• Strong stability: SANY tower crane has a solid tower structure, stable chassis design, and a high-precision balancing system, which can maintain stable operation under complex working conditions and reduce safety risks.
• Easy operation: Equipped with a user-friendly operation interface and advanced control system, the operation is simple and easy to understand, enabling precise control of the lifting, luffing, and slewing of the hook, thus improving the accuracy of operations.
• Reliable brand: As a world-renowned construction machinery manufacturer, SANY ensures product quality and after-sales service. Used equipment can still maintain good performance under proper maintenance.

It is mainly used in various construction projects, such as the construction of high-rise residential buildings, commercial complexes, and industrial plants, responsible for lifting construction materials such as steel bars, concrete, and formwork, as well as installing prefabricated components. It is also applicable to infrastructure construction projects such as bridges and large venues.

(for common models, specific parameters may vary by model)

• Structural component wear: As a used equipment, structural components such as the tower body and jib may have a certain degree of wear, such as paint peeling and weld cracking, which require regular inspection and maintenance.
• Electrical system failure: After long-term use, electrical circuits may have problems such as aging and poor contact, leading to unstable operation or failure of the equipment. It is necessary to timely check and replace aging components.
• Lubrication system issues: If maintenance is not in place, the lubrication system may be blocked or lack oil, affecting the normal operation of various moving parts and increasing wear. It is necessary to regularly check and replenish lubricating oil.
• Failure of safety devices: Safety devices such as limiters and overload protectors may have reduced accuracy or failure due to long service life. They must be regularly debugged and calibrated to ensure reliable operation.
