A specialized vehicle manufacturer recently completed the delivery of its first batch of 50 rear-loading compactor garbage trucks, specifically for the sanitation system of a western province. These vehicles are optimized for high-altitude and low-temperature environments, employing a cold-resistant hydraulic system and a high-powered engine to ensure normal operation even at temperatures as low as -25°C. Prior to delivery, all vehicles underwent a 500-kilometer reliability test and compression performance test, achieving a 100% pass rate. The local sanitation department stated that the new trucks will replace older open-top garbage trucks, reducing garbage spillage and odor problems during transportation and improving the quality of urban environmental sanitation.
