INTRODUCTION

A flexible, compact, and highly efficient lifting solution designed for independent floor mounting. Provides 360-degree continuous rotation for localized material handling in areas without external support structures.

APPLICATION SCENARIO

[1] Workstations and Assembly Cells – Lifting components onto machines or production lines for repetitive tasks.

[2] Maintenance and Repair Shops – Hoisting engines, gearboxes, pumps, and heavy parts for service.

[3] Loading Docks – Assisting in loading/unloading heavy goods from trucks or pallets.

[4] Warehouses – Moving heavy items from shelves or racks within the jib’s coverage area.

[5] Manufacturing Cells – Serving individual machines such as lathes, mills, or presses with dedicated lifting.

ADVANTAGES

[1] Full Rotation Coverage – Manual or electric rotation up to 360° for flexible positioning.

[2] Electric Hoist Efficiency – Faster lifting and lowering compared to manual chain hoists.

[3] Independent Installation – No building support needed; stands on its own foundation.

[4] Compact Footprint – Small base while covering a large circular area.

[5] Durable and Reliable – All‑steel construction with sealed bearings and electric hoist for long service life.

Six core advantages

Full Scenario Coverage

Nucleon covers over 20 product categories including ladle cranes, multi-purpose cranes, intelligent cranes, overhead/portal cranes, RTG, RMG, deck cranes, portal cranes, girder launchers, yacht cranes, KBK, and jib cranes. From steel smelting to port handling, bridge construction to ship equipment, Nucleon provides one-stop lifting solutions. Whether standard models or extreme-condition customizations, Nucleon possesses mature technical expertise and proven track records, saving customers from dealing with multiple suppliers.

Military-Grade Quality Standards

We use high-strength steel from Baosteel/Ansteel for key structural components, with 100% NDT inspection and one-clamp CNC gantry machining. Every machine undergoes 120% dynamic load and 125% static load tests before delivery, with continuous operation verification under extreme conditions. Even in 24/7 continuous casting plants, -40°C arctic ports, or high-temperature humid ship cabins, our cranes maintain millimeter-level precision and zero-drift stability—quality that stands the test of time.

Extended Longevity & Low Maintenance Cost

Our main girders are FEA-optimized and double-submerged arc welded, with a design life of ≥30 years. Key bearings are lifetime lubrication-free, and hardened travel wheels extend wear cycles by 3 times. Core components feature modular quick-change interfaces with spare parts commonality exceeding 80%. Annual maintenance costs are reduced by 40%~60%, saving millions in lifecycle operating expenses — truly "invest once, benefit long-term."

Energy Efficiency Leader

Our entire series comes standard with IE5 permanent magnet synchronous motors + energy feedback VFD drives, achieving 25%~35% comprehensive energy savings. Single-motor operation under light loads and adaptive speed control reduce electrical waste by over 30%. High-strength steel lightweight design cuts deadweight by 15%~20%, lowering workshop load requirements. A single ladle crane station saves over RMB 150,000 in electricity costs annually, helping customers achieve green and low-carbon production.

Ultimate Safety Redundancy Design

Our hoisting mechanism comes standard with dual brakes + mechanical overspeed switch + triple limit switches, featuring multiple redundant interlocks to prevent load dropping and over-traveling. Large products use box girder torsion-resistant structures, remaining stable even in level 8 gusty winds. Optional intelligent safety monitoring systems detect anomalies in load, skew, wind speed, etc., with automatic alarms and shutdowns. Overall safety redundancy coefficient > 2.0, maintaining zero crane safety incidents for many consecutive years.

Deep Customization & Full Lifecycle Service

We provide complete front-end support from site survey and mechanical simulation to civil review, delivering custom drawings within 2 weeks, with non-standard lead times only 5~7 days longer than standard products. We establish lifelong digital dossiers for customers, warning of end-of-life components 3 months in advance. Our full lifecycle services cover installation training, regular inspections, and remote O&M. With customer repeat purchase rates exceeding 85% for five consecutive years, we are a trustworthy long-term partner.

FAQS

01What are the foundation requirements for installing a free-standing jib crane?

A: A free-standing jib crane requires a solid, reinforced concrete foundation to ensure structural stability and safety. The exact depth and dimensions of the foundation depend on the crane’s lifting capacity and arm length. We provide detailed foundation drawing templates for every order.

02Can the rotation angle be customized if I don't need a 360-degree rotation?

A: Yes. While 360° rotation is standard, we can install mechanical rotation limiters to restrict the slewing angle to 180°, 270°, or any custom range to fit your workspace layout and avoid obstacles.

03What type of electric hoist can be fitted on this jib crane?

A: You can choose between an Electric Chain Hoist (recommended for higher precision and compact design) and an Electric Wire Rope Hoist (ideal for high-frequency or heavier duty lifting). Manual chain blocks are also available upon request.

04Can this jib crane be installed outdoors?

A: Yes. For outdoor installations, we offer weatherproofing options including rain covers for the motor/hoist, anti-corrosion marine-grade painting, and IP55/IP65 electrical protection.

05How do I choose between a Single Girder Gantry Crane and a Column Jib Crane?

Column Jib Crane: Ideal for localized, circular work areas (360° sweep) over short distances (e.g., a single workstation or CNC machine). Gantry Crane: Better suited for long-distance linear travel across a larger warehouse or outdoor yard to move heavier, wider loads.
