Cranes are indispensable pieces of equipment in industry and construction, they are used to move and lift heavy loads and therefore require a high level of precision and quality standards in their design and installation. Crane rails are a key component in supporting the travel of cranes, and they must meet a range of standards and specifications to ensure the safety, stability and efficiency of the equipment.
Crane rails are usually made of high-strength steel to ensure durability and load capacity. Common steel materials include carbon and alloy steels. These materials need to meet specific chemical composition, mechanical properties and heat treatment standards to ensure their suitability for heavy industrial applications.
The fixed length of steel rail is 9m, 9.5m, 10m, 10.5m, 11m, 11.5m, 12m, 12.5m, and the length of short gauge rail is 6m~8.9m(advanced by 100mm).
The quantity of short gauge rail is negotiated between the supply and demand sides and indicated in the contract, but it should not be more than 10% of the total weight of one batch of order.
Allowable deviation of rail size should be in accordance with the table.
The permissible deviation of straightness and torsion of rails should be in accordance with the table.
Rails are generally delivered according to theoretical weight. After negotiation between supply and demand parties and stated in the contract, it can also be delivered according to the actual weight. The density of steel is calculated according to 7.85g/cm2. Theoretical weight and calculation data of rails are shown in the table.
The contract or order for ordering according to this standard shall include the following contents:
Marking:On the rail waist on one side of each rail, the following clear, raised signs should be rolled out at every 4m interval, with a character height of 20mm~28mm and a raised height of 0.5mm~1.5mm:
On the rail waist of each rail, not less than 0.6m from the end of the rail, at intervals of not more than 6m, the use of hot embossing machine embossed with a clear furnace number mark.
If the hot-embossed furnace number marking is missed or misprinted, it shall be hot-embossed or sprayed again on the rail waist.
