connectors for compatibility with various power packs.
▹ Safety & Durability: Constructed with aircraft-grade aluminum alloy and hardened steel tips, featuring pressure relief valves, protective dust caps, and a high-strength locking central bolt.

5. Operation
Setup:
▹ Attach hydraulic hoses from a compatible pump system (output ≥ 720 bar).
▹ Ensure couplings are locked and dust caps removed before connecting.
Spreading Action:
▹ Rotate the 360° handle to the forward position; arms open with hydraulic pressure.
▹ Guide the arms into the required position while monitoring spread.
Pulling Action:
▹ Install the optional pulling attachment or chain.
▹ Activate hydraulic tensioning through the control handle for separation.
Shutdown:
▹ Return control valve to neutral to halt movement.
▹ Disconnect power source and cover couplings with dust caps.
Storage:
▹ Retract arms to a neutral position.
▹ Store in a clean, dry case or compartment.
6. Maintenance and Inspection
Every Use:
▹ Clean couplers, inspect for damage, and test operation.
20 Hours / Monthly:
▹ Inspect hand-valve operation and hose connections.
50 Hours / Quarterly:
▹ Test pressure relief valve and return mechanism.
100 Hours / Semi-Annually:
▹ Check central bolt tightness and piston rod movement.
200 Hours / Yearly:
▹ Comprehensive inspection by certified technician.
▹ Replace hoses if necessary.
7. Troubleshooting
Slow Blade Opening:
▹ Cause: Air trapped in hydraulic circuit.
▹ Remedy: Cycle the spreader to purge air.
Stuck Control Handle:
▹ Cause: Damaged return spring.
▹ Remedy: Replace spring with OEM part.
Hydraulic Leakage at Rod:
▹ Cause: Worn piston seal.
▹ Remedy: Service by qualified technician.
Arms Do Not Retract Fully:
▹ Cause: Dirt in cylinder or spring wear.
▹ Remedy: Clean tool or replace spring assembly.
8. Conclusion
The SHS-600 hydraulic spreader is a critical tool for emergency services and industries requiring quick, controlled high mechanical force. Its durability, versatility, and safety features make it an optimal choice for life-saving and industrial interventions. Neometrix Defence Limited ensures each SHS-600 meets rigorous quality standards and is backed by technical documentation, after-sales service, and operational training, making it the preferred tool for professional responders and field engineers globally.
