Product Introduction
Crane rails that meet GB standards are manufactured through strict quality control, selection of suitable steel materials, and professional rolling processes. They are used to build crane rail systems and achieve special rails for smooth movement of cranes.
QU80 rail steel is a steel specially used for crane rails. Its size design enables it to withstand the huge load of the crane and provide a stable running surface for the crane wheels. Materials such as U75V and U71Mn are usually used. In addition to the carbon content, the strength and hardness of the rails can be improved. The addition of alloying elements manganese and vanadium makes the rails have good toughness and wear resistance. They can easily withstand the impact and friction during the operation of the crane, protecting the safe and smooth operation of the crane.

FAQ
1. Compared with other types of crane rails, what are the advantages?
The theoretical weight of QU80 rail is about 63.69kg per meter, and its rail height, bottom width, head width and waist thickness are 130mm, 130mm, 80mm and 32mm respectively. Such size and weight design enables it to withstand a weight of 50-100 tons, and its carrying capacity is at an upper-middle level. Compared with specifications such as QU70, QU80 can withstand heavier loads and is suitable for cranes with larger lifting weights; and compared with larger models such as QU100, it can be used in some places with certain space and cost restrictions under the premise of meeting certain load requirements, and has better adaptability.
2. What are the key points for installing GB QU80 crane rails?
Foundation treatment: Before installation, ensure that the installation foundation is firm and flat, and can withstand the load of the rails and cranes during operation. Carry out necessary tamping, pouring concrete and other treatments on the foundation to ensure the strength and stability of the foundation.
Track laying: Lay the rails accurately according to the design requirements, and control the spacing, horizontality and straightness of the tracks. Use professional measuring tools to ensure that the track spacing error is within the allowable range, the horizontal deviation does not exceed a certain value per meter (such as 0.5mm), and the straightness deviation meets the relevant standards.
Fixed method: Use suitable fixings to firmly fix the rails on the foundation. Common fixing methods include pressure plate fixing, bolt fixing, etc. The fixings should have sufficient strength and durability to prevent the rails from loosening and displacement during operation.
3. How to maintain GB QU80 crane rails?
Regular inspection: Regularly check the wear of the rails, including the rail head, rail waist, rail bottom and other parts, and use calipers and other tools to measure the wear. When the wear reaches a certain extent (such as the rail head wear exceeds 10% of the original size), it is necessary to consider replacing the rails; check the connection parts of the rails, such as whether the fishtail plates and bolts at the joints are loose or damaged, and tighten or replace them in time.
Cleaning and lubrication: Regularly clean the debris, dust, oil, etc. on the surface of the rails to keep the rail surface clean and reduce the wear between the wheels and the rails; apply lubricants to the sliding parts of the rails, such as the contact between the wheels and the rail surface, to reduce the friction coefficient, improve operating efficiency, and also help reduce wear.
Correction and adjustment: If the track is found to be deformed or displaced, make corrections and adjustments in time. Use professional correction tools, such as jacks, track adjusters, etc., to restore the track to the correct position and state.
