BZD Column Cantilever Crane for Precise Material Handling
Product Introduction
The Fixed Column Jib Crane (BZD series column cantilever crane) offers a rated lifting capacity of 250kg to 5000kg (0.25–5 tons), with a jib length of 2–20m and a maximum lifting height of 12m. It is ideal for light hoisting and handling operations on production lines, assembly lines, in warehouses, and at docks. The BZD fixed column jib crane features a column anchored to the concrete foundation, a jib that slews 360° electrically, and an electric hoist that travels along the jib for full-coverage lifting within the workstation.

Working Principle
The working principle of the BZD fixed column jib crane: The fixed column is anchored to the concrete foundation via anchor bolts. The jib is connected to the column through a slewing bearing, and an electric slewing mechanism drives the jib to rotate around the column. The matching electric hoist (or electric chain hoist) is mounted on the trolley rail on the lower flange of the jib and can move horizontally along the jib length. During lifting, the electric hoist raises the load vertically, and the slewing of the jib transports the load horizontally to the target position, achieving full-coverage handling within the designated workstation.
Product Structure
The BZD fixed column jib crane consists of the following core components:
Fixed Column: Fabricated from high-quality structural steel (welded or steel pipe), anchored to the concrete foundation via anchor bolts. It serves as the primary load-bearing structure of the entire crane.
Jib: I-beam or box girder construction, connected to the column via a slewing bearing, capable of 360° electric rotation.
Slewing Mechanism: Electric slewing drive unit that ensures smooth rotation of the jib.
Electric Hoist: Wire rope hoist or chain hoist, mounted on the trolley rail of the jib, moving horizontally along the jib.
Electrical Control System: Dual control with wired pendant and wireless remote, including hoisting, travel, and slewing controls.
Safety Devices: Hoisting limit switch, travel limit switch, Emergency Stop Button, etc.

Applications
The BZD pillar jib crane is widely used in the following scenarios:
Factory Workshops: Material handling and process transfer along production lines.
Assembly Lines: Hoisting and positioning of components during mechanical assembly.
Machine Tool Loading/Unloading: Handling heavy workpieces at machining centers, lathes, milling machines, and similar equipment.
Warehouses & Docks: Lifting and loading/unloading heavy loads in storage areas.
Die & Mold Maintenance: Hoisting and replacement of molds in tool rooms.
Maintenance Stations: Lifting operations during equipment repair and servicing.
Selection Guide

Operating Instructions
Pre-Operation Checks: Inspect the electric hoist wire rope/chain for damage, verify the limit switches are functioning properly, and listen for any abnormal noise from the slewing mechanism.
Start-Up: Connect the power supply and control hoisting, trolley travel, and jib slewing via the pendant or wireless remote control.
Lifting Operations: Keep the load stable during lifting, watch for personnel and obstacles when slewing the jib, and never exceed the rated capacity.
Shutdown & Maintenance: Park the hoist in the designated position and disconnect the power after operations. Periodically check slewing bearing lubrication, bolt tightness, and electrical insulation.

FAQ
Q: Why is the BZD jib crane the most common choice for workshop workstations?
A: The BZD series covers six capacity ratings from 0.25 to 5 tons with jib radii from 2 to 20 m, making it the most widely installed standard series in the jib crane segment. Compared to KBK systems (≤500 kg), it offers higher capacity; compared to the BZZ heavy-duty series (1–10 tons), it delivers better cost-effectiveness. It is the value choice for light-to-medium duty workstation lifting. Standard CD1/MD1 hoist components are readily available, keeping long-term maintenance costs low.
Q: What is the difference between a column cantilever crane and a mobile jib crane?
A: A column cantilever crane has its column fixed to a foundation, with the jib slewing to cover a fixed workstation — ideal for stationary workstations. A mobile jib crane (e.g., wall-traveling or KBK rail-mounted types) moves along rails, covering multiple stations over longer distances. The two have different structures and application scenarios; the choice depends on your workstation layout.
Q: Which design and manufacturing standards apply to BZD column cantilever cranes?
A: Design & manufacturing comply with GB/T 3811 Crane Design Standard and JB/T 8906 (Jib Crane Standard). The hoisting mechanism (CD1/MD1 electric hoist) complies with JB/T 9008 (Wire Rope Hoist Standard), and safety devices meet TSG Q7014 requirements.
Q: How much does a BZD column cantilever crane cost?
A: Pricing varies by lifting capacity and jib length. Small units (0.25–1 t) range from RMB 8,000–20,000; medium units (2–3 t) from RMB 20,000–40,000; and large units (5 t) from RMB 40,000–80,000. Final pricing depends on jib length, lifting height, and any non-standard customizations required.
