Construction Machinery

Hydraulic transmission and servo proportional control technology have become the core driving forms of modern construction machinery, thanks to their unique technical advantages including high power density, outstanding structural rigidity, stable linear motion output, as well as excellent heat dissipation and cooling performance. Compared with traditional mechanical transmission modes, hydraulic systems can flexibly realize stepless speed regulation and linear drive, featuring simple structure, convenient layout and easy automatic control. Therefore, they are widely applied in almost all mainstream construction machinery equipment.

At present, hydraulic control systems are fully adopted for the working devices and core functional systems of various construction machinery. The applicable equipment covers concrete pump trucks, excavators, wheel loaders, truck cranes, crawler bulldozers, wheel cranes, self-propelled scrapers, motor graders, vibratory rollers and other engineering equipment. Hydraulic technology penetrates the whole machine control logic, including steering system traveling drive system and brake system, realizing flexible, stable and efficient operation of construction machinery under complex working conditions.

Construction machinery usually operates in variable and harsh environments such as earthwork excavation, road construction and foundation treatment, requiring hydraulic systems to feature high load resistance, strong impact resistance and good motion response accuracy. Our company has long focused on the research, matching, maintenance and technical service of hydraulic servo and proportional systems for construction machinery. We provide one-stop professional services including hydraulic system debugging, fault overhaul, servo valve and proportional valve calibration, hydraulic component maintenance and spare parts replacement for various engineering machinery equipment, effectively solving common problems such as weak driving force, unstable walking, insensitive steering and insufficient braking performance caused by hydraulic system aging and component failure, ensuring long-term stable and efficient operation of construction machinery.
