How many years is the service life of a construction tower crane?

The service life of a tower crane is generally 10 years. If it is well maintained and passed the inspection by the inspection department, it can continue to be used.
Tower crane is the most commonly used lifting equipment on construction sites, also known as tower crane. It is connected section by section, referred to as standard section, and is used to lift construction materials such as steel bars, wooden slats, concrete, and steel pipes. The function of the tower crane tip is to bear the upper load transmitted by the arm rope and the balance arm rope, and directly transmit it to the tower structure through the turntable through the structural components such as the rotating tower, turntable, and bearing. The self-lifting tower top has truncated cone column type, forward or backward truncated cone column type, herringbone type, and diagonal support frame type.
