XCMG 803811840 Truck-Mounted Crane 20-Channel Slip Ring Brush Assembly
● XCMG 803811840 Brush Technical Support
● Part number 803811840 (model XGSC-200-20, supplier code 111278) is the genuine 20-channel conductive slip ring electric brush block assembly engineered for XCMG truck-mounted cranes.
● Material number 803811840 installs inside the center rotating swivel joint housing. Utilizing 20 spring-loaded high-conductivity copper-graphite brush blocks contacting rotating copper rings, it provides tangle-free, continuous 360-degree transmission of 24V power, solenoid valve outputs, remote control signals, and safety sensor data between chassis and upper boom superstructure.
● Periodically inspect carbon brush contact surface wear, check spring tension uniformity across all 20 channels, and keep the slip ring chamber dry and free of conductive dust.
