Explosion proof manual carts are irreplaceable in specific high-risk environments, and their design, certification, and application must strictly comply with safety regulations. The following analyzes its core value from three aspects: technical characteristics, application scenarios, and compliance:

1、 Design Principles and Explosion proof Core

Material selection

Using copper alloy, stainless steel or anti-static plastic to avoid sparks caused by friction.

Use conductive rubber or metal wheels for tires to ensure that static electricity is promptly dissipated.

structural safety

Spark free braking system (such as copper brake pads).

Closed bearing design to prevent sparks from splashing.

Grounding chain/grounding wire configuration, in compliance with ATEX or NFPA explosion-proof standards.

Flexibility and adaptability

Modular shelf design, suitable for special goods such as gas cylinders and chemical drums.

The combination of low center of gravity and universal wheels enhances maneuverability in narrow spaces.

2、 Typical application scenarios

petrochemical industry

Transport lubricating grease or small equipment in refineries and oil storage facilities to avoid sparks caused by tool collisions.

Pharmaceutical and Laboratory

Transport solvents or volatile reagents in accordance with the fire prevention requirements of clean rooms.

Military and hazardous chemical storage

Transporting ammunition boxes or explosive precursors requires UN/DOT transport certification.

Underground mine

Transportation equipment accessories in coal/metal mines must be explosion-proof and waterproof (IP65 rating).

3、 Compliance and Market Status

Certification standards

ATEX (EU): Suitable for gas/dust explosion environments.

IECEx (International Electrotechnical Commission): globally recognized certification.

UL/FM (North America): focuses on structural and material testing.

Procurement precautions

Verify third-party testing reports (such as T Ü V or CSA certification).

Confirm the explosion-proof level (such as IIA/IIB/IIC corresponding to different explosive gases).

Choose manufacturers with ATEX QAN certification to ensure full chain compliance.

4、 Future Trends

Intelligent upgrade: Integrate IoT sensors to monitor temperature/pressure and alert potential risks.

Lightweight design: using carbon fiber composite materials to reduce the burden on operators.

Multi scenario adaptation: Develop special models suitable for low temperature (-40 ℃) or high temperature (200 ℃) environments.
