Heavy industrial construction machinery equipment such as loaders, excavators, cranes, tunnel boring machines, marine machinery, rescue trains, and aerial work platforms all integrate components capable of 360° rotation. During operation, they largely require various slip rings to transmit current, voltage, gas, liquid, and various signals.
For example, conductive slip rings in cranes are mainly installed on the center of rotation for the exchange of power and signals between the upper and lower parts of the crane. Conductive pneumatic-hydraulic combined slip rings in excavators and loaders are installed between the cab and the rails to transmit signals, pneumatic pressure, hydraulic pressure, and kinetic energy, enabling the excavator to rotate 360° for operation.
The application environments for conductive slip rings in construction machinery are mostly harsh and complex, including high and low temperatures, high humidity, salt spray, oil contamination, dust and sewage, severe vibration, and even collisions. Therefore, conductive slip rings for construction machinery have special requirements for waterproof, dustproof, and impact-resistant protection levels, as well as vibration resistance, high and low temperature resistance, and corrosion resistance.
JINPAT engineering machinery conductive slip rings not only possess extremely high consistency and stability, but also undergo rigorous simulation testing for various application environments. These tests include high and low temperature high humidity cyclic impact testing, multi-angle long-term high-intensity vibration testing, brush pull-out force testing, temperature cycling high-voltage breakdown testing, and brush conduction resistance testing at high and low temperatures. This ensures the slip rings can operate safely and normally even in harsh outdoor environments.
