Excavators operate in some of the toughest environments—construction sites, mining areas, and infrastructure projects where dust, vibration, and long working hours are part of daily operation. To keep these machines running smoothly, stable transmission of power, signals, and hydraulic media is essential. This is where slip rings play a vital role.
In most hydraulic excavators, gas-liquid slip rings are responsible for transmitting high-pressure hydraulic oil during continuous rotation. Installed between the upper structure and undercarriage, these slip rings must handle constant movement without leakage or performance loss. High-strength stainless steel construction and reliable sealing are key to ensuring durability and long service life, especially in outdoor and heavy-duty applications.

Smaller and more compact excavators increasingly rely on electric slip rings to handle control signals and power transmission. Stable signal performance is critical for throttle control, sensors, and machine coordination. Designed to withstand vibration and mechanical shock, JINPAT electric slip rings help reduce unexpected downtime and maintenance frequency in demanding job sites.
Integrated slip rings offer an efficient solution for machines that require multiple transmission types. By combining hydraulic, pneumatic, and electrical functions into a single unit, integrated slip rings simplify installation and improve overall reliability. This is particularly valuable for modern excavators and modified machines used in specialized applications.

With extensive experience in construction machinery applications, JINPAT provides slip ring solutions designed for durability, adaptability, and long-term performance. By focusing on real working conditions and customer needs, JINPAT helps equipment manufacturers and operators achieve stable operation and lower lifecycle costs.
