A telescopic pole for wind energy production with low environmental impact and its lifting system for a 60–250 kW turbine and a height of 30 m have been designed and manufactured. The tower, was raised and lowered by automation or by remote control, that allows one to differentiate the presence of the generator within the landscape over time. The jacking systems acting on the legs had a combination of holes (on the legs) and pegs actuated by hydraulic pistons. The aim of the paper was the experimental and the analytical verification of the stability condition of the steel piston as a lifting system of the prototype. An experimental investigation was carried out on small-scale specimens to examine the influence of lateral restraints constituted by external steel tubes and transverse devices to increase the buckling load and to ensure a stability condition during the elevation operation of the telescopic steel pole. Finally, the experimental results were numerically validated. The original contribution of the paper to research was the design of lifting system of telescopic wind tower though a steel piston with transverse stiffeners.

设计和制造了一种用于风能生产的伸缩杆，其对环境的影响很小，其升降系统适用于60–250 kW的涡轮机，高度为30 m。该塔是通过自动化或远程控制来升高和降低的，这使人们可以随着时间的推移区分发电机在景观中的存在。作用在腿上的顶升系统具有孔（在腿上）和由液压活塞致动的销子的组合。本文的目的是对作为原型提升系统的钢制活塞的稳定性条件进行实验和分析验证。对小型试样进行了实验研究，以检查由外部钢管和横向装置构成的侧向约束对增加伸缩屈曲载荷并确保伸缩钢杆抬高过程中的稳定性条件的影响。最后，对实验结果进行了数值验证。该论文对研究的最初贡献是通过带有横向加劲肋的钢制活塞设计的伸缩风塔举升系统。
