BZD Pillar Jib Crane for Industrial Lifting
Product Introduction
The BZD Series Pillar Jib Crane (BZD series external slip ring column jib crane) is a pillar-mounted jib crane designed for use with an electric hoist. Available in models BZD0.25 to BZD5, with a rated lifting capacity of 0.25 to 5 tons, it consists of a column, slewing jib, jib drive unit, and electric hoist. The column base is secured to a concrete foundation with anchor bolts. A motor drives a gearbox to rotate the jib, while the electric hoist travels back and forth along the I-beam of the jib. The BZD jib crane features a simple structure, easy operation, minimal floor space footprint, and a wide working range, making it ideal for material handling in industries such as machinery manufacturing, automotive, and shipbuilding.

Product Features
External Slip Ring Power Supply: Equipped with an external slip ring conductive system, the jib can rotate through any angle without cable entanglement, making it ideal for applications requiring a wide slewing range.
Simple Structure: The pillar-mounted design secures the column to the ground foundation, with the jib connected via a slewing bearing for a compact and reliable structure.
Space-Saving: The column occupies minimal floor space while the jib covers a large working area, maximizing space utilization.
Easy Operation: The electric hoist is controlled via wireless remote control or pendant, and jib slewing is electrically driven, allowing the operator to manage all functions from the ground.
Electric Hoist Integration: Pairs with an electric hoist (chain or wire rope type), providing three degrees of freedom—lifting, horizontal travel, and slewing—to cover the entire working area.
Customization Available: Jib length and column height can be tailored to meet specific requirements for workshop height, working range, and lifting capacity.
Working Principle
The working principle of the BZD series external slip ring jib crane: The column base is secured to a reinforced concrete foundation with anchor bolts, and the slewing bearing and external slip ring conductive device are mounted at the top of the column. A motor drives the gearbox to rotate the jib around the column (0.6 to 0.75 r/min), enabling the jib to cover any angle in the horizontal plane. The electric hoist is suspended from the I-beam of the jib and travels horizontally along its length. The hoisting mechanism of the electric hoist provides vertical lifting of the load. The combined motion of these three directions—jib slewing, hoist horizontal travel, and hoist vertical lifting—allows the load to be positioned anywhere within the working area.
Product Structure
The BZD series external slip ring jib crane consists of the following core components:
Column: Fixed to the concrete foundation, supporting the entire system. The BZD5 model features a reinforced column.
Slewing Bearing: Connects the column and jib, carrying the jib and load weight while ensuring smooth rotation.
External Slip Ring Conductive Device: Supplies power to the electric hoist, allowing rotation at any angle without cable tangling.
Jib (I-Beam): Serves as the runway rail for the electric hoist; its length determines the working radius.
Jib Drive Unit: Motor and gearbox drive the jib rotation at 0.6 to 0.75 r/min.
Electric Hoist: Chain hoist or wire rope hoist, providing lifting and horizontal movement of the load.

External vs. Internal Slip Ring
BZD series jib cranes are available with either an external or internal slip ring:
External Slip Ring (models on this page): The slip ring is mounted on the outside of the column, offering a simple conductive structure that is easy to maintain. It allows slewing at any angle, making it suitable for most standard applications. Available in models BZD0.25 to BZD5, with lifting capacities from 0.25t to 5t.
Internal Slip Ring (Continuous Rotation): The slip ring is built into the column, providing a cleaner appearance and supporting continuous, unlimited rotation. This type is ideal for special applications requiring multiple full turns. Typically available for lifting capacities up to 3t.
Selection Advice: For standard conditions, the external slip ring type offers the best value. Choose the internal slip ring type if your application requires continuous multi-turn rotation.
Operating Instructions
Installation Foundation: The column base is secured to the concrete foundation with anchor bolts. The depth and strength of the foundation must meet the equipment load requirements.
Pre-Operation Checks: Verify that the cantilever slews freely, the electric hoist operates correctly, and the slip ring power supply is stable.
Start-Up: Slew the cantilever to the working position, position the electric hoist above the lifting point, and lift the load.
Lifting Operations: Never exceed the rated lifting capacity. Keep personnel clear of the area beneath suspended loads. The slewing speed is 0.6–0.75 r/min; avoid sudden starts or stops.
Maintenance: Periodically inspect the slewing bearing lubrication, slip ring wear, electric hoist wire rope/chain condition, and anchor bolt tightness.

FAQ
Q: What is the difference between the BZD external slip ring jib crane and the internal slip ring version?
A: The external slip ring is mounted on the outside of the column, offering a simple structure, easy maintenance, and slewing at any angle. It suits most standard applications (0.25–5t). The internal slip ring is built into the column, providing a cleaner appearance and continuous unlimited slewing for special applications. For standard conditions, the external slip ring type is the more economical and practical choice.
Q: Can the jib length of the BZD jib crane be customized?
A: Yes. The standard maximum slewing radius (R2) is listed in the technical parameters table. The jib length and column height can be customized to suit your workshop dimensions and operational needs. Note that a longer jib requires a corresponding reduction in rated lifting capacity to ensure structural safety.
Q: Which manufacturing standards does the BZD jib crane comply with?
A: The design and manufacturing follow the JB/T 8906 industry standard for Jib Cranes. The column and jib structure are designed in accordance with GB/T 3811 Crane Design Standard, the slewing bearing is selected per JB/T 2300, and the safety devices comply with TSG Q7014.
Q: What is the price range for the BZD jib crane? What are the foundation requirements?
A: The BZD0.25–0.5t is approximately ¥5,000–9,000; the BZD1t is approximately ¥8,000–15,000; the BZD2–3t is approximately ¥15,000–25,000; and the BZD5t is approximately ¥25,000–40,000. Foundation requirements: concrete grade of C25 or higher, with foundation depth and reinforcement calculated based on the equipment load. Anchor bolt positions must be installed according to the foundation drawing.
