Heavy-Duty Intelligent Asphalt Distributor with Siemens PLC Control, Thermal Oil Heating & Touchscreen Operation. Built on a Dongfeng heavy-duty chassis with a 165HP Yuchai engine, double-layer frame, and 245/70R19.5 vacuum tires, providing strong power and superior load capacity. Intelligent control system with Siemens PLC and touchscreen interface enables precise application rate control, real-time parameter monitoring, and automatic/manual one-key switching. Thermal oil heating with dual-layer piping (bottom and middle of tank) ensures rapid temperature rise and excellent heat retention, and easily removes demulsified asphalt from the tank bottom. Hydraulic drive system ensures safe, reliable, and quiet operation; equipped with an oil cooler to prevent overheating during continuous summer operation. Inverter power supply provides stable voltage to the burner, significantly reducing failure rates and improving reliability. Each of the 29 nozzles is independently controllable; spraying width can be adjusted during operation without stopping. After operation completion, one-key automatic oil return and cleaning function saves time and labor.
