Đường sắt AREMA TR68 là Hiệp hội Kỹ thuật và Bảo trì Đường sắt Hoa Kỳ (AREMA) đã phát triển các tiêu chuẩn cụ thể cho các thành phần cơ sở hạ tầng đường sắt được sử dụng ở Mỹ, bao gồm cả đường ray thép. Đặc điểm kỹ thuật đường sắt TR68 là một trong một số tiêu chuẩn cho đường ray thép được sử dụng ở Mỹ, and it is similar in weight and dimensions to other rails used in the industry. Like other steel rails, the TR68 is made from high-quality steel and designed to withstand the heavy loads and constant wear and tear of railway traffic. It is an important component of railway infrastructure and critical to ensuring the safety and efficiency of rail transportation.
TR68 railway steel rail is a type of rail used in railways for heavy freight and high-speed passenger trains. The TR68 rail has a weight of 68 kilograms per meter and a length of 25 Mét, making it a durable and sturdy rail for long-term use. It is made of high-quality steel, which ensures its strength, Độ bền, and resistance to wear and corrosion. The TR68 rail is an essential component of railway infrastructure, helping to ensure the safe and reliable operation of trains.
The AREMA TR68 rail is a standard profile rail used in North America for heavy haul and high-speed railway lines. It has the following specifications:
– Chiều cao đường ray: 7-5/16 inches or 185.7 Mm
– Rail width at the base: 6 inches or 152.4 Mm
– Rail width at the top: 1-1/4 inches or 74.6 Mm
– Độ dày web: 11/16 inches or 17.4 Mm
– Nominal weight: 68 kilôgam mỗi mét
The TR68 rail is made from high-quality steel, with specific requirements for chemical composition, Tính chất cơ học, and other characteristics to ensure its durability and performance under heavy loads and harsh operating conditions. It is an important component of railway infrastructure and widely used in North America.
Transportation of 25 meters long TR68 rail can be a complex process, and some specialized equipment is needed to handle their size and weight. Here are some common methods used for transporting long rails:
1. Rail carriers or flatbed trucks: Rails can be transported over land by specially designed rail carriers or flatbed trucks. These vehicles need to have a long deck to support the length of the rail, and hydraulic hoists to lift them onto and off the vehicles. These vehicles are typically operated by experienced drivers who are skilled in handling long loads.
2. Railway wagons: Long rails can also be transported by rail using specialized wagons with long flatbeds. The wagons are attached to a locomotive and can be operated on railway tracks. A crane may be used to lift the rails onto the wagons or to unload them.
3. Water transport: When transport by land is not feasible or economical, rails can be transported by water using barges or ships. This method is commonly used for long-distance transport of rails or where rail on-site is not available.
In each of these methods, special care should be taken to secure the rails during transportation to prevent damage or injury to personnel or property. Ngoài ra, all transportation must comply with the local transportation laws and regulations.
