What is a Single Girder Overhead Crane?
A single girder overhead crane is a specialized material handling system designed to provide three-axis movement across a rectangular facility bay. It is widely recognized as the most cost-effective lifting solution for capacities up to 20 tons and spans up to 18 meters. Commonly used in workshops, warehouses, and material yards, these cranes are typically categorized into LD standard, low-headroom, and LDP types to accommodate different building clearances.
Core Components & How It Works:
- Bridge Girder: The principal horizontal beam that spans the width of your facility. It supports the lifting mechanism and is structurally engineered to carry heavy loads with minimal deadweight.
- End Trucks (End Carriages): Located on both ends of the bridge girder, these trucks house the drive wheels. They travel along elevated runway beams, allowing the crane to access the entire length of the building.
- Lifting Mechanism (Hoist): The electric hoist is mounted on the main girder and handles the actual lifting. We configure our cranes with standard CD (single lifting speed) or MD (double lifting speed) hoists, available in two primary types:
- Wire Rope Hoists: Highly durable and engineered for long-term, reliable performance in heavier applications.
- Chain Hoists: The perfect choice for lower capacity, lighter-duty projects where upfront cost and compact size are the primary deciding factors.
Applications of Single Girder EOT Crane
Due to their compact footprint and efficient performance, our single girder overhead cranes are widely adopted across multiple industries for daily material handling. Key applications include:
- Manufacturing & Fabrication: Moving steel materials and positioning heavy parts for welding or machining.
- Warehousing & Logistics: Streamlining the loading, unloading, and indoor transit of bulk goods.
- Assembly Lines: Providing precise lifting for component installation in automotive and machinery production.
- Maintenance Facilities: Safely lifting heavy motors, pumps, and machinery for routine service and repairs.
Price of Single Girder Bridge Crane
Pricing ranges from $2,000 (1-ton basic setups) to $50,000 (20-ton, wide-span VFD systems). To accurately assess your investment, consider these concrete cost and ROI metrics:
- Upfront Steel Savings: The lower deadweight reduces wheel loads, saving you up to 20% on runway beams and facility structural reinforcement.
- Operating Costs: VFD-controlled hoists reduce brake pad wear by 50% and consume minimal energy (typically 3-5 kW/h), drastically cutting maintenance bills.
- 12-18 Month ROI: By replacing manual lifting and expensive forklift rentals (saving ~$1,500/month), the equipment typically pays for itself in under a year and a half.

Component Details & Engineering Advantages
Built for longevity: How our component design minimizes downtime and maintenance costs.
Main Girder (Fabrication & Finish)
Manufactured from high-strength Q235B/Q355B steel. We use automatic submerged arc welding (SAW) for flawless, deep-penetration joints. Before painting, the entire girder undergoes Sa2.5 shot blasting to completely remove rust, ensuring superior paint adhesion and long-term corrosion resistance, even in harsh environments.
Girder Section (Structural Profile)
Optimized via Finite Element Analysis (FEA), the U-shape or box-girder cross-section maximizes torsional rigidity while minimizing deadweight. Formed in one continuous process, this profile eliminates stress concentration points, ensuring the structure won’t deform under heavy, repetitive loads.
End Beam (End Carriage)
Constructed from rigid rectangular steel tubes. The wheel bores are CNC-machined in a single setup to guarantee absolute alignment. This high-precision engineering permanently solves the “rail gnawing” (wheel-flange wear) problem, ensuring smooth traveling and extending the life of both wheels and runway rails.
Electric Hoist
Features a highly integrated, low-headroom design to maximize your hook path. Driven by a heavy-duty motor with a fully enclosed gearbox and self-adjusting brake, it ensures precise, shock-free load positioning. Its modular construction makes routine inspections and wire rope/chain replacements incredibly fast.
Cable & Festoon System
Power is reliably delivered via flame-retardant, high-flexibility flat cables moving on a galvanized C-track festoon system. Compared to round cables, flat cables provide a far superior bending radius and heat dissipation, completely preventing tangling and internal wire breakage during high-frequency operations.

