ABSTRACT The spring compressor for large helical springs, more especially motor-vehicle axle springs, consists of two loose plate-like pressure plates (1, 2) with helically coiled ring surfaces (33, 34) as supports for the spring coils and each with a central through hole (21, 24) and of a threaded spindle (4) and a threaded tube (3). The threaded spindle (4) is concentrically and rotatably mounted by means of a thrust bearing in a guide tube (5) which, in the vicinity of the spindle head provided with a spanner profile (9), comprises a radially outwardly projecting bearing surface (12) with two elements securing against rotation (13, 14) for the pressure plate (2) at the spindle head end. The threaded tube (3), which is provided at its end with a nut thread which can be screwed on the threaded spindle (4), can be telescopically inserted into this guide tube (5). The threaded tube (3) and the guide tube (5) are connected together so as to be secured against rotation by two slot/key joints (17/15 and 18/16). The threaded tube (3) is connectable to the other pressure plate so as to be secured against rotation and in the axial direction of tension by two radial fingers (19, 20) at the end of the threaded tube so that the two pressure plates (1 and 2) cannot be rotated relative to each other when a compression spring is compressed.
