C70B Open Top Railway Wagon

C70B open Top railway wagon

Overview

For the rapid increase rail freight capacity to address the constraints of national economic development "bottleneck" problem, in the organization of the Armament Department of Transportation, the company developed a 70t class C70 Universal railway wagon , by optimizing the body structure, the use of 450MPa high strength of atmospheric corrosion resistant steel and other measures, cycling load increased over the C64 railway wagon 10t, load capacity increased by 16.7%, according to the daily loading of 100,000 per day can increase the transport capacity 1,000,000 tons, an increase of transport capacity 360 million tons; Meanwhile, under the existing station, line conditions to CDB 5000t train station to save a lot of renovation costs. The car developed signs of success achieved by the railway truck 60t to 70t grade level upgrading, but also laid the foundation for other technical upgrading of various types of trucks, while the development of the car but also for China's railway GM trucks made of stainless steel laid the technical foundation.

To further improve the corrosion resistance and critical body parts reliability, extend service life and maintenance cycle of railway vehicles, reducing vehicle maintenance and overhaul costs, improve vehicle efficiency and improve vehicle to achieve comprehensive economic and competitive rail freight whole lifetime target capacity, according to the transport truck loaded [2006] No. 130 document requested by the Ministry of Transportation equipment, our company take the lead, Beijing Jiaotong University, Harbin welding Institute, EPRI gold of the iron, TISCO, Baosteel Group, Shanghai Industrial Co., Ltd. and Australia, Beijing February, Meishan, Xi'an Rolling Stock Works, Baotou North-ups, Qiqihar East Lake depot and many other units jointly established the new truck 70t class to extend the maintenance cycle and supporting technology research group on The new TCS stainless steel corrosion resistance welding process, molding process, fatigue reliability; vehicles running gear, coupler buffer device, the braking system reliability and supporting the use of key parts of life surveys, improvements and other research projects.

70t-class combination of new trucks to extend the maintenance cycle and supporting technology research and C80B railway wagon mature experience, I am in the C70 Universal railway wagon on the proposed new universal stainless steel railway wagon 70t class design, completed in May 2006 prototype vehicle the trial, in June 2006 to July Sifang Rolling Stock Research Institute presided over the completion of the static strength test body, body impact test.

The main purpose The car is for the Chinese standard gauge railway use, mainly for shipping coal, ore, building materials, machinery and equipment, steel and timber cargo common rail vehicles, except to meet manual handling, but also to adapt dumper other mechanized unloading operations, and can adapt to the requirements of the library thawing.

The main features

c70b universal railway wagon

C70B and C70 railway wagon railway wagon with the same technical parameters and inheritance C70 railway wagon main structural features, based on the body for better corrosion resistant stainless steel, bogie, braking, and other systems using slow and hooks basically the same components C70 railway wagon car, some parts of the original on the basis of improved and optimized to improve reliability, reduce repair and maintenance costs.

One-floor, side walls, end walls, doors and other goods with stainless steel contact parts to improve the corrosion resistance of the vehicle, depot repair cycle is extended to two years, factory repair period be extended to 12 years, the life of the vehicle can be achieved cut the body free exchange.

Two pairs of welded structures were refined design to optimize the joint form, better adapted to automated welding operations, improve the quality of welding and structural reliability.

3 braking system in accordance with the idea of using a standardized modular design, improved manufacturing requirements and the level of commercialization braking systems and components can be realized interchangeable parts, improved operational reliability of the braking system.

4 main bearing beam chassis parts are made of high yield strength of 450MPa and a new medium-strength steel beams, contained material, light weight, adapt tonne heavy haul trains transport requirements.

5 railway wagon interchangeability meet existing requirements, the main components with the existing railway wagon interchangeable, easy maintenance and repair.

Application

C70B Universal railway wagon has been on the road 13 railway wagons full manufacturers for transfer of technology, and have carried out a car-like vehicle prototype, production finished vehicles into the use of the whole road test in 2007. The car with the increased load capacity and 60t trucks considerable line-level dynamic performance, not only greatly improve the transport capacity, but also save a lot of stations, lines, bridge reconstruction funds, has obvious economic and social benefits. By using new materials such as stainless steel, not only to meet the cancellation minor, depot repair requirements extend to two years, and factory repair period be extended to 12 years to 30 years to extend the life of the requirements, reduced vehicle repair and maintenance costs, improved vehicle efficiency and the use of turnover, has a good application and promotion prospects. 

Model C70B open top wagon is specially designed to transport coal on railway gauge 1435mm, this type of railway wagon is mainly used for transport the coal, mining stones, construction material, machinery, equipment and etc. This wagon can be manual loading and discharge, also it can be discharged by the dumpper.

Loading capacity: 70t,

Tare weight: ≤23t,

Volume: 77 CBMm ,

Design speed: 120 km/h.
