INTRODUCTION

What is this?

The HD model single girder overhead crane is a cost-effective lifting solution featuring a single main beam structure with an electric hoist or wire rope trolley. The hoist travels along the bottom flange of the I-beam or box-section girder, achieving precise lifting and handling of light to medium loads such as machinery parts, raw materials, finished goods, tools, and assembled components. If your workshop has standard building height and you need a reliable, budget-friendly overhead crane for daily lifting tasks under 20 tons, this product is designed for you.

Why choose an HD single girder overhead crane over a double girder overhead crane?

Compared to double girder overhead cranes, the HD single girder solution offers four core advantages:

First, lower investment cost – simplified single beam structure reduces manufacturing cost by 30%-40%, ideal for budget-limited projects.

Second, faster installation – lighter self-weight with simpler rail requirements, installation and commissioning completed within 5-7 days.

Third, greater headroom – the single girder occupies less overhead space, providing higher effective lifting height under the same building clearance.

Fourth, easier maintenance – fewer components, fewer failure points, and modular hoist design result in lower daily maintenance costs.

Get reliable overhead lifting with a more economical investment.

What can we do for you?

We understand that every customer has different building structures, different capacity requirements, and different working areas. Therefore, we offer flexible customization options: lifting capacity from 1 ton to 20 tons; span from 7.5 meters to 22.5 meters; control options of pendant, remote radio, or cabin; single speed, dual speed, or VVVF speed control optional. Whether your workshop is for machining, assembly, or warehousing, we can match the most suitable span and lifting height.

Unsure? Don't know?

Not sure what lifting capacity suits your daily workload? Don't know what span fits your workshop width? No problem. Just tell us: your building clearance height, your workshop span, and the maximum weight of the objects to be lifted.

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.
