Heavy Duty Gas Springs: Solutions for Industrial Loads
Heavy Duty Gas Springs: Solutions for Industrial Loads
When you are dealing with a 500kg armored vehicle door or a massive industrial machine guard, a standard gas spring just won't cut it. You need a Heavy Duty Gas Spring.
Designed for the toughest environments and heaviest loads, these components are the muscle of the motion control.
What Defines "Heavy Duty"?
Standard gas springs typically top out at around 2,500N (approx. 250kg) of force. Heavy duty models push this boundary significantly:
- Force Range: 2,000N to 5,000N (500kg) or even higher on custom orders.
- Rod Diameter: Thicker rods (20mm, 25mm, or 30mm) to prevent buckling under load.
- Cylinder Diameter: 40mm to 70mm to contain the high-pressure nitrogen.
Key Features
- Robust Seals: Enhanced sealing systems to withstand extreme internal pressures (often exceeding 150 bar).
- End Fittings: Heavy-duty springs often feature stronger end fittings for maximum structural integrity.For example, with a 2,500N gas spring, the force can reach 3,000N when fully compressed. In such cases, we would recommend using an M16 end fitting to ensure an adequate safety factor. 
- Safety Features: Often equipped with mechanical locking tubes to physically prevent the lid from falling if seals fail.
Typical Applications
- Military Vehicles: Armored hatches, engine covers, and ramp doors.
- Construction Machinery: Excavator hoods, maintenance access panels.
- Manufacturing: Heavy stamping press guards, large conveyor belt tensioners.
- Roof Hatches: Large smoke vents or heavy glass skylights.
Selection Tips
When selecting a heavy-duty spring, safety is paramount:
- Safety Factor: Always calculate with a higher safety factor (e.g., 1.3x instead of 1.1x).
- Mounting: Ensure your mounting points (brackets/hinges) are strong enough. A 5,000N spring exerts half a ton of force—weak brackets will rip right off.
- Professional Calculation: Do not guess. Contact our engineering team for a full simulation.
