In industrial sites like factories, logistics yards, and construction workshops, many lifting tasks require covering “uneven workspaces”—for example, loading goods from the edge of a warehouse to a truck parked outside, or hoisting components from a production line to an adjacent maintenance area. Traditional single girder gantry cranes with no overhang or double-sided overhang often struggle here: no overhang models can’t reach beyond the support legs, while double-sided overhang models waste space on the unused side. This is where the Yangonyu Single Side Outside Overhang Single Girder Gantry Crane stands out. Designed with a unique single-side external overhang (typically 1-3 meters), this crane delivers targeted lifting coverage, reliable performance (1-12 tons capacity), and seamless adaptation to asymmetric work scenarios. Whether you’re a facility manager dealing with edge-of-site loading or a business owner needing flexible overhang capabilities, this guide will break down everything you need to know about this specialized crane: its design features, core advantages, real-world applications, selection tips, and why it outperforms generic gantry cranes.
What Is the Yangonyu Single Side Outside Overhang Single Girder Gantry Crane?
To understand this crane’s value, let’s start with its definition, structural uniqueness, and how it differs from standard models:
1. Core Design: Single-Side Overhang for Targeted Coverage
The Yangonyu Single Side Outside Overhang Single Girder Gantry Crane features a single main girder (high-strength Q345 steel) supported by two end carriages (legs). Unlike traditional models, it extends a dedicated overhang beam from one side of the main girder—this overhang (customizable from 1.5m to 3m) projects beyond the outer edge of the adjacent support leg, while the other side remains flush with the opposite leg. This asymmetric design ensures the crane can reach areas outside its main footprint (e.g., truck beds, edge-of-warehouse racks) without wasting space on an unused second overhang.
Yangonyu optimizes the overhang structure with reinforced steel plates (12-16mm thick) at the connection between the main girder and overhang beam, distributing load stress evenly to avoid bending. The lifting mechanism—usually a Yangonyu-custom electric hoist (220V/380V)—runs along both the main girder and overhang beam, allowing seamless movement between the “inner workspace” (within the legs) and “outer coverage area” (beyond the overhang).
2. Key Components & Yangonyu-Exclusive Upgrades
Every Yangonyu single side overhang crane integrates durable components and brand-specific enhancements for reliability:
- Main Girder: Box-section steel (instead of standard I-steel) for 30% higher rigidity, reducing deflection when lifting full loads on the overhang.
- Overhang Beam: Heat-treated to resist wear, with a anti-slip trolley rail (Yangonyu patent) that prevents the hoist from derailing during overhang operation.
- Electric Hoist: Yangonyu’s YH series hoist, featuring dual-speed control (8m/min for fast lifting, 2m/min for precise positioning) and IP55 protection for dusty/rainy environments.
- Control System: Wireless remote (100m range) with LCD display showing load weight and hoist position—critical for safe overhang operation where operators may need to stand clear of the extended area.
- Safety Guards: Overload protection (auto-stop at 110% of rated capacity) and overhang limit switch (prevents the hoist from traveling beyond the overhang’s end), compliant with ISO 4301 and CE standards.
Why Choose the Yangonyu Single Side Outside Overhang Single Girder Gantry Crane?
Yangonyu’s asymmetric design isn’t just a structural tweak—it solves pain points that generic cranes can’t address. Here are its standout advantages:
1. Perfect for Asymmetric Workspaces
For sites where lifting needs are concentrated on one side of the crane’s path, this model eliminates waste. For example:
- A warehouse with a loading dock on one side: The overhang can reach directly into truck beds (up to 3m from the warehouse wall), while the other side of the crane stays clear of internal racks.
- A manufacturing plant with a maintenance area adjacent to a production line: The overhang extends over the maintenance zone, allowing the crane to move components from the line to repair stations without repositioning the entire crane.
In tests, Yangonyu’s single side overhang crane reduced “dead space” (unused area around the crane) by 40% compared to double-sided overhang models, maximizing floor space utilization.
2. Higher Load Capacity on Overhang
Generic single side overhang cranes often sacrifice capacity on the overhang (e.g., a 5-ton crane may only lift 3 tons on the overhang). Yangonyu’s reinforced overhang beam and box-section main girder maintain 80-90% of the rated capacity on the overhang:
- A 5-ton Yangonyu crane can lift 4.5 tons on a 2m overhang.
