English: The hoisting crane has a simple structure, consisting of a rotating shaft fixed to the base, which helps the crane stand firmly during the loading process. The rotary joint is equipped with a safety latch that helps to fix the crane after turning to the desired position. The lifting and moving large loads of goods throughout the day takes a lot of time, effort and potential risks, especially in high-rise buildings, heavy goods weighing tons. Electric winches and cranes help optimize the cost problem but also minimize the risks to workers.
