INTRODUCTION

The single girder overhead crane is a type of bridge crane that uses one main girder to support the hoisting mechanism (electric hoist) which travels along the girder. Its main components include the main girder, end carriages, electric hoist, crane travelling mechanism, and electrical control system. This crane features light self-weight, low headroom, compact footprint, and smooth operation. Lifting capacity typically ranges from 1 ton to 20 tons (some models up to 32 tons). It is widely used for material handling in workshops, warehouses, and outdoor storage yards.

APPLICATION SCENARIO

1.Manufacturing (Machinery, Automotive, Metalworking): Used for loading/unloading workpieces, die/mold changing, semi-finished product transfer, and assembly line material supply. Ideal for lifting needs in auto parts, machine tool processing, and steel product industries.

2.Warehousing, Logistics & Freight Centers: Used for fast loading/unloading, stacking, inbound/outbound operations, and short-distance transportation in warehouses, distribution centers, and freight yards, greatly improving space utilization.

3.Energy, Power & Petrochemical Industry: Used for equipment maintenance (e.g., turbines, transformers, motors) and material lifting in power plants, substations, and petrochemical plants. Explosion-proof versions are available.

4.Emerging & Special Fields (Aerospace, New Energy, Precision Manufacturing): Used for assembly and handling of large or precision components such as rocket parts, wind turbine blades, and photovoltaic equipment, meeting high precision, cleanliness, or special environmental requirements.

ADVANTAGES

1.Compact structure, low headroom design: The integrated compact design of girder and hoist effectively reduces the crane’s own height, allowing higher space utilization in workshops, especially those with limited headroom.

2.Light self-weight, economical and energy-saving: Compared with double girder cranes, the single girder structure greatly reduces dead weight, lowers building load requirements, and reduces energy consumption during operation, saving investment and operating costs.

3.Smooth operation, precise positioning: Optional frequency conversion control and intelligent control systems enable smooth start/stop and millimeter-level accurate positioning, meeting fine handling requirements.

4.Strong adaptability, flexible configuration: Supports either suspended or seated installation. Various operation modes available, such as wireless remote control, cabin control, or pendant control. Customizable for explosion-proof, high-temperature resistance, magnetic lifting, etc.

5.Easy maintenance, high reliability: Modular design with maintenance-free or long-life components. Daily inspection is convenient, low failure rate ensures long-term continuous operation.

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.
