SANY builds powerful hoisting structures for the big crane SCC16000

SANY SCC16000 big crane is one of the SCC series crawler cranes, used for construction of buildings, wind power plants, nuclear power plants etc. It is equipped with 12-cyliner, water-cooled turbocharging engine, with the rated power of 746kW, the rated speed of 1800rpm, the maximum output torque of 4629N·m and the maximum output torque speed of 1300rpm.

The hydraulic system of the big crane includes lifting hydraulic system, traveling hydraulic system, rotary hydraulic system, luffing hydraulic system, servo hydraulic system, backstop hydraulic system, cooling system, and auxiliary hydraulic system etc. The closed circuits are employed for all main systems of the big crane, which is characterized by the energy saving, high efficiency, good controllability as well as smooth startup, stop and directional control, impact-free, fast operation response, less heat and long service life.

The variable hydraulic motor installed in the big crane can drive the planetary gear reducer to control the lifting and lowering of the boom and jib winches. The stepless speed regulation is available based on the user’s needs during operations, with the maximum speed within the range of 0-121 m / min. It is characterized by the excellent micro-speed performance; the fastest gear can achieve the fast power lifting operation; the maximum magnification is 52; high quality wire rope is used, ensuring the multi-layer winding of the drum is always in order.

Slewing part of the big crane is driven by four motor reducers, with the smooth slewing speed of 0 ~ 0.41r/min, and neutral position free sliding function, which can provide 360 ° rotation. Luffing Mechanism of the big crane consists of boom luffing device, jib luffing device, and superlift luffing device. Fold-line drum, embedded reducer, high quality wire rope and closed circuit are adopted in the luffing mechanism. And the power can be provided through the switching over of direction change valve; many complex actions can be achieved.
