Key Facts About BZ3t-7m Heavy-Duty 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, duty class, power & control options, and why it is ideal for wide-reach indoor material handling.
1. What is this crane and what is it designed for?
This is a BZ3t-7m Heavy-Duty Pillar Jib Crane with a 3-ton lifting capacity, designed for indoor wide-reach material handling in large workshops. It is specifically configured for covering multiple workstations, loading and unloading across large work areas, and handling components with extended horizontal reach.
Ideal applications: wide workshops, multiple service positions, large work area coverage, and facilities needing 3t capacity with extended reach.
2. What does "BZ3t-7m" mean in the model number?
- BZ = BZ series jib crane (column-mounted slewing jib)
- 3t = Maximum lifting capacity of 3.0 metric tons
- 7m = Valid working radius of 7,000 mm (7 meters)
The total beam length is 7.8 meters (7800 mm), with a valid working radius of 7.0 meters (7000 mm) from the pivot center to the hoist hook. This means the crane can lift 3 tons at a maximum distance of 7.0 meters from the column center.
3. What are the key lifting specifications?
| Lifting Capacity | 3.0 t |
| Lifting Height | 3.65 m |
| Valid Radius | 7.0 m |
| Total Beam Length | 7.8 m |
| Hoisting Speed | 2.2 m/min |
| Rotation Angle | 270° |
| Rotation Speed | 0.4 r/min |
| Traveling Speed | 11 m/min |
| Duty Class | A3 |
| Hoist Model | 3t Chain Hoist (Ø7.1mm chain) |
| Total Height | 5.45 m |
| Hoist Headroom | 940 mm |
Buyer Tip: If your lifting height exceeds 3.65m or you need a larger working radius, Yuantai can customize the column height and beam length to suit your specific workshop layout.
4. What is the duty class A3 and what does it mean for my application?
The duty class is A3 (FEM/ISO classification), which means:
- Light duty cycle — suitable for occasional use
- Rated for up to 500–1,000 hours of operation per year
- Ideal for workshops, wide-bay facilities, and occasional lifting applications
- Perfectly matched to the occasional nature of wide-reach material handling
What does this mean for you? If your workshop requires occasional lifting with low frequency, A3 is the right duty class. For regular daily operations, consider A4 or A5 duty cranes.
5. What power supply and control options does this crane require?
Power Supply:
- Crane: 415V / 50Hz / 3-Phase
- Lifting Motor: As per configuration
- Traveling Motor: As per configuration
Control Modes:
- Pendant control — wired handheld controller with 24V/36V safety voltage
Buyer Note: Pre-configured for 415V/50Hz 3-phase power. If your facility uses a different voltage (e.g., 220V, 380V, 440V, 480V, or 60Hz), please inform us during inquiry for customization.
6. Why is this crane suitable for wide-reach indoor material handling?
- 3t capacity — handles heavy workshop components
- 7.0m working radius — exceptional horizontal reach for wide workshops
- 270° rotation — comprehensive coverage of work area
- Motorized trolley travel — enables efficient movement along the jib arm
- A3 duty class — matches the occasional nature of wide-reach work
- Pendant control — simple, reliable operation with good visibility
- Single chain hoist — reliable and easy to maintain
- Compact height design — only 5.45m total height, ideal for standard workshops
- Indoor use — protected from harsh environments
Why buyers choose this model: It offers the perfect balance of lifting capacity, extended horizontal reach, and comprehensive rotation for wide workshops where multiple workstations need to be covered from a single column.
