Product Features
Bridge Crane Replacement: The BZZ Heavy-Duty Jib Crane costs only 30–50% of a Bridge Crane of equivalent capacity. It requires no crane runway girder or Crane Rail, and can be installed in existing factory buildings without structural reinforcement — delivering an exceptional return on investment.
Slewing Bearing + Variable-Section Cantilever: This design supports loads from 1 to 10 tons, with a Lifting Height of 2.5 to 16 meters and a working radius of 7 to 12 meters.
360° Rotation: Full 360° Slewing capability provides coverage far beyond that of fixed-column designs. The BZZ10 model achieves a working radius of up to 10 meters.
Dual Operation Modes: Choose between pendant control or Wireless Remote Control. For larger working radii, Wireless Remote Control is recommended.
Minimal Foundation Costs: Only a single foundation pit is required — no crane runway girders, rails, or corbel columns needed. This cuts civil construction costs by over 60%.
Non-Standard Customization: Lifting Capacity, working radius, Lifting Height, and foundation type can all be tailored to your specific operating conditions.
Working Principle
The working principle of the BZZ Series Heavy-Duty Pillar Jib Crane is as follows: The Column is securely fixed to a concrete foundation using Anchor Bolts. The Cantilever, featuring a variable-section design, is connected to the Column via a Slewing Bearing. An electric Slewing mechanism rotates the Cantilever around the Column. The mounted Electric Hoist travels horizontally along the Cantilever's rail. During lifting, the Electric Hoist raises the load vertically; the Cantilever then rotates to transport the load horizontally to the desired position, covering material handling needs across a large work area. The rotation angle is unlimited, and Operation Mode can be selected as either pendant control or Wireless Remote Control.
Product Structure
The BZZ Series Heavy-Duty Pillar Jib Crane consists of the following core components:
Column: Fixed to the concrete foundation, featuring a reinforced structure to handle heavy loads.
Cantilever: Variable-section design, providing a Lifting Height of 2.5 to 16 meters and a working radius of 7 to 12 meters.
Slewing Bearing: Large-diameter bearing ensuring smooth rotation of the heavy-duty Cantilever, with unlimited rotation angle.
Slewing mechanism: Electric rotary drive for smooth Cantilever rotation.
Hoisting mechanism: Wire rope hoist with selectable hoisting speed (8m/min or 0.8m/min).
Electrical Control System: Pendant control or Wireless Remote Control, including hoisting Limit Switch control.
Safety Devices: Hoisting Limit Switch, Emergency Stop Button, and more.

Typical Applications
The BZZ series heavy-duty jib crane is suitable for the following applications:
Metallurgical Industry: Heavy material handling in steel mills and smelting workshops.
Railway: Maintenance and hoisting of railway equipment.
Docks & Ports: Cargo loading, unloading, and transfer.
Machinery Manufacturing: Inter-process transport and assembly of heavy components.
Warehousing & Logistics: Loading, unloading, and stacking of heavy goods.
Alternative to Bridge/Gantry Cranes: Ideal for applications requiring wide coverage but with limited budget — lower initial investment, higher cost efficiency.
Selection Guide
BZZ1~BZZ2 (1–2t / replaces 3–5t bridge cranes): Radius 7–12m, hoisting speed 8m/min, investment approximately 40% of a comparable bridge crane. Suitable for medium-duty workpiece handling. Reference price: ¥30,000–60,000.
BZZ3~BZZ5 (3–5t / replaces 5–10t bridge cranes): Radius 7–12m, hoisting speed 8m/min, investment 35–45% of a bridge crane. R₁ = 1.5–1.7m effectively reduces blind spots. Reference price: ¥50,000–120,000.
BZZ7~BZZ10 (7–10t / replaces 10–20t bridge cranes): Radius 5–10m, hoisting speed 0.8m/min (slow speed for heavy loads). Foundation load approximately 60% less than a bridge crane. Reference price: ¥100,000–250,000.
Operating Instructions
Pre-Operation Inspection: Check the electric hoist wire rope for damage, verify limit switches are functioning properly, listen for abnormal noise from the slewing mechanism, and ensure anchor bolts are tightened.
Start-Up: Connect the power supply and use the pendant station or wireless remote control to operate hoisting, trolley travel, and jib slewing.
Lifting Operations: Keep the load stable during lifting. Watch for personnel and obstacles in the area when slewing the jib. Never exceed the rated lifting capacity. For heavy loads, the slow speed setting is recommended.
Shutdown & Maintenance: After operations, park the hoist in the designated position and disconnect the power. Perform periodic inspection of slewing bearing lubrication, weld seams on the variable-section boom, bolt tightness, and electrical insulation.

FAQ
Q: Can the BZZ heavy-duty jib crane really replace a bridge crane?
A: The BZZ can fully replace a bridge crane in the following scenarios: ① Fixed-point operations where workstations are concentrated within a 5–12m radius; ② Limited investment budgets where you want to save on the civil works required for a bridge crane; ③ Older factory buildings without crane runway girder design or with insufficient headroom below the girder. The BZZ costs only 30–50% of a bridge crane but covers over 80% of typical workstation needs. If workpieces need to travel extensively along the length of the workshop, a bridge crane remains the only option.
Q: What is the difference between the BZZ heavy-duty jib crane and the standard BZD column cantilever crane?
A: The BZZ is the heavy-duty series with a lifting capacity of 1–10 tons and a radius of 7–12 meters. It uses a slewing bearing and tapered boom structure, making it suitable for large-capacity, wide-coverage lifting and capable of replacing bridge cranes. The BZD is the light-duty series with a lifting capacity of 0.25–5 tons, designed for fixed-point lifting of small to medium loads. The BZZ offers lower investment and higher efficiency compared to bridge cranes.
Q: Which standards does the BZZ heavy-duty jib crane comply with? How do they differ from standard jib crane requirements?
A: The BZZ series complies with GB/T 3811 Crane Design Standard, JB/T 8906-2014 Jib Cranes, and GB/T 6067 Safety Regulations for Lifting Appliances. Since the BZZ is a heavy-duty series (1–10 tons, 7–12m radius), the design additionally follows GB 50256 Code for Construction and Acceptance of Electric Device Installation Engineering for Cranes, and the slewing bearing is selected per JB/T 2300 Slewing Bearings standard to ensure safety and reliability under large capacities and wide radii.
Q: How much does a BZZ heavy-duty jib crane cost?
A: Pricing varies by lifting capacity and radius: BZZ1~BZZ2 approximately ¥30,000–60,000; BZZ3~BZZ5 approximately ¥50,000–120,000; BZZ7~BZZ10 approximately ¥100,000–250,000. Final pricing depends on non-standard requirements such as radius, lifting height, and special features.
