Powering a Manufacturer: Dongqi Crane Supplies 4 Complete Systems (Excluding Main Girders) for Thai Crane Production Facility

In 2020, a leading Thai shipyard and crane manufacturer partnered with Dongqi Crane for a specialized project. While the client fabricated the main girders locally, Dongqi delivered everything else—the complete crane systems including end carriages (bridge structure), QDX hoist trolleys, and full electrical controls. This collaboration showcases our ability to serve as a true engineering partner, providing the high-precision components that define crane performance.

Project Specifications:

  • Quantity: 4 Units
  • Model: QDX European Standard Double Girder
  • Capacity: 5 Tons | Span: 24 Meters | Lift Height: 10 Meters
  • Power: 415V / 50Hz / 3Ph
  • Dongqi Scope: Complete end carriages, QDX hoist trolleys, full electrical systems & controls
  • Client Scope: Main girders

Completed End Carriage – The Bridge Foundation

This end carriage represents the structural integrity of the crane bridge. Machined precisely to accommodate wheels and drives, it ensures smooth travel across the 24-meter span. The robust fabrication you see here is designed to handle years of heavy-duty operation in a demanding port maintenance environment.

Weatherproof Protection for Ocean Freight

Shipping to tropical Thailand requires serious preservation. Here, completed end carriages are wrapped in heavy-duty waterproof tarpaulin. This protects against humidity, salt spray, and condensation during the entire sea voyage, ensuring the machinery arrives in the same pristine condition as when it left our factory.

The QDX Hoist Trolley – The Heart of the System

This is the complete hoist trolley assembly, featuring our European-style compact design. It integrates the wire rope hoist, motor, and gearbox into a single, efficient unit. By supplying this fully assembled, we minimized on-site work for our client and ensured the core lifting mechanism arrived ready for integration.

Export-Ready Packaging – Hoist in Custom Crate

Hoist trolleys contain sensitive gears, motors, and electrical components. Standard shipping is not sufficient. Each unit is securely fastened inside a custom-built, reinforced wooden crate, engineered to prevent shifting during transport and protect against contaminants. This attention to detail ensures every component arrives ready for installation.
