Key Facts About BZ5/5t-15/17m Explosion-Proof Pillar Jib Crane
The six most valuable FAQs for buyers — covering what this crane is, how to read its model number, its key lifting specifications, explosion-proof rating, power & control options, and why it is essential for hazardous area material handling.
1. What is this explosion-proof pillar jib crane and what is it designed for?
This is a BZ5/5t-15/17m Explosion-Proof Pillar Jib Crane with a dual 5-ton lifting capacity, designed for hazardous area material handling in chemical plants, oil refineries, and gas processing facilities. It is specifically configured with ExdIICT4 explosion-proof certification for safe operation in Zone 1 and Zone 2 explosive gas environments.
Ideal applications: chemical reactors, oil refinery maintenance, gas cylinder storage, pharmaceutical processing, paint spray booths, and offshore platforms.
Alternative names for this crane: flameproof jib crane, hazardous area pillar crane, ExdIICT4 crane, chemical plant jib crane, Zone 1 jib crane, dual hoist explosion-proof crane.
2. What does "BZ5/5t-15/17m" mean in the model number?
- BZ = BZ series jib crane (column-mounted slewing jib)
- 5/5t = Dual 5-ton lifting capacity (Primary + Secondary hoist)
- 15/17m = Primary valid radius 15.0m / Secondary reach 17.0m
- A3 = ISO A3 duty class
- ExdIICT4 = Explosion-proof rating (Gas Group IIC, Temperature Class T4)
The primary BCD electric hoist operates at 15.0m valid radius, while the secondary backup chain hoist extends to 17.0m reach on a 2m cantilever. This dual-hoist design ensures zero downtime during maintenance or power loss.
3. What are the key lifting specifications?
| Primary Capacity | 5.0 t |
| Secondary Capacity | 5.0 t |
| Lifting Height | 10.0 m |
| Primary Valid Radius | 15.0 m |
| Secondary Reach | 17.0 m |
| Hoisting Speed | 8.0 m/min |
| Rotation Angle | 360° |
| Rotation Speed | 0.2 r/min |
| Traveling Speed | 10 m/min |

Buyer Tip: If your lifting height exceeds 10m or you need a different working radius, Yuantai can customize the column height and beam length to suit your specific hazardous area layout.
4. What is the ExdIICT4 explosion-proof rating and what does it mean for my application?
The explosion-proof rating is ExdIICT4, which means:
- Ex = Explosion-proof equipment
- d = Flameproof enclosure (contains internal explosion without spreading)
- II = Equipment group II (surface industries, not mining)
- C = Gas group IIC (covers Hydrogen, Acetylene, and other most easily ignited gases)
- T4 = Temperature class T4 (maximum surface temperature ≤ 135°C)
What does this mean for you? This crane is suitable for Zone 1 and Zone 2 hazardous areas where explosive gas mixtures may be present. It is certified for the most demanding gas groups (IIC) including hydrogen and acetylene.
Explosion-proof rating comparison: ExdIIBT4 = covers common industrial gases (propane, ethylene), ExdIICT4 = covers hydrogen, acetylene, and all lower gas groups — the highest level of protection.
5. What power supply and control options does this crane require?
Power Supply:
- Crane: 380V / 50Hz / 3-Phase
- Lifting Motor (Primary): 7.5 kW (Flameproof Exd)
- Trolley Traveling Motor: 0.8 kW (Flameproof Exd)
- Control Voltage: 24V / 36V Low Safety Voltage
Control Modes:
- Explosion-proof pendant control — wired handheld controller with flameproof enclosure
- Explosion-proof wireless remote control — wireless operation for flexible positioning
Buyer Note: Pre-configured for 380V/50Hz 3-phase power. If your facility uses a different voltage (e.g., 220V, 415V, 440V, or 60Hz), please inform us during inquiry for customization to your local explosion-proof standards.
6. Why is this explosion-proof crane essential for hazardous area material handling?
- ExdIICT4 certification — safe operation in Zone 1 and Zone 2 explosive gas environments
- Dual 5t hoists — primary BCD electric hoist + secondary manual backup for zero downtime
- 15m/17m extended reach — covers large chemical reactors and storage tanks
- 360° rotation — complete circular coverage from a single column
- 10m lifting height — handles tall process equipment and vessels
- Flameproof motors and controls — all electrical components rated ExdIICT4
- Maintenance platform & ladder — safe access for inspection at height
- Non-sparking components — copper-coated hook and non-sparking trolley wheels
- Explosion-proof pendant + remote — operator can work from safe distance
- Heavy-duty construction — 22.3t structural weight for stability and durability
Why buyers choose this model: It provides the highest level of explosion protection (IIC, T4) combined with dual hoist redundancy and extended reach, making it essential for critical hazardous area operations where safety and uptime are paramount.
