LH Type Double Girder Overhead Crane and Steel Structure
SEVENCRANE recently completed a customized LH Type Double Girder Overhead Crane project for a customer operating in the Middle East and African market. The project included not only a 10-ton LH double girder overhead crane but also a complete steel structure support system, runway beams, rails, columns, conductor bars, and installation guidance services. By providing a comprehensive solution, SEVENCRANE successfully helped the customer maximize the limited space available in the workshop while ensuring efficient and safe lifting operations.
The equipment was manufactured within 20 working days and shipped under FOB Ningbo terms. This project highlights SEVENCRANE's engineering capabilities in delivering customized lifting solutions for facilities with strict space and structural limitations.
Project Background
The customer is a product supply and service development company involved in industrial projects across the UAE and Mozambique markets. The lifting equipment was intended for installation inside a workshop where space and headroom were extremely limited.
Initially, the customer requested a quotation for a 5-ton single girder overhead crane. After reviewing the proposal, the customer considered the price too high and temporarily suspended the project. To help reduce costs, SEVENCRANE recommended alternative lifting solutions, including a simple gantry crane configuration. However, the customer still did not move forward with the purchase.
Two months later, the customer's company owner contacted SEVENCRANE and expressed interest in visiting the factory. During the visit, our engineering team carefully reviewed the project requirements and analyzed the workshop dimensions. Based on the actual site conditions, SEVENCRANE developed a customized solution that maximized lifting performance while fitting within the restricted building dimensions.
Although several rounds of price negotiations followed, the customer ultimately recognized the value of the customized engineering solution. During a second factory visit, the purchasing manager finalized the technical details, negotiated the commercial terms, and paid a USD 500 deposit on-site to confirm the order.
Technical Configuration
LH Type Double Girder Overhead Crane
- Model: LH
- Capacity: 10 Tons
- Span: 18.13 m
- Lifting Height: 4 m
- Working Duty: A3
- Control Method: Wireless Remote Control
- Power Supply: 380V, 50Hz, 3 Phase
Complete Supporting Structure
The project also included:
- 100 m runway rails (50×30 mm)
- 100 m runway beams (HN396×199×7×11)
- 18 support columns (HN396×199×7×11)
- 50 m bus bar system (10 mm²)
- Anchor bolts and connection hardware
- Installation guidance services
The column spacing was carefully designed according to the customer's workshop layout, ensuring structural stability and optimal crane travel performance.
Customized Design for Limited Workshop Space
One of the biggest challenges of this project was the limited available headroom inside the facility.
To maximize lifting capacity within the restricted height, SEVENCRANE equipped the crane with a low-headroom electric chain hoist. This configuration significantly increased the effective lifting height compared with conventional hoist arrangements.
The customer also required reliable and internationally recognized electrical components. Therefore, the crane was equipped with:
- SEVENCRANE motors
- Chint and Delixi electrical components
- Delixi transformers
- Inovance frequency inverter
- Zhuoyue cables
- Nanjing Yuding wireless remote-control system
These premium components ensure long-term reliability, smooth operation, and simplified maintenance.
Comprehensive Service Support
In addition to equipment supply, SEVENCRANE provided installation guidance for the entire system. Special attention was given to runway beam installation and conductor bar bracket welding. The 50×30 mm rail support steel was pre-welded to the runway beams before shipment, reducing installation time at the project site.
All required bolts, anchor bolts, and connection accessories were included in the delivery package, allowing the customer to complete installation efficiently.
Why the Customer Chose SEVENCRANE
Despite several months of negotiations and repeated price discussions, the customer ultimately selected SEVENCRANE because of our ability to provide a complete customized solution rather than simply supplying a crane.
Our engineering team invested significant time in understanding the customer's workshop limitations and developing a practical design that optimized lifting performance. The ability to supply the crane, steel structure, electrical systems, and installation support from a single source greatly simplified project execution.
The successful order has established a strong foundation for future cooperation and demonstrates the advantages of choosing a professional manufacturer for complex lifting projects.
Conclusion
This project showcases the flexibility and engineering advantages of the LH Type Double Girder Overhead Crane. By combining a customized low-headroom crane design with a complete steel structure support system, SEVENCRANE delivered an efficient material handling solution perfectly suited to the customer's limited workshop environment.
Through professional engineering, quality manufacturing, and comprehensive service support, SEVENCRANE continues to help industrial customers worldwide achieve safer, more efficient, and more productive lifting operations.
