Product Features
Professional Torque Parameter System: The BZ Type offers a maximum restoring torque M (t·m) parameter rarely seen in the industry. Models BZ0.5 to BZ5 cover a range of 3 to 18.8 t·m, allowing engineers to verify actual load capacity based on radius and avoid overload risks.
Extensive Horizontal Travel Coverage: Maximum horizontal travel L₂ covers 2.3 to 4 m, with slewing radius R₂ of 3 to 5 m and 360° full rotation, adapting to various workstation layouts.
Flexible Two-Speed Hoisting: Normal speed of 8 m/min (4 m/min optional) for efficient daytime lifting, and slow speed of 0.8 m/min (0.4 m/min optional) for precision assembly.
High Load-to-Dead Weight Ratio: The BZ series features optimized section design. The BZ5 has a dead weight of only 4300 kg while handling 5 tons, requiring no reinforced foundation for installation.
Multiple Power Options: Choose from manual, semi-electric, or fully electric operation to match budget and efficiency requirements.
Non-Standard Customization: Lifting capacity, slewing radius, travel, and other parameters can all be customized to the specific workstation.
Working Principle
The working principle of the BZ Type Pillar Jib Crane: The column is fixed to a concrete foundation with anchor bolts, and the cantilever is connected to the column via the slewing mechanism. An electric slewing drive or manual drive rotates the cantilever 360° around the column. The electric hoist (wire rope hoist or chain hoist) is mounted on the cantilever rail and travels horizontally along the cantilever. During lifting, the electric hoist raises the load vertically, and the cantilever slews to transport the load horizontally to the target position, achieving full-coverage lifting within the workstation.
Product Structure
The BZ Type Pillar Jib Crane consists of the following core components:
Column: Fixed to the concrete foundation, serving as the main load-bearing structure of the entire unit.
Cantilever: Connected to the column via the slewing bearing, enabling 360° flexible rotation.
Slewing Mechanism: Manual, semi-electric, or electric slewing drive for smooth rotation of the cantilever.
Hoisting Mechanism: Wire rope single/two-speed electric hoist or chain electric hoist, mounted on the cantilever rail.
Electrical Control System: Pendant push-button control or wireless remote control, including hoisting limit control.
Safety Devices: Hoisting limit switch, emergency stop button, etc.

Operating Instructions
Pre-Operation Checks: Inspect the electric hoist wire rope/chain for damage, verify the limit switches are functioning, listen for abnormal noise from the slewing mechanism, and confirm the anchor bolts are properly tightened.
Start-Up: Connect the power supply and use the pendant control or wireless remote control to operate hoisting, trolley travel, and jib slewing.
Lifting Operations: Keep the load stable during lifting. Watch for nearby personnel and obstacles when slewing the jib. Never exceed the rated lifting capacity.
Shutdown & Maintenance: After operations, park the hoist in the designated position and switch off the power. Periodically check slewing bearing lubrication, bolt tightness, and electrical insulation.

FAQ
Q: How is the "maximum overturning moment M" in the BZ Type parameter table used in crane selection?
A: The maximum overturning moment M (t·m) = rated lifting capacity × maximum working radius. It determines the heaviest load that can be safely lifted at a given radius. For example, the BZ5 has M = 18.8 t·m; at a working radius of 5 m, the maximum lifting capacity = 18.8 ÷ 5 ≈ 3.76 t (below the rated 5 t; always refer to the nameplate for actual values). When selecting a crane, verify that the moment requirement is met based on your specific working radius.
Q: What is the difference between the BZ Type and BZD Type column cantilever cranes?
A: Both the BZ and BZD types are pillar jib cranes, but they differ in model coding and dimensional parameters. The BZ Type provides more detailed overall dimension configurations (L/L₁/R₂/R₁/H/h) and moment parameters, making it adaptable to a wider range of workspace layout requirements.
Q: Which design standards apply to the BZ Type pillar jib crane, and how is the moment parameter verified?
A: Design & manufacturing comply with GB/T 3811 Crane Design Standard and JB/T 8906 (Jib Crane standard). The maximum overturning moment M listed in the parameter table is verified in accordance with the load combination calculation method in Section 5.3 of GB/T 3811. The slewing mechanism undergoes durability validation per Appendix A of JB/T 8906, and the safety devices meet the requirements of TSG Q7014.
Q: How much does a BZ Type column cantilever crane cost?
A: Pricing varies by lifting capacity and slewing radius: small units (0.25–0.5 t) range from ¥8,000–18,000; medium units (1–2 t) from ¥20,000–45,000; and large units (3–5 t) from ¥40,000–80,000. Final pricing depends on non-standard requirements such as working radius, lifting height, and special features.
