Single Girder Overhead Crane – Professional Material Handling Solution
Product Overview
A single girder overhead crane is an efficient lifting equipment designed for industrial material handling operations. With its compact structure, reliable performance, and cost-effective operation, this crane is ideal for factories, warehouses, and construction sites. Moreover, it offers lifting capacities ranging from 1 ton to 20 tons, making it suitable for diverse applications.
Key Features & Benefits
European Standard Design
Our single girder overhead crane follows modular construction based on FEM/DIN standards, ensuring superior quality and performance. Specifically, the electric hoist runs on the lower flange of main girder, which results in a compact structure with 25-30% height reduction compared to traditional cranes. Additionally, the maintenance-free design guarantees extended service life with minimal operational costs.
High Performance
The single girder overhead crane features smooth operation with soft start/stop functionality for enhanced safety. Furthermore, it provides precise load positioning and control for accurate material handling. In terms of efficiency, the energy-efficient motor system saves over 20% electricity while maintaining low noise operation under 75dB.
Versatile Applications
This overhead crane serves multiple industries effectively:
- Manufacturing plants and machine shops
- Warehouse and logistics centers
- Steel structure workshops
- Construction and assembly facilities

Main Components
Bridge Structure
The main girder of the single girder overhead crane features a box-type welded steel structure with optimized cross-section for maximum strength. Meanwhile, the end beams provide sturdy connections between the main girder and traveling mechanism. In addition, we use Q235B or Q345B steel with comprehensive anti-corrosion treatment to ensure longevity.
Electric Wire Rope Hoist
At the core, the system utilizes a squirrel cage induction motor with IP54 protection rating. Subsequently, the wire rope (6×19 or 6×37 construction) is galvanized for superior durability. Furthermore, the forged alloy steel hook includes a safety latch for enhanced security. Finally, the grooved drum design ensures proper rope guidance and minimal wear.
Traveling Mechanism
The drive system combines a motor, reducer, and wheel assembly for smooth movement. Notably, the forged steel wheels feature hardened tread surfaces for extended service life. Depending on your facility, we can provide standard crane rail or flat rail options for your single girder overhead crane installation.
Electrical Control System
Safety is paramount, therefore our system includes overload limiter, upper/lower limit switches, and emergency stop buttons. Additionally, we use Schneider, Siemens, or equivalent quality components throughout. As a result, the crane benefits from phase failure protection, voltage protection, and thermal overload protection.
Optional Features & Customization
To meet specific operational needs, we offer various upgrade options for your single girder overhead crane:
- Variable Frequency Drive (VFD): Enables smooth acceleration and precise positioning
- Explosion-Proof Design: ATEX/IECEx certified for use in hazardous areas
- Anti-Sway System: Effectively reduces load swing for accurate placement
- Weighing System: Integrated load cell provides real-time weight measurement
- LED Lighting: Significantly enhances visibility throughout the work area
- Warning Devices: Sound and light alarms ensure optimal safety conditions
Installation & Maintenance
Installation Requirements for Single Girder Overhead Crane
Before installation, ensure your workshop crane runway beams have adequate load capacity. Similarly, verify that the power supply matches the crane’s voltage rating (3-phase AC). Moreover, maintain adequate clearance with a minimum of 50mm between crane and building structure. For best results, we strongly recommend engaging a professional installation team.
Maintenance Schedule
Daily Inspection: First, carefully check the wire rope for wear, broken wires, or any damage. Next, thoroughly inspect the hook for cracks or deformation. Then, verify that all limit switches function properly. Finally, examine all bolts and connections for looseness on your single girder overhead crane.
Monthly Maintenance: To begin with, lubricate all bearings, gears, and wire rope according to specifications. Afterward, inspect electrical connections and cables for any issues. Subsequently, test all safety devices and brakes to ensure proper operation. Lastly, clean accumulated dust from motor and electrical components.
Annual Service: During this comprehensive service, qualified technicians perform thorough inspections of all systems. In particular, they conduct non-destructive testing of the main girder structure. If necessary, worn components such as brake pads or wire rope are replaced. Ultimately, they recalibrate all safety devices and load limiters to factory standards.
Safety Operation Guidelines
To ensure safe operation of your single girder overhead crane, always follow these essential guidelines:
✓ Never exceed the rated lifting capacity under any circumstances
✓ Avoid diagonal pulling or side loading, as this can damage equipment
✓ Always keep personnel away from suspended loads during operation
✓ Consistently perform pre-operation inspections on a daily basis
✓ Ensure operators have proper training certification before use
✓ Use appropriate lifting attachments and slings for each load type
✓ Avoid sudden starts and stops to prevent load swing
✓ Never leave loads suspended unattended for safety reasons
