Our client from Turkey, a renowned manufacturer of truck cranes, is specialized in the R&D and production of high-end hydraulic lifting equipment. Its truck crane products are widely applied in heavy-duty working conditions such as construction, logistics, and municipal engineering. To enhance the rotational stability and service life of the equipment, the customer sought a highly reliable customized solution for slewing bearings.
Adapt to large-tonnage truck cranes: Meet the rotational load-bearing requirements for 10-ton+ heavy-duty lifting.
High rotation precision: Ensure the stability and safety of lifting operations.
Adapt to complex Turkish working conditions: Feature dust-proof, impact-resistant, and long-life characteristics.
Customized installation dimensions: Achieve perfect adaptation based on the equipment structure.
Xuzhou Langley Machinery Equipment provided customized large-module slewing bearings for the customer:
Product Selection: Three row roller slewing bearings for the truck crane application, the gear ring with precision
Process Upgrade: Adopted 42CrMo quenched and tempered steel, undergoing overall quenching + tooth surface high-frequency quenching. This improved load-bearing capacity by 30% and extended service life by 50%.
Sealing Optimization: Equipped with a dual labyrinth seal structure, effectively coping with dusty and outdoor working conditions to reduce maintenance costs.
Fast Delivery: From drawing confirmation to finished product delivery, 25-35 days were required to meet the customer’s mass production needs.
After the installation of Langli slewing bearings, the truck crane operated smoothly without jamming during rotation, and maintained stable load-bearing performance under heavy-duty conditions, fully meeting the customer’s design requirements. The customer has listed Langli as a core supplier, placed bulk orders for the full range of truck crane products, and plans to expand subsequent in-depth cooperation.