Single Girder vs. Double Girder Overhead Cranes
One of the most common questions from facility managers is whether to invest in a single girder or a double girder crane system. While both serve the same fundamental purpose, the choice entirely depends on your facility’s dimensions, lifting capacity, and operational frequency.
Why Choose a Single Girder Crane?
- Cost-Effective: Because it requires fewer materials and less complex manufacturing, the upfront cost is significantly lower.
- Lighter Building Loads: The reduced deadweight means less stress on your building’s structural columns and runway beams, saving you substantial money on facility construction or reinforcement.
- Faster Installation: Simplified design allows for quicker assembly and commissioning, minimizing operational downtime.
- The Sweet Spot: It is the absolute best choice for light-to-medium operations, typically lifting up to 20 tons with spans up to 18-20 meters.
When Do You Need to Upgrade to a Double Girder Crane?
You should consider a double girder system only if your operational needs exceed the limits of a single beam:
- Heavy Capacities & Wide Spans: Required for loads exceeding 20 tons or exceptionally wide building spans (over 20 meters) where a single beam would deflect (bend) too much.
- Maximum Hook Height Needed: On a single girder, the hoist hangs underneath the beam. On a double girder, the hoist trolley sits on top of the beams, giving you several extra feet of vertical lifting height.
- Continuous Heavy-Duty Use: Essential for 24/7 continuous production (like steel mills or heavy foundries) requiring A6-A8 duty classes.
Understanding Crane Duty Cycles (Working Class)
A common mistake in crane procurement is looking only at the lifting capacity (tonnage). However, a 5-ton crane used once a week for maintenance is engineered completely differently from a 5-ton crane used 10 hours a day on an assembly line.
To ensure maximum motor lifespan and prevent premature mechanical failure, we strictly follow ISO/FEM standards to configure the correct duty cycle (working class) for your specific application:
- Light Duty (ISO A3 / FEM 1Bm):
- Application: Equipment maintenance bays, pump stations, and motor repair shops.
- Usage: Infrequent lifting, slow speeds, and long idle periods. The crane is mainly used for standby positioning rather than continuous transport.
- Medium Duty (ISO A4 – A5 / FEM 2m):
- Application: General manufacturing workshops, machining centers, fabrication shops, and logistics warehouses.
- Usage: The standard workhorse. Designed for regular, daily use, handling typical loads (often 50% of the maximum capacity) with moderate operating speeds.
Why this matters: Tell us your estimated lifts per hour and working hours per day. Our engineers will size the precise motors, gearboxes, and electrical contactors so you don’t overpay for unnecessary heavy-duty specs, nor suffer from downtime due to under-specced components.
Custom Configurations & Smart Add-ons
While our standard single girder overhead cranes are perfect for normal indoor workshops, many industries require specialized protection and smart controls. We provide fully customized add-ons to meet your exact environmental and safety requirements:
1. Harsh Environment Protections:
- Outdoor Configurations: If your crane operates in an open yard, we upgrade it with marine-grade anti-corrosive epoxy paint, stainless steel fasteners, and IP55+ rain covers for all hoists, motors, and electrical cabinets. Wind speed alarms are also equipped for safety.
- Explosion-Proof (Ex-Proof): For chemical plants, oil & gas facilities, or paint shops, we provide ATEX/IECEx certified explosion-proof components, spark-resistant bronze wheels, and fully sealed control boxes to eliminate fire hazards.
2. Smart & Safe Control Systems:
- Radio Remote Controls: Upgrade from the standard wired pendant to a wireless remote control (featuring top brands like Telecrane or HBC). This allows the operator to walk freely and stay at a safe distance from heavy or hazardous loads.
- Anti-Collision Sensors: If you have multiple overhead cranes running on the same runway, we install laser or photoelectric anti-collision limiters to automatically stop the cranes before they crash into each other.
- Load Weighing Displays: Integrated digital scales on the hook or bottom block provide operators with real-time weight data, preventing dangerous overloading and assisting in material inventory management.
