Material |
Our Liebherr Lr1550 upper Rollers adopt high-quality 40Mn2 alloy steel. After each batch of 40Mn2 raw materials arrives at the factory, we conduct a comprehensive quality inspection. We verified each item, from chemical composition, hardness, and mechanical properties to appearance and internal defects. Only after confirming that the material meets the standards can it be put into production and processing, ensuring product quality is controlled from the source. | Using ordinary steel as the raw material, the alloy ratio is insufficient. The carbon and manganese content don’t meet the standards, the hardness is uneven, and the wear resistance is poor. It cannot operate in complex environments and is prone to deformation or even fracture. |
Processing Technology |
To ensure the Liebherr LR1550 top roller possesses excellent hardness and superior impact resistance, we implement a professional heat treatment process on the finished product. Enhance comprehensive mechanical properties to ensure the stability and durability of components under complex working conditions.Meanwhile, we apply surface heat treatment, bringing the roller surface hardness to HRC 52-55. This can greatly enhance the wear resistance of the supporting roller. | To save time and costs, ordinary manufacturers of crawler crane undercarriage parts often omit the crucial step of heat treatment.This will significantly reduce the mechanical properties of the crawler crane undercarriage parts, thereby shortening its service life. |
Quality control |
Prior to shipment, we conduct full inspections on our Liebherr LR1550 top rollers, covering surface finish, dimensional accuracy, material hardness and wear resistance.Control quality from the source to bring more benefits to customers. We can provide customers with a full set of inspection reports.Reduce various troubles caused by product quality or installation size issues after customers receive their goods. | Many ordinary manufacturers don’t conduct quality inspections after receiving the goods.If the product quality is not guaranteed, customers may face the risk of product mismatch or substandard product quality after receiving the goods |
