DEVELOPMENT OF A SPRING TENSIONING DEVICE OF THE SPEED LIMITER ROPE FOR ELEVATORS WITH A REDUCED SHAFT PIT
The article demonstrates the relevance of reducing the depth of the elevator shaft pit and focuses on the previously formulated concept of the minimum vertical dimension of the tensioning device based on its functional purpose. The dependence of the vertical dimension of a spring tensioning device on the elastic properties of the traction element and its diameter is shown. The design of the spring tensioning device with the minimum vertical dimension and with the function of partial compensation for the elastic rope elongation is proposed. The scope of application of the tensioner proposed is determined depending on the building height. Solutions are suggested for using universal devices to expand the area of applicability of the tensioning device under consideration.