- A 10-ton model handles 8.5 tons on a 2.5m overhang.
This is a game-changer for heavy tasks like loading 4-ton pallets into trucks or hoisting 8-ton machinery parts to an outdoor maintenance pad.
3. Cost-Effective vs. Double-Sided Overhang Models
Double-sided overhang cranes cost 20-25% more than single side models due to the extra overhang structure. Yangonyu’s single side design cuts upfront costs while delivering targeted coverage. Additionally:
- Lower Installation Costs: No need to extend rails for a second overhang—installation takes 2-3 days (same as standard no-overhang cranes), compared to 4-5 days for double-sided models.
4. Yangonyu’s Durability for Heavy Use
Yangonyu tests every single side overhang crane to industrial standards:
- 1,000-cycle load test (lifting full capacity on the overhang) with no structural deformation.
- 500-hour continuous operation test (simulating daily use) with hoist performance unchanged.
Customers report an average service life of 12-15 years—5 years longer than generic single side overhang cranes—thanks to Yangonyu’s high-quality steel and corrosion-resistant coating (galvanized + powder-coated for outdoor use).
Real-World Applications of Yangonyu Single Side Overhang Cranes
Yangonyu’s model has proven its value across industries with asymmetric lifting needs. Below are three typical use cases:
Case 1: Food Distribution Warehouse (U.S.)
A large food warehouse in Illinois needed to load frozen pallets (3-4 tons each) from a rack line (10m from the wall) to trucks parked 2m outside the warehouse. A standard no-overhang crane couldn’t reach the trucks, while a double-sided model would block the adjacent pedestrian aisle. The warehouse installed a 5-ton Yangonyu crane with a 2.5m overhang:
- The overhang reached directly from the racks to the truck beds, eliminating the need for a forklift transfer (saving 15 minutes per truck).
- Daily loading capacity increased from 20 trucks to 28 trucks (40% improvement).
- Zero accidents in 3 years, thanks to the overhang limit switch and load display.
Case 2: Automotive Parts Factory (Germany)
A German auto parts factory produced engine blocks (6-7 tons each) on a production line, with a testing area 2m outside the line’s edge. A generic single side overhang crane could only lift 4 tons on the overhang—insufficient for the engine blocks. Yangonyu customized a 10-ton crane with a 2m overhang (8.5-ton capacity on overhang):
- The crane moved engine blocks directly from the line to the testing area, cutting transfer time by 50%.
- Yangonyu’s dual-speed hoist allowed precise placement of the engine blocks onto test stands (error ≤3cm).
- The factory reduced labor costs by 20% (no need for a second team to assist with lifting).
Case 3: Construction Material Yard (China)
A Shanghai construction yard stored steel bars (5-8 tons per bundle) in a yard, with a delivery truck zone 3m from the storage racks. A traditional gantry crane would require the trucks to park within the crane’s legs—impossible due to narrow access roads. A 12-ton Yangonyu crane with a 3m overhang solved the problem:
- The overhang reached over the road to load bars directly from racks to trucks.
- The crane’s weatherproof design (IP55 hoist, galvanized steel) withstood Shanghai’s rainy summers.
- The yard reduced truck waiting time from 1 hour to 25 minutes, improving supplier satisfaction.
How to Select the Right Yangonyu Single Side Outside Overhang Crane
To get the most out of your investment, follow these 5 steps to choose the correct model:
Step 1: Define Overhang & Load Requirements
- Overhang Length: Measure the distance from the crane’s support leg to the farthest area you need to reach (e.g., 2m from leg to truck bed = 2m overhang). Yangonyu offers 1.5m, 2m, 2.5m, and 3m options—avoid over-sizing (a 3m overhang costs 15% more than 2m if not needed).
- Overhang Load Capacity: Calculate your heaviest load for the overhang (e.g., 4-ton pallets = choose a crane with ≥4.5-ton overhang capacity). Yangonyu’s technical team can provide a “capacity-overhang chart” (e.g., 5-ton crane: 4.5t@2m overhang, 4t@2.5m overhang).
- Main Girder Span: Measure the distance between the two support points (e.g., warehouse walls, rail ends) for the crane’s main body—Yangonyu offers spans from 6m to 20m.
Step 2: Match to Your Environment
- Indoor vs. Outdoor/Semi-Outdoor:
- Indoor (e.g., warehouses): Standard model with IP54 hoist and powder-coated steel.
