Ancient crane, also known as ancient crane . When building city walls in ancient times, it could lift heavier building materials to high places on the walls in order to save labor. Therefore, it is an important apparatus in ancient construction projects. This model mainly uses the principle of deceleration gear system and movable and fixed pulley set to save labor.
In this model, we use the principle of reduction gear system and movable and fixed pulley set to save energy. The crane is equipped with 8 wheels, which increases the mobility of the crane. Secondly, we added a turntable to adjust the swinging direction of the boom, which enlarges the working range of the crane.
Furthermore, two foldable stairs are added to the front of the body, which is convenient and simulates the real use scenario.
In addition, we added an ingenious device in the pulley block, which can effectively prevent the rope from falling off. The designers thought about this structure for almost a week! Based on the coordination of the pulley block, we provide three pulley block combinations. Friends can choose one of them according to their personal preferences to assemble and deepen their knowledge of the pulley block during play.
