CR175 crane rail belong to ASTM A759-2000 standard, it is widely used in South America, we can produce it by order, the quantity can be talked.

CR175 is a type of crane rail used for overhead cranes and other heavy-duty applications. It is designed to support heavy loads and provide a smooth surface for the movement of cranes and other equipment. The “CR” designation stands for Crane Rail, while the number 175 refers to the weight of the rail in pounds per yard.

CR175 rail is typically made from high-strength steel, and they have a specific profile that conforms to industry standards. They are often installed on concrete or steel sleepers and fastened to the sleepers with bolts or other types of fasteners.

The exact dimensions and properties of CR175 rail can vary somewhat depending on the specific manufacturer and country of origin. However, they are generally designed to meet strict quality standards and provide reliable performance under a wide range of conditions.

If you have any specific questions about CR175 crane rail or their usage, feel free to ask and I’ll do my best to provide you with relevant information.

Drawing of CR175 crane rail

ASTM A759-2000 standard CR175 crane rail is a rail used for cranes and other heavy machinery equipment. Here are some basic information about CR175 crane rail:
1. Material: CR175 crane rail is usually made of high-quality alloy steel, which has high strength and hardness.
2. Dimensions: The standard dimensions of the CR175 rail are 152.4 millimeters wide, 152.4 millimeters high, and weigh approximately 86.8 kilograms per meter, with a length of 12 meters.
3. Features: ASTM A759-2000 standard CR175 crane rail is designed with a special shape and structure, which can withstand heavy loads and high-speed operation, and has good wear resistance and impact resistance. In addition, it also has good welding and processing performance, making it easy to install and maintain.
4. Application: ASTM A759-2000 standard CR175 rail is widely used in various heavy machinery and equipment fields, including cranes, gantry cranes, bridge cranes, etc. in industries such as ports, mines, metallurgy, chemical, power, and construction.
Overall, ASTM A759-2000 standard CR175 crane rail is a high-performance track rail suitable for various heavy-duty and high-speed running cranes and other heavy machinery equipment. As a Chinese supplier, we can provide high-quality CR175 rail and other types of rail products to meet the needs of different customers.

Standard EN 13674 - 1:2003 consists of two main parts:

− qualification test and acceptance tests

Qualification tests are some other tests that were previously carried out, as for example, fracture toughness. Acceptance tests characterize the properties of the prescribed tests, which ensure production of high quality rails, and testing requirements of railway administration.

Quality of rails is based on measured values of hardness, by which they introduced new labels for steel rails.

Qualifying tests

Qualification testing must be conducted at least one in five years and the major

changes in technology, production rails. Additional testing residual stresses are carried

out on all types of steel rails every two year maximum, provided that the longitudinal

strain rate in the rails can amount to up to 250 MPa.

The prescribed qualifying examination is the following:

− fracture toughness

− fatigue crack growth rate

− fatigue testing

− residual stress in rail foot

− variation of centre line

− tensile strength and elongation

− segregation

− other qualification requirements

Acceptance tests

Within acceptance testing is carried out a series of laboratory tests such as:

− chemical composition (the maximum content of the following elements: H, O, Al, V, N and oligo elements)

− microstructure (increasing x 500)

− degree of decarburizing charred layer (allowed up to 0.25 mm)

− purity of steel (especially the presence of oxide)

− macrostructure (Baumann test)

− hardness

− tensile strength

Other acceptance testing rails are:

− dimension tolerances

− criteria (control template)

− inspection requirements / tolerances for to internal quality and surface quality

Internal state is examined ultrasound in a continuous process control, and includes at least 70% of the head and at least 60% web.

- Standard of UIC 860 V: 1996 - prescribed four types pearlite steel rails in the range of tensile strength from 700 to 1300 MPa.

- Standard EN 13674 - 2003, provides seven types pearlite steel hardness in the range 200 to 390 HBV, types steel in accordance with EN 13674, based on the values of hardness (R 200, R 220, R 260, R 260 Mn, 320 Cr, 350 HT, 350 LHT).