- Outdoor/Semi-Outdoor (e.g., yards, docks): Yangonyu’s “Weather-Resistant Package” (galvanized steel, IP65 hoist, rain cover for electrical components).
- Fixed paths (e.g., between warehouse and loading dock): Rail-mounted (Yangonyu’s KR series rails, 20mm thick).
- Flexible paths (e.g., construction yards): Rubber-tired (battery-powered, 0-90° steering) with Yangonyu’s anti-slip tires for gravel surfaces.
Step 3: Choose the Right Hoist & Controls
- Electric Hoist (Yangonyu YH series): For frequent use (5+ lifts/day) or heavy loads (3-12 tons). Choose 220V for small workshops, 380V for industrial sites.
- Manual Hoist (optional): Only for occasional use (1-2 lifts/day) or no electricity—note: manual hoists have no overhang speed control, so avoid for precise tasks.
- Controls: Wireless remote is mandatory for overhang operation (Yangonyu’s YC series remote with emergency stop button on the receiver, in case the remote fails).
Step 4: Verify Safety & Compliance
Ensure the crane meets your region’s standards:
- Global Markets: CE (Europe), OSHA (U.S.), ISO 4301 (international).
- China Market: GB/T 3811-2008 (crane design) and GB 6067.1-2010 (safety rules).
- Additional Safety: Ask for Yangonyu’s “Overhang Safety Kit” (includes load cell display, anti-sway device, and overhang beam vibration sensor) for high-risk tasks (e.g., outdoor lifting in wind).
Step 5: Leverage Yangonyu’s Customization & Support
Yangonyu excels at tailored solutions—don’t settle for off-the-shelf models:
- Custom Overhang: Need a 3.5m overhang? Yangonyu can design it with reinforced steel (additional cost applies, but no loss of capacity).
- After-Sales Service: Choose Yangonyu’s “Global Maintenance Plan” for 24-hour repair support (available in 50+ countries) and 2-year warranty on the main girder/overhang beam (1-year on the hoist).
- References: Ask Yangonyu for case studies in your industry (e.g., “automotive parts factories using 10-ton single side overhang cranes”) to validate performance.
Installation & Maintenance Tips for Yangonyu Cranes
Proper installation and care ensure your Yangonyu single side overhang crane operates safely for years:
Installation Best Practices (Yangonyu Recommended)
- Rail-mounted: Install Yangonyu KR series rails on a concrete foundation (≥20cm thick) with laser alignment (error ≤1mm/m). The rail under the overhang leg must be reinforced with an extra concrete pad (30cm thick) to support overhang loads.
- Rubber-tired: Ensure the ground is level (slope ≤2°) and compacted—Yangonyu provides a ground pressure chart (e.g., 10-ton crane = 0.3MPa ground bearing capacity).
- After mounting the main girder to the legs, use a Yangonyu alignment tool to check that the overhang beam is horizontal (error ≤0.5mm/m). An unlevel overhang causes the hoist to drift, risking load drops.
- Test Run (Critical for Overhang):
- No-Load Test: Run the hoist along the entire main girder and overhang beam 3 times—check for smooth movement and limit switch activation at the overhang end.
- Load Test: Lift 50% of rated capacity on the overhang, hold for 5 minutes; then lift 100% capacity, move it along the overhang, and lower slowly. Record deflection (should be ≤L/500, where L = overhang length) using Yangonyu’s deflection ruler.
Maintenance Schedule (Yangonyu Guidelines)
Common FAQs About Yangonyu Single Side Overhang Cranes
Q1: Can the overhang be adjusted after installation?
A: No—Yangonyu’s overhang beam is welded to the main girder for structural integrity. To change the overhang length, you’ll need to replace the entire overhang beam (contact Yangonyu for custom replacement parts).
Q2: What’s the maximum wind speed for outdoor overhang operation?
A: Yangonyu recommends stopping overhang lifting when wind speed exceeds 10 m/s (36 km/h). For windy regions, ask for the “Wind-Resistant Overhang Kit” (includes wind sensors that auto-lock the hoist at high winds).
Q3: How does this crane compare to Yangonyu’s double-sided overhang model?
A: Use the single side model if you only need coverage on one side (lower cost, less space). Choose double-sided if you need overhang on both sides (e.g., loading/unloading trucks on two sides of a warehouse). The single side model is 20% cheaper and has 30% lower maintenance costs.
