Construction Machinery

As the construction machinery industry advances toward electrification, intelligence, and high-end upgrades, excavators, loaders, cranes, and concrete machinery face heavy-duty conditions, harsh environments, and demanding long-life reliability challenges. Critical assemblies such as engines, hydraulic systems, transmissions, slewing bearings, and support structures require ever-higher large-torque tightening precision, heavy press-fitting capability, and key parameter traceability. Conventional methods can no longer meet the industry's demands for high-quality, long-service-life, reliable manufacturing.

Leveraging high-precision, high-consistency, flexible, and intelligent product advantages across three core business lines — servo press-fitting, intelligent tightening, and automatic feeding — Lixing delivers one-stop assembly solutions from standalone equipment to fully integrated lines for the construction machinery industry. Our solutions are widely applied in wheel bearing press-fitting, pin-shaft press-fitting, oil seal pressing, bushing insertion, slewing bearing press-fitting, engine key bolts, hydraulic pump valve bolts, transmission bridge bolts, slewing support bolts, crawler plate large-torque tightening, as well as automated feeding of screws, pins, and circlips. Covering critical assembly processes across powertrain, transmission, hydraulic, and travel core assemblies, we help construction machinery OEMs achieve high-quality heavy-duty equipment assembly — significantly improving overall machine reliability and durability consistency while driving construction machinery manufacturing toward intelligent, digital, high-quality development.
