Explosion Proof Single Girder Overhead Crane

PRODUCT OVERVIEW

Explosion Proof Single Girder Overhead Crane – Key Advantages & Outstanding Features

1. Superior Explosion-Proof Safety Compliance

ATEX & GB Standards Certified: Meets JB/T10219-2001 (Explosion-Proof Crane Standard) with ExdII BT4 & ExdII CT4 protection grades.
Hazardous Zone Ready: Designed for Zone 1 & Zone 2 explosive environments (per GB 3836.1-2000), handling flammable gases (IIB/IIC) with ignition temps ≥ T4.
Spark-Proof Travel Mechanism: Ensures safe operation in high-risk areas (when rated ExdII CT4).

2. High-Performance Components

Explosion-Proof Motor & Electricals: Critical parts (hoist, decelerator, controls) use Exd-certified components.
Premium Brand Options: Motors and gearboxes from top-tier suppliers (customizable per client needs).
Flexible Control: Operated via ground pendant or cabin control for adaptability.

APPLICATION SCENARIO

Application Scenarios for Explosion Proof Single Girder Overhead Crane

This ATEX-certified overhead crane is specifically designed for hazardous environments where explosive gases, vapors, or dust-air mixtures are present. It is ideal for industries requiring strict explosion-proof compliance and safe material handling in high-risk zones.

Key Industrial Applications:

Oil & Gas Refineries

Safe lifting in fuel storage areas, petrochemical processing, and LNG plants where flammable gases (IIB/IIC) may be present.

Chemical & Pharmaceutical Manufacturing

Handling volatile solvents, combustible vapors, and explosive chemical mixtures in production/storage zones.

Paint & Coating Facilities

Spark-proof operation in environments with flammable solvents (e.g., ethanol, acetone) and aerosolized particles.

Mining & Coal Processing

Reliable material transport in methane-rich (Group I) or dust-explosive underground/processing areas.

Grain Silos & Food Processing

Explosion-proof lifting in flour, sugar, or starch facilities where combustible dust clouds may form.

Aerospace & Defense

Safe handling of fuel tanks, propellants, and volatile materials in assembly/storage zones.

Waste Treatment & Biofuel Plants

Corrosion-resistant operation in biogas or landfill gas (methane-rich) environments.

Compatible Hazardous Zones:

✔ Zone 1 & Zone 2 (GB 3836.1-2000) – Where explosive atmospheres occur occasionally or under abnormal conditions.
❌ Not for Zone 0 (continuous explosive atmosphere).

Environmental Adaptability:

Gas Groups: IIB (e.g., propane, ethylene) & IIC (e.g., hydrogen, acetylene).
Ignition Temp. ≥ T4 (≥135°C) – Safe for gases like ammonia, methanol, and diesel vapors.
Humidity & Altitude: ≤85% RH at 25°C, elevations <1000m.
