[0002] Tower cranes (hereinafter referred to as tower cranes) are a kind of vertical material transportation machinery, which are widely used in construction, water conservancy, ports and other construction operations. The hoisting operation of tower cranes mainly relies on manual operation at high altitudes. This operation mode generally has problems such as poor working environment, high risk of high-altitude operation, narrow working environment, and obstructed working vision. Once the main structure of the tower crane is deformed or overturned, the tower crane driver is often unable to escape and is in danger. With the rapid development of the country's social economy today, people's requirements for living environment conditions have increased, and the rapid increase in the construction volume of high-rise buildings has led to a sharp increase in the use of tower cranes and their driving operators. The increase in personnel, the huge workforce of enterprises, high costs, low efficiency and difficulty in management have increased construction risks and costs, and the benefits have declined. In addition, due to the high floors of existing buildings, tower cranes are even higher. It is dangerous and difficult for drivers to climb when going to and from get off work. Climbing up and down when lifting temporary sporadic materials is not only time-consuming and laborious, but also inconvenient and unsafe, and the work efficiency during the period is extremely low.
