Explosion Proof Single Girder Overhead Crane – Key Advantages & Features

1. High Safety for Explosive Environments

• Certified Protection: Meets ATEX & GB standards (JB/T10219-2001) with ExdII BT4/CT4 protection grades.

• For Hazardous Areas: Works in Zone 1 & 2 (per GB 3836.1-2000), handling flammable gases (IIB/IIC) with ignition temps ≥ T4.

• No Sparks: Travel mechanism prevents ignition in high-risk areas (when rated ExdII CT4).

2. Reliable Components

• Explosion-Proof Parts: Hoist, motor, and controls use Exd-certified components.

• Top-Quality Brands: Optional motors/gearboxes from leading suppliers.

• Easy Control: Choose ground pendant or cabin operation.

3. Strong and Durable Design

• Smooth Operation: Handles ≤120 starts/hour (25% duty cycle).

• Heavy-Duty Build: Steel frame with anti-corrosion coating (custom options for outdoor use).

• Easy Maintenance: Modular design for quick repairs.

4. Safety Protections

• Overload Prevention: Stops motor burnout and damage.

• Emergency Features: Includes stop buttons, limit switches, and hook latches.

• Tested Quality: All parts checked before assembly.

5. Affordable and Efficient

• Low Cost: High safety without high prices.

• Fast Setup: Easy to install/dismantle.

• Wide Use: Works in -20°C to 40°C, ≤85% humidity, and elevations <1000m.

Ideal for:
✔ Petrochemical plants
✔ Pharmaceuticals & chemicals
✔ Mining/oil rigs
✔ Grain silos & fuel storage

Additional Details (Translated from Chinese Content):

• Design Basis: Improved from "LD-type" cranes per GB 3836.1/2-2000 standards, with stronger structure and explosion-proof features.

• Compatibility: Pairs with BCD/BMD/HB explosion-proof hoists (0.5t–32t capacity, 7.5–22.5m span).

• Operation Modes: Ground or cabin control (open/closed cabin, left/right entry options).

• Usage Limits: For factories/warehouses; not for flammable, explosive, or corrosive environments.

Pre-Operation Checks:

1. Inspect main beam connections.

2. Check wheels for cracks/wear (replace if damage >3mm deep).

3. Ensure electrical wires are secure.

4. Verify proper grounding.

Operation Steps:

1. Test-run the crane and position it above the load.

2. Secure the load and lift.

3. Move carefully under supervisor’s guidance.

4. After use, park the crane, turn off power, and clean the area.

Safety Rules:

• Operators must pass training and certification.

• Follow the "10 No-Lift" rules (e.g., no overload, unsafe binds, or unclear signals).

• Never lift over people; keep others away from loads.

• Maintain 3+ wire rope loops on the drum.

• Shut down and report faults immediately.

• If power fails, set controls to zero and mark hazard zones.

• Lower loads slowly—no free-falling.
