Abstract

The proposed technique makes it possible to determine the parameters of the cross-section of the towers of artificial supports of cable yarders, depending on the selected profile of its structure. The initial data for the calculation are the height of the support and the maximum forces in the skyline and main line. The result of the calculation by the method is the outer diameter when choosing an annular section, the side of a square when choosing a square section. The basis of the method for determining the parameters is the loaded state of the tower during the execution of the main technological operation of the cycle – carriage in. The developed methodology is suitable for calculating installations with a rigid attachment of the tower to the winch body for the most common design of mobile cable yarding systems with a fixed carrying rope and an all-metal tower. The calculation of the section parameters is carried out with a static loading of the tower when performing a working stroke. The essence of the first technique is to determine the parameters of the section by the strength condition under the combined action of bending and compression from the forces in the traction and load-bearing ropes. The theoretical basis of the technique can be used in software calculations in such packages as MathCad.
