Adjustable extension links, type ПРР

Adjustable extension links are intended for stepwise adjustment of the suspension set length and installation of beam yoke plates, type 2КЛ, 3КЛ, 4КЛ, 5КЛ and others. Adjustable extension links, type ПРР consist of four plates which if combined in pairs form clevis and tongue sides of a link. Plates have eyes with a different pitch that allows variation of the length of a link and consequently of a suspension set by means of shifting the cotter-pins between the eyes. Plate on the tongue side has excesses allowing provision of the standard dimensions of the eyes. The link is completed with two threaded pins, nuts and dowels. Adjustable extension links, type ПРР meet the requirements of TU U 31.2-30255335-002:2006.
