The suspension platform is composed of suspension device, platform, traction hoist, SafeLock, electric control system, wire rope, and other major components. The suspension device is fixed in the cylinder wall, and the platform relies on its own hoist along the steel wire rope to climb. Operators can run up and down in the vertical direction, and they can be free to hover at any height for work. The whole system is self-contained, flexible, and convenient to use without any external assistance. Modular main structure and aluminum alloy material of the standard section are spliced into the required diameter of the tower platform.
