In modern life, when faced with towering skyscrapers, we have become inseparable from our reliance on elevators. Living and working in skyscrapers that reach dozens of stories high, the absence of elevators seems as inconceivable as the satirical animations from the childhood of many young people. However, with the increasing number of floors in the use of elevators, the safety of elevator usage has become increasingly important. Among the safety features for elevator installations, the Elevator Balance Compensation Chain plays a very important role. The structure of the elevator balance compensation chain generally includes iron chains, rubber columns, and fiber layers, with the iron chains placed inside the rubber columns, and the rubber columns wrapped with fiber layers. Its characteristic lies in: it includes iron chains, rubber columns, and fiber layers, with the iron chains placed inside the rubber columns, and the rubber columns wrapped with fiber layers.
During the operation of the elevator, the lengths of the steel wires on the car side and the counterweight side will continuously change, causing the weight of the steel wires on both sides of the traction wheel to change accordingly. When the elevator car is at the lowest floor, most of the weight of the steel wires acts on the car side. When the car is at the highest floor, most of the weight of the steel wires acts on the counterweight side. Such changes have little impact on the performance during the ascent, but when the ascent exceeds a certain horizontal height, it begins to seriously affect the stability of the elevator's operation, affecting the safety of passengers. Therefore, when the height of the floors used by the elevator reaches a certain height, it is necessary to add an elevator balance compensation chain to the elevator system.
