Case Study: Dongqi Crane Delivers a Customized Lifting System to a Pakistani Partner
Following the finalization of our supply contract, Dongqi Crane was honored to welcome our esteemed Pakistani client for a critical factory acceptance visit. This engagement served as a key project milestone, allowing the client to conduct a thorough on-site inspection of their custom-manufactured equipment and reinforce the collaborative partnership established during our initial negotiations.


Validating Quality: A Collaborative Inspection Process
The client’s visit was an exercise in quality assurance and partnership. Their delegation engaged in a detailed technical walkthrough of our manufacturing processes, witnessing the precision behind their order.





The inspection focused on core components and assembly lines, culminating in the successful acceptance testing of the completed Explosion-Proof QB (Double Girder) and LB (Single Girder) Overhead Cranes. This hands-on verification provided tangible confirmation of the equipment’s build quality, performance, and strict adherence to the agreed technical specifications.
A Comprehensive Lifting Solution Portfolio
The order comprises a carefully selected mix of cranes designed to address various operational needs within the client’s facility. Below is a detailed breakdown of the customized solutions.
| Product Model | Capacity | Span | Lifting Height (H) | Key Characteristics & Targeted Application |
|---|---|---|---|---|
| QB10T-21.336M H12.19M | 10 Ton | 21.336 m | 12.19 m | Heavy-Duty Workhorse for Hazardous Areas. Two units of this robust crane are designated for main production zones with explosive atmospheres (e.g., chemical processing), safely handling core loads over a wide span. |
| QE10+10T-20.5M H14.5M | 10+10 Ton | 20.5 m | 14.5 m | Enhanced Lifting Flexibility & Efficiency. This model is engineered based on our standard QD double girder design, featuring an added auxiliary trolley and dual hooks. It is ideal for handling long, bulky loads (like steel beams or pipes) requiring two lifting points, or for simultaneous, independent lifting operations in large work areas, significantly improving workflow efficiency. |
| QB5T-21.64M H12.19M | 5 Ton | 21.64 m | 12.19 m | Wide-Span Handling with Safety. Provides reliable, explosion-proof material transfer for medium-duty applications across extensive workshop areas. |
| LB5T-9.144M H12.19M | 5 Ton | 9.144 m | 12.19 m | Flexible & Economical Safety Solution. Ideal for supporting tasks like maintenance or packaging within classified hazardous zones, offering a cost-effective explosion-proof option. |
| LB4T-8M H12M | 4 Ton | 8 m | 12 m | Versatile Light-Duty Handling. Suited for tool handling and component feeding in smaller hazardous work cells. |
| LB1T-8M H12M | 1 Ton | 8 m | 12 m | Precision Utility Lifting. For light assembly and precise positioning tasks in environments requiring explosion-proof equipment. |
| QDX2T-12.19M H7.9M | 2 Ton | 12.19 m | 7.9 m | Compact and Efficient General Lifting. The QDX series, standing for Electric-Driven Small Bridge Crane, is designed for efficient light-capacity lifting in standard workshop environments, complementing the primary material flow system. |
