Product Features
Low Headroom (+290 mm): The low-headroom design increases the lifting height by 290 mm compared to standard configurations, making it the ideal choice for low-profile factory buildings and retrofit projects in older workshops—no need to raise the roof.
KBK Hollow Profile Rail: Utilizes standard KBK hollow profile rail, offering low dead weight and extremely low travel resistance for effortless manual operation—one person can easily achieve precise positioning.
PK Chain Hoist with Two-Speed Hoisting: Standard equipment includes a PK-type chain electric hoist with two-speed hoisting (8/2, 4/1, etc.), enabling slow-speed precise positioning and high-speed efficient lifting.
Easy Manual Slewing: The extremely lightweight design allows the jib to be rotated manually without effort, ideal for light-duty, high-frequency lifting tasks.
Compact Footprint: The column-plus-cantilever structure occupies only 1 m² of floor space, perfect for production line workstations with limited space.
Foundation-Free Installation: The 125–250 kg models can be secured with chemical anchors, eliminating the need for large concrete foundations and cutting installation time by 50%.
Working Principle
The working principle of the KBK pillar jib crane is as follows: The column is fixed to a concrete foundation, and the KBK hollow profile rail, serving as the jib main girder, is connected to the column via a slewing mechanism. The PK-type chain electric hoist is mounted on the KBK rail and travels horizontally along it. During lifting, the chain hoist raises the load vertically, and the jib is manually rotated to transfer the load horizontally to the target position. Thanks to the low travel resistance of the KBK rail, the operator can easily push the hoist and load to the desired workstation, enabling rapid coverage of lifting tasks within the work area.
Product Structure
The KBK pillar jib crane consists of the following core components:
Column: Manufactured from high-quality structural steel and secured to the concrete foundation with anchor bolts, serving as the primary load-bearing core of the entire unit.
Jib Main Girder: Uses KBK hollow profile rail as the crane main girder, offering a high lifting capacity relative to its dead weight, extended outreach, and low travel resistance.
Slewing Mechanism: Manual slewing mechanism with a simple structure and flexible operation.
Hoisting Mechanism: PK-type chain electric hoist with two-speed hoisting for high reliability.
Electrical System: Chain hoist control box with upper and lower hoisting limit controls.
Ladder and Maintenance Platform: Facilitates routine maintenance and servicing.

Applications
KBK pillar jib cranes are widely used across industries:
Mechanical Manufacturing: Lifting and transferring components between production line workstations.
Automotive Assembly: Assembling and handling parts on the assembly line.
Shipbuilding: Hoisting and positioning small fittings.
Warehouses & Docks: Loading, unloading, and moving light materials.
Laboratories: Installing and positioning precision instruments and equipment.
Machine Tool Loading/Unloading: Handling heavy workpieces for machining centers, lathes, and similar equipment.
Modern Production Lines: Serving as a standalone emergency hoisting solution on highly automated lines to keep production flowing without interruption.
Selection Guide
KBK0.0125 (125kg): Radius 3m, manual rotation. Ideal for light component handling between workstations and assembly tasks. Reference price: ¥6,000–12,000.
KBK0.25 (250kg): Radius 3m, manual rotation. Suitable for loading/unloading medium-weight workpieces and assembly operations. Reference price: ¥8,000–18,000.
KBK0.5 (500kg): Radius 3m, manual rotation. Designed for heavy part hoisting and equipment maintenance. Reference price: ¥10,000–25,000.
Operating Instructions
Pre-Operation Inspection: Check the chain electric hoist chain for integrity, verify limit switches are functioning, listen for abnormal noise from the slewing mechanism, and confirm anchor bolts are secure.
Start-Up: Connect the power supply, use the pendant controller for hoisting/lowering, and manually push the jib and hoist to the desired position.
Lifting Operations: Keep loads stable during lifting, watch for personnel and obstacles when rotating manually, and never exceed the rated capacity. Two-speed operation: slow speed for precise positioning, fast speed for efficient lifting.
Shutdown & Maintenance: Park the hoist in its designated position and disconnect power after operations. Periodically inspect KBK rail joints, chain wear and sprocket condition, and slewing bearing lubrication.

FAQ
Q: What low-clearance factory scenarios is the KBK flexible jib crane best suited for?
A: The KBK low-headroom design gains an extra 290mm of lifting height over standard solutions, making it ideal for: ① Retrofitting older factory buildings—installable even with under 4m ceiling height; ② Repurposed buildings—warehouses converted to workshops, underground spaces; ③ Adding lifting points to existing production lines—installing hoisting points above current equipment. It offers the lowest installation threshold of any lifting solution for confined spaces.
Q: What's the difference between the KBK flexible jib crane and a standard BZD column-mounted jib crane?
A: The KBK flexible jib crane uses a hollow-profile KBK rail as its main girder, offering light weight and low rolling resistance with a smaller lifting capacity (125–500kg)—ideal for frequent light-duty handling. The BZD column-mounted jib crane uses an I-beam or box-girder construction with a higher lifting capacity (0.25–5t), suited for medium-to-heavy hoisting tasks. The two differ in applicable tonnage, rail system, and operational flexibility.
Q: Which design and safety standards does the KBK flexible jib crane comply with?
A: Design & manufacturing comply with GB/T 3811 Crane Design Standard and JB/T 8906 (Jib Crane standard). The KBK rail system meets JB/T 8923 (Electrical control equipment for light-duty cranes), the chain electric hoist complies with JB/T 5317 (Chain electric hoist standard), and safety devices meet TSG Q7014 requirements.
Q: How much does a KBK pillar jib crane cost?
A: Pricing varies by lifting capacity and radius: 125kg models range from ¥6,000–12,000, 250kg from ¥8,000–18,000, and 500kg from ¥10,000–25,000. Final pricing depends on radius, lifting height, and any custom requirements.
