Key Facts About BZ3t-8m Freestanding Pillar Jib Crane
The six most valuable FAQs for buyers — covering what this freestanding crane is, how to read its model number, its key lifting specifications, duty class, power & control options, and why it is ideal for heavy-duty freestanding indoor material handling.
1. What is this freestanding pillar jib crane and what is it designed for?
This is a BZ3t-8m Freestanding Pillar Jib Crane with a 3-ton lifting capacity, designed for heavy-duty indoor material handling in large workshops. It is specifically configured for lifting heavy machinery components, servicing large equipment, and handling loads with extended reach and 360° coverage. Unlike building-mounted jib cranes, this freestanding model requires no structural support from your building.
Ideal applications: heavy machinery workshops, large equipment maintenance bays, mining equipment repair shops, steel fabrication plants, facilities needing 360° rotation, and high-duty cycle operations requiring A5 rated equipment.
Alternative names for this crane: standalone jib crane, self-supporting pillar crane, free-standing pillar jib crane, independent jib crane, floor-mounted jib crane.
2. What does "BZ3t-8m" mean in the model number?
- BZ = BZ series jib crane (freestanding pillar-mounted slewing jib)
- 3t = Maximum lifting capacity of 3.0 metric tons
- 8m = Valid working radius of 8,000 mm (8 meters)
The total beam length is 8.9 meters (8900 mm), with a valid working radius of 8.0 meters (8000 mm) from the pivot center to the hoist hook. This means the crane can lift 3 tons at a maximum distance of 8.0 meters from the column center.
Column height: 5.5 meters. Total crane height: 6.5 meters. Lifting height: 5.0m main plus 30.0m auxiliary.
3. What are the key lifting specifications?
| Lifting Capacity | 3.0 t |
| Lifting Height | 5.0 m + 30.0 m (Main + Auxiliary) |
| Valid Radius | 8.0 m |
| Total Beam Length | 8.9 m |
| Hoisting Speed | Dual Speed (0.45/3.2 kW) |
| Rotation Angle | 360° |
| Duty Class | A5 |
| Hoist Model | NR3t European Wire Rope Hoist |
| Total Height | 6.5 m |
| Column Height | 5.5 m |
| Hoist Headroom | 650 mm |
| Foundation Type | Freestanding (independent concrete) |
Buyer Tip: If your lifting height exceeds 5m or you need a larger working radius, Yuantai can customize the column height and beam length to suit your specific workshop layout. For taller lifting requirements, consider our tall pillar jib crane models.
4. What is the duty class A5 and what does it mean for my application?
The duty class is A5 (FEM/ISO classification), which means:
- Heavy duty cycle — suitable for regular daily use
- Rated for up to 2,000–4,000 hours of operation per year
- Ideal for heavy machinery workshops, large equipment maintenance, and high-frequency lifting
- Perfectly matched to the demanding nature of heavy-duty material handling
What does this mean for you? If your workshop operates multiple shifts per day with regular lifting, A5 is the right duty class. For occasional use, consider A3 or A4 duty cranes.
Duty class comparison: A3 = light duty (occasional use), A4 = medium duty (regular intermittent), A5 = heavy duty (regular daily), A6 = extra heavy duty (continuous).
5. What power supply and control options does this crane require?
Power Supply:
- Crane: 440V / 60Hz / 3-Phase
- Lifting Motor: 0.45 / 3.2 kW (Dual Speed)
- Traveling Motor: 0.44 kW
Control Modes:
- Pendant control — wired handheld controller with 24V/36V safety voltage
- Remote control — wireless operation for flexible positioning
Buyer Note: Pre-configured for 440V/60Hz 3-phase power. If your facility uses a different voltage (e.g., 220V, 380V, 415V, or 50Hz), please inform us during inquiry for customization.
Control options available: Pendant control, radio remote control, dual control (pendant + remote), and customized control panels for specific operational requirements.
6. Why is this crane suitable for heavy-duty freestanding indoor material handling?
- 3t capacity — handles heavy machinery components
- 8.0m working radius — exceptional horizontal reach for large workshops
- 360° rotation — complete circular coverage from a single column
- Dual lifting heights — 5m main plus 30m auxiliary for specialized applications

- A5 duty class — matches the demanding nature of heavy-duty work
- Pendant + remote control — operator can work from safe distance with good visibility
- Freestanding design — no building structure support required
- Indoor use — protected from harsh environments
- Independent foundation — can be installed in rental facilities or buildings not designed for crane loads
- Low headroom hoist — 650mm compact design maximizes available lifting height
Why buyers choose this freestanding model: It offers the perfect balance of lifting capacity, extended reach, comprehensive rotation, and heavy-duty rating for large workshops where reliable 3-ton lifting with 360° coverage is required. The freestanding design eliminates the need for building modifications, making it ideal for rental facilities and temporary installations.
