What aspects need to be checked when using the lifting track again?
There is a unique product called 'reused'.Reused rail.In simple terms, reused rail refers to the product that reuses old steel rails, processing the previously damaged ones.Reused rail.It undergoes re-manufacturing without delaying normal use. The application fields of reused rails are numerous; besides being used for railway transportation, they can also be used in areas with special requirements such as heavy truck transportation and lifting platforms.
However, effective inspection work must be conducted for the secondary use of replaced rails, and they can only be used after passing the standards. What aspects need to be inspected?Reused rail.The inspection of reused rails must meet specific standards, and they can only be used if there are no defects. The details are as follows:Reused rail.1. The welding surface should have a smooth, fine scale, no grooves, be continuous, free of wrinkles, and have a gentle metal connection. The welding effect should be seamless, allowing only a few surface pores. Within a range of 3 meters of welding, the pins do not need to be tightened to allow the rail to extend during welding.
1.Reused rail.2. The specific specifications of the welding must be checked to see if they meet technical standards, and whether there are defects, pores, burn-through, weld spatter, gaps, or incomplete welds. If any defects are found, repairs must be made before use.
3. Place the rail on the steel pad, carefully align it to the correct center position, and immediately tighten the pins after alignment.
China has very high reliability performance requirements for the processing of reused rails. Although the replaced rails are not brand new, they are actually only slightly damaged, and reusing them is clean and harmless, which can also save energy and economic costs. However, everyone must remember that when reused rails are damaged to the following extent, they can no longer be used:Reused rail.1. The depth of the guard rail spacer marks exceeds or equals 4mm and cannot be reused.
2. The depth of surface scratches exceeds or equals 2mm and cannot be reused.Reused rail.3. The depth of detached pieces is greater than or equal to 3mm, and the length is greater than or equal to 15mm and cannot be reused.
4. The depth of detached pieces is greater than or equal to 3mm, and the length is greater than or equal to 15mm and cannot be reused.
5. Rails with vertical wear greater than or equal to 8mm and lateral wear greater than or equal to 12mm cannot be reused.
3.脱离掉块深层高于或等于3㎜，长短高于或等于15㎜不可以再利用。
4.脱离掉块深层高于或等于3㎜，长短高于或等于15㎜不可以再利用。
5.竖直磨损高于或等于8㎜,侧边磨损高于或等于12㎜的钢轨不可以再利用。
