Internally-Mounted Jib Crane by Kelude Heavy Industry

Product Introduction

The BZN Internally-Mounted Jib Crane (BZN series internally-mounted jib crane), available in models BZN0.5 through BZN2 with rated lifting capacities from 0.5 to 2 tons, is a new material handling solution developed by Kelude Heavy Industry based on its Pillar Jib Crane platform. The BZN jib boom features a hollow structural steel design (KBK rail system) with a built-in travel mechanism equipped with engineering plastic rollers and rolling bearings for low friction and smooth, effortless movement. When paired with a PK series chain electric hoist, it delivers fast and flexible lifting and transport operations.

Product Features

Internally-Mounted Travel Mechanism: Unlike conventional externally-mounted designs, the BZN features a built-in travel mechanism with engineering plastic rollers and rolling bearings, delivering low friction, quiet operation, and smooth, effortless movement.
Hollow Structural Steel KBK Rail: The jib boom uses a hollow structural steel KBK rail system that is lightweight, high-strength, rigid, economical, and durable, while allowing greater vertical hook travel.
PK Chain Electric Hoist Integration: Designed to work with PK series chain electric hoists, with optional two-speed hoisting for frequent short-distance lifting tasks.
Electric or Manual Rotation: The jib slewing can be powered electrically or operated manually to suit user requirements.
270° Effective Coverage: The 270° slewing angle strikes an optimal balance between working range and structural compactness, making it ideal for dense workstations along production lines.
Unified Dimensions: The BZN0.5/1/2 models share identical external dimensions (L5630/R₂5000/H4910), providing a common foundation that simplifies workshop layout standardization.

Operating Principle

The BZN Internally-Mounted Jib Crane operates as follows: the column is fixed to a concrete foundation, and the hollow structural steel jib boom (KBK rail system) is connected to the column via a slewing mechanism. Unlike conventional externally-mounted electric hoists, the BZN's PK chain electric hoist is installed internally, with the travel mechanism housed inside the KBK rail and moving along it on engineering plastic rollers with minimal friction. The jib is driven electrically or manually through a 270° slewing range, allowing the chain hoist to lift loads vertically and transport them horizontally to the desired position.

Product Structure

The BZN Internally-Mounted Jib Crane consists of the following core components:
Column: Fixed to the concrete foundation, serving as the main load-bearing structure.
Jib Boom (KBK Hollow Structural Steel): Built on the KBK rail system with a lightweight, high-rigidity hollow steel structure.
Internally-Mounted Travel Mechanism: Built-in design with engineering plastic rollers and rolling bearings for low friction, smooth travel, and a compact footprint.
Slewing Mechanism: Electric or manual slewing drive enabling 270° jib rotation.
Hoisting Mechanism: PK series chain electric hoist, internally mounted, with optional two-speed hoisting.
Electrical Control System: Pendant station or wireless remote control, including hoisting limit switch.
Safety Devices: Hoisting limit switch, emergency stop button, and more.

Technical Parameters

Note: The BZN0.5/1/2 ton models share identical external dimensions (L=5630mm/R₂=5000mm/R₁=720mm/H=4910mm/h=3000mm) with a 270° slewing angle, differing only in Rated Lifting Capacity. The unified sizing simplifies workshop standardization and foundation construction.

Applications

The BZN Internally-Mounted Jib Crane is ideal for:
Production Line Material Handling: Short-distance, high-frequency, and intensive material transfer and component Lifting.
Machine Tool Loading/Unloading: Workpiece handling for machining centers, lathes, and similar equipment.
Assembly Line: Component assembly and Positioning at workstations.
Warehouse: Loading, unloading, and transport of light goods.
Maintenance Workshop: Hoisting operations during equipment repair.

Selection Guide

BZN0.5 (0.5t / Entry-Level Internally-Mounted Model): 5m slewing radius, equipped with a PK-type Chain Electric Hoist. The internally-mounted travel mechanism runs quietly and smoothly — ideal for precision assembly workshops and light-duty workstations. Reference price: ¥12,000–20,000.
BZN1 (1t / Balanced Model): Identical external dimensions to the 0.5t model, allowing shared foundations and future upgrades without foundation modification. Suitable for medium-weight workpiece handling. Reference price: ¥15,000–30,000.
BZN2 (2t / Maximum Capacity Model): Highest capacity within the unified footprint. Features a PK hoist with Two speed hoisting and 270° slewing coverage — designed for heavier component Lifting and equipment maintenance. Reference price: ¥25,000–50,000.

Operating Instructions

Pre-Operation Inspection: Verify the Chain Electric Hoist chain is intact, the internally-mounted travel mechanism rollers rotate freely, Limit Switches function properly, and Anchor Bolts are Tightening.
Startup & Operation: Connect the Power Supply, use the pendant station or Wireless Remote Control for Hoisting/Lowering, and slew the cantilever via electric or Manual push.
Lifting Operations: Keep the load stable during Lifting, do not exceed the 270° slewing range, watch for personnel and obstacles nearby, and never exceed the Rated Lifting Capacity.
Shutdown & Maintenance: Park the hoist at the designated position and disconnect the Power Supply after work. Perform Periodic Inspection of travel mechanism roller Wear, KBK Rail Joints, chain condition, and Slewing Bearing Lubrication.

FAQ

Q: What does "internally-mounted" mean for the BZN jib crane? How is it different from a regular jib crane?
A: Internally-mounted means the hoist's travel mechanism is built inside the KBK rail (rather than suspended below it), using engineering plastic rollers with Rolling Bearings that run within the rail. Advantages: ① Low friction — smooth, effortless travel; ② Compact design — greater vertical hook travel; ③ Low operating noise — suitable for quiet workshops. The trade-off is a lower capacity ceiling than externally-mounted designs — the BZN series maxes out at 2 tons.

Q: Which standards does the BZN Internally-Mounted Jib Crane comply with?
A: Design & Manufacturing follows GB/T 3811 Crane Design Standard and JB/T 8906 Jib Crane Standard. The KBK Rail System complies with JB/T 8923, the Chain hoist meets JB/T 5317, and safety devices conform to TSG Q7014 requirements.

Q: How much does a BZN Internally-Mounted Jib Crane cost?
A: Pricing varies by Lifting Capacity: BZN0.5 is approximately ¥12,000–20,000, BZN1 is approximately ¥15,000–30,000, and BZN2 is approximately ¥25,000–50,000. Since all three models share identical external dimensions, upgrading from 0.5t to 2t later requires no foundation modification.
