What is an Explosion-proof transfer cart?
Explosion-proof transfer cart, also called ATEX/IECEx Certified Transfer Cart, is an industrial handling equipment specifically designed for flammable and explosive environments. It is used in places with explosive gases or dust, such as chemical plants, petrochemical plants, coal mines, military enterprises, and spraying workshops. The equipment must comply with explosion-proof standard structural designs, special explosion-proof materials, and electrical systems to prevent sparks or high temperatures from causing danger. Usually running along fixed tracks and supporting remote or wire control operations, it has a load capacity of 1–300 tons. Some models also integrate customized functions such as automatic dumping and high-temperature resistance, achieving safe and stable material transportation in hazardous environments.

| Static Protection | Tires and the vehicle body must be conductive with a grounding resistance of < 100Ω to ensure real-time discharge. |
| Temperature Control | Maximum surface temperature must be strictly graded based on environmental substances (e.g., T4 level ≤ 135°C). |
| Certification & Marking | Must be certified by agencies like NEPSI; nameplates must clearly state explosion-proof marks and applicable hazardous zones. |
| Operation & Training | Operators must be certified; installing non-explosion-proof accessories is prohibited, and charging must occur in safe areas. |
| Regular Inspection | Professional organizations must perform annual inspections of flameproof surface integrity and grounding continuity. |
The safety standards for Explosion-proof transfer cart center on the GB/T 19854-2018 and GB/T 26950 series. From design and manufacturing to use and maintenance, they ensure the elimination of ignition source risks in explosive environments. Enterprises must choose products that have passed authoritative certification and strictly implement regular inspections and personnel training to meet compliance requirements and ensure operational safety.

ВОПРОСЫ И ОТВЕТЫ
Q1: What is an explosion-proof rating ?
A: This is a safety certification label: Ex refers to explosion-proof; d is flameproof; IIB is adapted to gas groups like ethylene; T4 limits the equipment surface temperature to not exceed 135°C. It must be matched according to the on-site medium.
Q2: How to prevent sparks from mechanical collisions?
A: Use “soft treatment”: The cargo platform is laid with explosion-proof copper plates or stainless steel, and rotating parts use non-sparking bearings and seals to eliminate collision and friction sparks at the physical level.
Q3: Are there special requirements for the wheels of explosion-proof cars?
A: They must be anti-static. Anti-static polyurethane wheels are used in conjunction with a grounding conductive chain to ensure that static electricity generated during operation can be exported to the ground in real-time, preventing electrostatic discharge (ESD) from causing an explosion.
Q4: Can it be used outdoors or in humid environments?
A: Yes. The equipment has a high protection rating of IP65/IP66. In addition to being explosion-proof, it also has waterproof, dustproof, and anti-corrosion properties, suitable for chemical plants and outdoor loading stations.
Q5: Is the power source of the explosion-proof transfer car safe?
A: Yes. It uses a flameproof sealed battery box (storage battery or lithium battery) with built-in hydrogen leakage monitoring and overheating protection systems to ensure the power system does not become an ignition source in hazardous areas.
Q6: What is different about the navigation system of an explosion-proof AGV?
A: The hardware must have certification. All LiDAR, cameras, and sensors must be installed in explosion-proof enclosures or select special sensors that have passed intrinsic safety certification.
Q7: How to ensure an instantaneous stop in an emergency?
A: Adopt multi-redundancy braking (electromagnetic + mechanical braking). Combined with explosion-proof grade laser obstacle avoiders, the system response time is as low as 0.3 seconds, ensuring immediate braking even under full load.
Q8: How long does it take to customize an explosion-proof car?
A: Due to special selection and strict explosion-proof testing, the cycle is usually 8–12 weeks. Every piece of equipment must undergo rigorous safety certification before leaving the factory.
