Rail stressor, rail tensor KZDM-70

    Due to the sharp increase in the number of continuous welded rail network, all railways need powerful and reliable rail tensors with great force pulling.

    Kubanzheldormash produces railway stressors for track maintenance. KZDM-70 hydraulic rail tensor is designed to adjust the gap between rail ends for rail stressing, rail welding and for installing insulated joints. Also it’s used for repairing rail failures.
Professional KZDM-70 hydraulic rail stressor is efficient and modern solution with many design and technological innovations. Tensor fully self-contained, hand-blown operating pressure of hydraulic station which supplies the working fluid in the hydraulic tensioner rail.

    With the hydraulic rail stressor the continuous welded rail may be pulled for rail distressing operations during aluminothermic welding. Simple and solid design, robust steel elements, durable high-pressure hoses, precision metal hydraulic cylinders, all these factors make KZDM-70 rail hydraulic stressor one of the most popular in the market. If we take into account such criteria as quality / price ratio, rail tensor KZHDM-70 is the undisputed leader in the railway market.

Benefits of KZDM-70 hydraulic rail puller
