رافعة ساني 50 مستعملة

The advantages of Sany’s 50-ton crane mainly include the following aspects:

Excellent performance: Sany’s 50-ton crane (such as the STC500C5-8 series) uses a 5-section boom and a U-section high-strength structural steel boom, with the main boom fully extended to 45.5 meters. The total length of the main boom and auxiliary boom can reach 61.5 meters, the maximum lifting height is 62 meters, and the maximum lifting torque reaches 1995kN.m (10.5t counterweight). In addition, this model has a G-class chassis, good passing performance, dual-axle drive, a maximum driving speed of 90km/h, and a maximum climbing grade of 47%.
High efficiency and energy saving: The crane adopts a fully electronic control system and a high-pressure double-coupled plunger pump, which is durable and efficient. Dynamic compensation technology can realize compound action flow compensation, telescopic buffering, making the operation more precise and smoother. Compared with the hydraulic control system, the electronic control system can save 15% of the overall energy for loading and unloading, and improve the efficiency of heavy-load operation by 30%.
