BZD Column Cantilever Crane for Material Handling
Product Introduction
The Column Cantilever Crane (BZD Column Cantilever Crane / BZ Series Column Cantilever Crane) offers a rated lifting capacity of 0.25 to 10 tons, with a jib length of 2 to 20 m and a maximum lifting height of 18 m. It is a lightweight material handling solution designed to work with chain electric hoists and wire rope hoists. The BZD column cantilever crane features a column anchored to a concrete foundation, with a jib that rotates 360° electrically or manually. The matching electric hoist travels along the jib to provide full-coverage lifting within the workstation.

Product Features
Dual Chain + Wire Rope System: The BZD/BZ series uniquely supports both chain hoists (quick installation, ideal for light-load high-frequency duty) and wire rope hoists (durable, suited for medium-load continuous operation), allowing one model to cover multiple working conditions.
Wide Capacity Range of 0.25–10 Tons: Eight capacity ratings make this the broadest-spanning model in the jib crane series. From miniature parts to heavy equipment, a single unit covers the full range of production line needs.
Multiple Beam Options: Compatible with I-beam, box girder (for heavy loads), and KBK track (for light loads) jib configurations, optimized by capacity and duty cycle.
Compact Footprint: The column-plus-jib design minimizes floor space, maximizing workshop utilization.
Flexible Manual/Electric Switching: Manual rotation is recommended for units up to 500kg to save cost; 1t and above come with electric slewing and electric trolley for enhanced efficiency.
Comprehensive Safety: Lifting limit switch, emergency stop, overload protection, and a full suite of safety devices come standard on all models.
Working Principle
The working principle of the BZD column cantilever crane is as follows: the column is secured to a concrete foundation via anchor bolts, and the jib connects to the column through a slewing bearing. The slewing mechanism (manual or electric) drives the jib to rotate around the column. The matching electric hoist (chain electric hoist or wire rope hoist) is mounted on the jib track and can move horizontally along the jib length. During lifting, the electric hoist raises the load vertically, and the slewing jib transports it horizontally to the target position, providing full-coverage lifting within a designated workstation.
Product Structure
The column cantilever crane consists of the following core components:
Column Assembly: Comprising upper and lower column sections, fabricated from high-quality structural steel or steel pipe via welding, secured to the concrete foundation with anchor bolts. This is the primary load-bearing structure of the entire unit.
Jib (Main Girder): I-beam, KBK track, or box girder construction (for heavy loads), connected to the column via a slewing bearing. Beam type is selected based on capacity.
Slewing Device: Manual slewing mechanism or electric slewing drive unit for smooth jib rotation.
Hoisting Mechanism: Chain electric hoist or wire rope hoist, mounted on the jib track, traveling horizontally along the jib.
Electrical Control System: Includes hoisting, travel, and slewing controls, with wireless remote control plus wired pendant as standard dual control.
Safety Devices: Lifting limit switch, travel limit, emergency stop button, overload protection, and more.
Ladder and Maintenance Platform: For routine equipment maintenance and servicing.

Applications
The BZD column cantilever crane is widely used across industries:
Factory Workshops: Material handling and process transfer along production lines.
Assembly Lines: Positioning and hoisting of components during mechanical assembly.
Machine Loading/Unloading: Handling of heavy workpieces at machining centers, lathes, milling machines, and similar equipment.
Warehousing: Lifting and loading/unloading of heavy goods in storage areas.
Die & Mold Shops: Hoisting and replacement of dies and molds.
Equipment Maintenance: Lifting operations during equipment servicing and repair.
Docks & Yards: Light-duty lifting operations in open storage yards.
Selection Guide
Light Duty (0.25–1 t / Chain Hoist): Boom length 3–10 m. A chain electric hoist is recommended (lifting speed 6.3–8 m/min) for fast installation, low noise, and high-frequency light-load applications. Reference price: RMB 8,000–20,000.
Medium Duty (2–3 t / Wire Rope Hoist): Boom length 5–15 m. A wire rope electric hoist is recommended (lifting speed 8 m/min, dual-speed optional) for durability in continuous operations and medium-weight workpieces. Reference price: RMB 20,000–40,000.
Heavy Duty (5–10 t / Box Girder + Wire Rope Hoist): Boom length 6–20 m. A box girder structure with electric rotation and electric trolley is recommended, with the wire rope hoist serving as the main hoist — ideal for heavy equipment maintenance and large workpiece lifting. Reference price: RMB 40,000–100,000.
Operating Instructions
Pre-Operation Checks: Inspect the hoist chain/wire rope for damage, verify limit switches are functioning, check the slewing mechanism for abnormal noise, and ensure anchor bolts are tight.
Start-Up: Connect the power supply, confirm the emergency stop button is released, and control hoisting, trolley travel, and boom slewing via the wireless remote control or wired pendant.
Lifting Operations: Keep the load stable during lifting, watch for personnel and obstacles when slewing the boom, and never exceed the rated capacity.
Shutdown & Maintenance: Park the hoist in the designated position and disconnect the power after operations. Periodically inspect slewing bearing lubrication, bolt tightness, and electrical insulation. For chain hoists, regularly check sprocket wear and chain link elongation.

FAQ
Q: What national standards does the column cantilever crane comply with?
A: Design & manufacturing follows GB/T 3811 Crane Design Standard and JB/T 8906 (Slewing Jib Cranes), with safety devices meeting TSG Q7014 requirements.
Q: What is the difference between a column cantilever crane and a wall-mounted jib crane?
A: A column cantilever crane has a freestanding column anchored to the floor, with the boom slewing to cover a fixed workstation — ideal for dedicated station work. A wall-mounted jib crane is installed on a building wall or column side, taking up no floor space and suited for lifting along wall areas. The two differ in structure and application, so the choice depends on your workstation layout.
Q: How much does a BZD column cantilever crane cost?
A: Pricing varies by lifting capacity and boom length: light-duty 0.25–1 t units range from RMB 8,000–20,000; medium-duty 2–3 t units from RMB 20,000–40,000; and heavy-duty 5–10 t units from RMB 40,000–100,000. Final pricing depends on boom length, column height, and any custom features required.
