BZD Jib Crane for Efficient Workshop Lifting
Product Introduction
The BZD Internal Slip Ring Jib Crane (also known as BZD Jib Crane / BZD Cantilever Crane) covers models BZD0.25 to BZD5, with a rated lifting capacity of 0.25 to 5 tons. Unlike conventional jib cranes with external cables, this model features an internal slip ring power supply design — power is transmitted through an internal slip ring, allowing the cantilever to rotate continuously through 360° at any angle without any risk of cable entanglement. It serves as a direct upgrade over balancers, offering greater lifting capacity and a longer working radius.

Product Features
Continuous Power via Internal Slip Ring: Unlike conventional jib cranes with external cables, the BZD internal slip ring design transmits power through an internal slip ring, allowing the cantilever to rotate continuously at any angle with no risk of cable twisting or breakage.
Stronger than a Balancer: Compared to balancers (≤500kg), the BZD internal slip ring series offers greater lifting capacity (0.25–5t) and a longer working radius (4–6m), making it a true upgrade for workstation lifting.
Dual-Speed Hoisting: Optional constant/slow speeds (8/2, 4/1 m/min, etc.); slow speed suits precision assembly work.
Rotation at Any Angle: The rotation angle is "arbitrary" — not restricted by limit switches, enabling continuous 360° rotation.
Simple and Reliable Structure: Fixed column design for easy maintenance and long service life.
Non-Standard Design: Lifting capacity, working radius, and lifting height can all be customized to suit specific workstations.
Working Principle
The working principle of the BZD internal slip ring jib crane: the column is anchored to a concrete foundation, and the cantilever connects to the column via a slewing bearing. The key difference from a standard jib crane lies in the power supply — electricity is routed from inside the column to the cantilever through an internal slip ring (collector ring), so even with continuous 360° rotation of the cantilever, the cable never tangles. The electric hoist travels along the cantilever rail, lifts the load vertically during hoisting, and the cantilever slews horizontally to transfer the load to the target position.
Product Structure
The BZD internal slip ring jib crane consists of the following core components:
Column: Fixed to the concrete foundation; the main load-bearing structure of the entire unit.
Internal Slip Ring Assembly (Collector Ring): Mounted at the junction between the column and the cantilever, enabling continuous power transmission from the stationary side to the rotating side.
Cantilever: Connected to the column via a slewing bearing, rotatable at any angle.
Slewing Mechanism: Electric or manual slewing drive.
Hoisting Mechanism: CD1 series wire rope electric hoist, dual-speed optional.
Electrical Control System: Includes hoisting, slewing, and travel controls.
Safety Devices: Hoisting limit switch, emergency stop button.

Note: The BZD internal slip ring model is available in 8 configurations. The "arbitrary" slewing angle means the internal slip ring enables 360° continuous rotation with no angle restrictions. Hoisting speed is available in standard/slow two-speed options, selectable based on working conditions.
Applications
Typical applications for the BZD internal slip ring jib crane:
Industrial workshops: Material handling along production lines.
Assembly lines: Positioning workpieces during assembly.
Machine tool loading/unloading: Transferring materials between multiple machines.
Warehouses and docks: Loading and unloading goods.
Balancer replacement: An ideal upgrade over balancers when greater lifting capacity and longer working radius are required.

Operating Instructions
Pre-operation inspection: Check the electric hoist wire rope, internal slip ring assembly, and limit switches.
Start-up: Connect the power supply and control hoisting and jib slewing.
Lifting operations: The internal slip ring supports continuous rotation. Keep the load stable during lifting and never exceed the rated capacity.
Shutdown and maintenance: Periodically inspect carbon brush wear and contact on the internal slip ring, and lubricate the slewing bearing.
Why Choose Kelude Heavy Industry

FAQ
Q: What is the difference between the internal slip ring jib crane and a standard BZD jib crane?
A: The internal slip ring model transmits power through an internal collector ring, allowing the jib to rotate continuously through any angle with no risk of cable twisting. A standard BZD uses an external cable, which limits the slewing angle (typically ≤360°). The internal slip ring model is better suited for workstations requiring frequent multi-turn rotation, such as circular assembly line stations and multi-station transfer.
Q: Which standards does the BZD internal slip ring jib crane comply with?
A: It complies with GB/T 3811 Crane Design Standard and JB/T 8906 Jib Crane Standard. The internal slip ring assembly is designed per the collector ring provisions of GB/T 2900 Electrotechnical Terminology, and safety devices meet TSG Q7014 requirements.
Q: How much does the BZD internal slip ring jib crane cost?
A: The 0.25–0.5 t models range from ¥10,000–20,000; 1–3 t models from ¥20,000–50,000; and the 5 t model from ¥45,000–80,000. Prices include the internal slip ring assembly, electric hoist, and electrical control system.
