Displacement compensators for the skylines of timber transportation cableways

Cableways for timber transportation are quite effective in terms of manufacturability, specific energy consumption, material capacity and the negative impact level on environment difficult natural operating conditions, compared to similar types machines. Since non-stationary cableways usually used forestry production, which characterized by a light construction with relatively small safety margins cable equipment elements, then this type roads, reliability skylines work important factors their operation. In order reduce cost duration installation dismantling operations, rigidly fixed trees, stumps or artificial supports. Such fastening scheme is technically convenient, but it does not allow constant tension when carriage load moving along span, under wind load, possible temperature fluctuations, icing structural emergency situations. As result, intensive changes during operation cause dynamic loads vibrations rigging, as well uneven accelerated wear skylines, decrease durability. Under such increase rigging (both individual existing models latest ones), proposed equip them displacement compensators skylines. After analyzing number prototype devices that effectively related industries, was concluded pneumatic, mechanical, hydraulic compensator designs can be considered rational production. Therefore, view above, we performed detailed calculation designed main technical elements compensating device, developed control its working body, analyzed stress-strain state using Autodesk Inventor software package. The use appropriate schemes bodies will create prerequisites reliable safe various modes terrain climatic minimize likelihood emergencies
