Introduction of Sany STC700T lifting capacity
1) Five-section large-section U-shaped main boom, the main boom is fully extended by 49.5 meters, and the secondary boom is 17.5 meters long;
2) The 7.7-meter lateral outrigger span, full counterweight 20t, main boom operating range up to 42m, lifting performance is more than 10% ahead of peers.
2. Super chassis performance
Super chassis performance:
1) The new 2.8-meter wide chassis, low front H-shaped movable legs + high-strength rectangular cross-section frame bring comprehensively improved torsion and bending resistance and ease of operation.
2) Weichai 350-horsepower torque-increasing engine, 10-speed gearbox with synchronizer, heavy-duty axle, maximum gradient of 45%, and fuel consumption per 100 kilometers of 42L.
3) The front axle is equipped with a new large-size disc brake, the braking torque is increased by 25%, the heat is less, and it is more reliable.
4) Equipped with 400L large-volume fuel tank, the endurance is increased by 15%.
3. Efficient and energy-saving hydraulic system
Efficient and energy-saving hydraulic system:
1) Newly developed dual-pump intelligent flow distribution system, with independent amplitude change, combined arm extension, and maneuverability of compound action increased by more than 50%.
2) Imported double-connected plunger pump, imported winch motor configuration to meet the requirements of precision lifting; the minimum stable speed of rotation is 0.15 ° / s, and the minimum stable speed of winding is 1.5m / min.
3) Compared with the hydraulic control system, the electric control system has a comprehensive energy saving of 15% and a 30% increase in heavy-duty operation efficiency.
4. Humanized manipulation
