The apparatus has first engagement means to engage an upper part of the truck, second engagement means to engage the bolster and hydraulically actuated means connected at one end to the first engagement means and at the other end to the second engagement means to urge same together when actuated, whereby the bolster is raised to permit removal and replacement of the springs. Preferably, the first engagement means comprises a pair of hanger bars having hooks at their upper ends to engage the top of the truck and the second engagement means comprises a member slidably mounted on said hanger bars and having a portion insertable into the end of the bolster. The hydraulically actuated means preferably comprises a pair of piston and cylinder arrangements mounted one on each of the hanger bars at its lower end and engaging the slidably mounted member at its upper end.
