Ballast hopper wagon manufactured for UAE railway project

Ballast Hoppers Exported to UAE

As a partner of CRCC, CRRC Taiyuan has specially developed a batch of special ballast hopper wagons for its railway project under construction in UAE (United Arab Emirates) to transport and lay ballast.

At the end of July 2020, after the trial production of the first hopper wagon is completed, the company has carried out a series of verification tests on the trial production sample vehicle, including the rain leakage test of the control room, the opening and closing test of the bottom door, the static brake shoe pressure test, the clearance passing test, and the single-vehicle test, all of which meet the requirements of relevant test specifications.

Although the raw materials and working hours were affected to some extent during the epidemic period, the company overcame the difficulties and completed the production of this batch of hopper wagons on time with quality and quantity guaranteed, and delivered them to the client on schedule.

Details of These Ballast Hoppers

This batch of ballast hopper wagons is designed to run on standard 1435mm gauge railways in UAE.

Their middle ballast unloading doors adopt pneumatic mechanical transmission mechanism, and the unloading bottom doors at sides adopt the mechanical transmission mechanism with pneumatic as the main and manual as the auxiliary.

Ballast hopper wagon made for the CRCC and CCECC joint railway project in UAE.

Notable Features:

  • The Q450NQR1 high strength weathering steel is used for the main section steel and plate of the wagon body, which ensures its high strength and long service life;
  • The track beam is made of TJ / CL 35 standard hot rolled 310 Z-shape steel with yield strength of 450MPa;
  • The one end of the underframe is equipped with a passing platform, railing, and a handrail, and the other end is equipped with a reversible crossover plate, which is convenient for people to travel between the control rooms of two adjacent wagons;
  • The side walls adopt a plate column structure, which is composed of side plate, side column, and upper side beam. The side plate is made of a 4mm thick high strength steel plate, and the upper side beam is made of 120mm*60mm*4mm high strength cold-formed rectangular steel pipe, and the side column is made of 5mm thick hat hyperboloid high strength cold-formed section steel;
  • By optimizing the cross-section shape and geometric position of the reinforcing beam of the middle and side hopper plate, it can work together with the traction beam of the car body to improve the transmission of the longitudinal force of the hopper and reduce the stress level of the joint.
