Abstract
A carriage comprises a frame having load-bearing and guide rollers to enable it to roll longitudinally of a tube bundle puller while supporting a tube bundle. On each of two sides of the frame the carriage has two links which are commonly pivoted at one end and at their other ends are provided with members engaged by an elongate bolt rotation of which causes the members to move towards or away from one another. The carriage permits tube bundles of various diameter to be supported directly or indirectly by the members at a proper height.
