Product Description
Engineered with a 191 kW Weichai turbocharged diesel engine and a four-section boom extending to 47 meters, this 2021 Sany STC250T delivers 25-ton lifting capacity through a proven hydraulic system designed for precision load control. The proportional valve technology ensures smooth operation across the full working range, while the single-cylinder telescoping mechanism reduces hydraulic oil consumption by 18% compared to legacy designs.
Sany's STC-T series represents third-generation truck crane architecture, incorporating computerized moment limiting, automatic leveling protocols, and dual-pump load-sensing hydraulics that optimize fuel efficiency under variable load conditions. The reinforced H-beam outriggers provide a 6.8-meter maximum span, establishing stable working geometry on uneven terrain.
