Key Facts About BZ3t-3.5m Compact 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 light indoor material handling.
1. What is this crane and what is it designed for?
This is a BZ3t-3.5m Compact Pillar Jib Crane with a 3-ton lifting capacity, designed for indoor light material handling and workshop assembly. It is specifically configured for handling light engines, gearboxes, and general workshop components during maintenance and assembly operations.
Ideal applications: automotive engine assembly, small gearbox repair, light fabrication, and maintenance workshops with limited headroom.
2. What does "BZ3t-3.5m" mean in the model number?
- BZ = BZ series jib crane (column-mounted slewing jib)
- 3t = Maximum lifting capacity of 3.0 metric tons
- 3.5m = Total jib arm length of 3,500 mm (3.5 meters)
The valid working radius is 3.5 meters (3500 mm) from the pivot center to the hoist hook. This means the crane can lift 3 tons at a maximum distance of 3.5 meters from the column center.
3. What are the key lifting specifications?
| Lifting Capacity | 3.0 t |
| Lifting Height | 1.3 m |
| Valid Radius | 3.5 m |
| Hoisting Speed | 2.2 m/min (single speed) |
| Rotation Angle | 120° |
| Rotation Speed | 0.8 r/min |
| Traveling Speed | 11 m/min |
| Duty Class | A4 |
| Hoist Model | 3t Chain Hoist |
| Column Height | 2.8 m |
Buyer Tip: If your lifting height exceeds 1.3m 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 A4 and what does it mean for my application?
The duty class is A4 (FEM/ISO classification), which means:
- Medium duty cycle — suitable for regular intermittent use
- Rated for up to 1,000–2,000 hours of operation per year
- Ideal for workshops, assembly lines, and light maintenance facilities
- Perfectly matched to the regular but light nature of component assembly and handling work
What does this mean for you? If your workshop operates 1–2 shifts per day with moderate lifting frequency, A4 is the right duty class. For heavier, continuous operations, consider A5 or A6 duty cranes.
5. What power supply and control options does this crane require?
Power Supply:
- Hoist: 415V / 50Hz / 3-Phase
- Crane: 380V / 50Hz / 3-Phase
- Lifting Motor: 1.5 kW
- Traveling Motor: 0.75 kW
Control Modes:
- Pendant control — wired handheld controller with 24V/36V safety voltage
Buyer Note: Pre-configured for 415V/380V 50Hz 3-phase power. If your facility uses a different voltage (e.g., 220V, 440V, 480V, or 60Hz), please inform us during inquiry for customization.
6. Why is this crane suitable for light engine and component assembly?
- 3t capacity — handles light engines, gearboxes, and workshop components
- 120° rotation — positions loads over workbenches and assembly areas
- Motorized trolley travel — enables efficient movement along the jib arm
- 3.5m working radius — covers a practical work area from a single column
- A4 duty class — matches the regular but light nature of assembly work
- Indoor use — protected from harsh environments
- Pendant control — simple, reliable operation with good visibility
- Low headroom design — only 2.8m total height, ideal for workshops with low ceilings
- Compact footprint — minimal floor space required for the column base
Why buyers choose this model: It offers the perfect balance of lifting capacity, reach, and compact design for workshops where space and headroom are limited, but reliable 3-ton lifting is still required.
