The NMH-European type single girder gantry crane project in the Dominican Republic represents a successful example of customized lifting solutions for modern construction and infrastructure development. Designed specifically for precast beam handling, this project demonstrates how European-standard gantry crane technology can replace traditional lifting methods while significantly improving efficiency, safety, and operational control.
Project Background
The customer is an end user operating in both the construction industry and the crane rental equipment sector, with a new production facility dedicated to manufacturing precast concrete beams. Previously, the company relied on truck cranes to handle beam lifting and transportation. However, this method involved high operating costs, low efficiency, and limited safety control.
To optimize production efficiency and establish a stable, long-term lifting solution, the customer decided to invest in gantry crane systems. After technical communication and project evaluation, the final solution was confirmed as two units of NMH-European type single girder gantry cranes, designed to operate synchronously for beam lifting.

-
Application Scenario
The NMH-European type single girder gantry crane system is mainly used for lifting, transporting, and positioning precast beams in the new factory. Compared with traditional truck crane operations, the gantry crane solution provides:
-
Continuous production flow
-
Higher lifting precision
-
Lower operational cost
-
Reduced labor dependence
-
Safer handling of heavy precast components
The synchronized dual-crane configuration enables safe lifting of long and heavy beams without structural deformation, making it ideal for precast concrete production lines.
Project Communication Process
The project development followed a professional and structured communication process:
-
March 13, 2025: Initial contact with case sharing from previous Dominican gantry crane projects.
-
March 14, 2025: Phone discussion confirming self-use project and civil foundation preparation needs.
-
April 2025: Technical confirmation, design optimization, and solution validation.
-
June 11, 2025: Project restarted and updated to 10T gantry crane solution.
-
June 17, 2025: Commercial negotiation completed, discount finalized, and PO confirmation scheduled.
-
Follow-up discussions included future projects involving two 30T gantry cranes and one 100T gantry crane.
Conclusion
This project highlights the value of the NMH-European type single girder gantry crane as a modern replacement for traditional lifting methods in precast beam production. With European-standard design, synchronized operation capability, premium electrical systems, and customized structural solutions, the gantry cranes provide a stable, efficient, and safe lifting platform for large-scale construction projects.
By replacing truck crane operations with fixed gantry systems, the customer gains long-term operational efficiency, lower operating costs, improved safety control, and a scalable lifting infrastructure that supports future production expansion.
