In the power transmission and transformation system of the power grid, the high-voltage power of the power grid can only be powered by the capacitor device. Due to the development of new power transmission technologies, the voltage level of the power grid is getting higher and higher, so the height of the tower where the capacitor is installed is also getting higher and higher. Because the capacitors are densely arranged, the gaps between adjacent capacitors are very small, and it is very difficult to carry the weight of a single capacitor only by manpower. Therefore, mechanical equipment or mechanical devices are required for maintenance and hoisting, and general-purpose lifting equipment It is impossible to enter a narrow space for operations. Although the special lifting work platform for the maintenance of electric capacitor towers is convenient to use, high in efficiency and strong in applicability, it is expensive, so a simple capacitor hoisting device is needed.
