A carriage comprising two sheaves 30, 40 which rotate around an axis between front and rear plates 10, 12. The carriage has an open configuration in which one sheave is spaced from the front or rear plate. The carriage may move into the open position by rotating the front and rear plates about an axis perpendicular to the plates. The axis of rotation of the plates may be coincident with the axis of rotation of one of the sheaves. There may be three or more sheaves. A locating means may be provided to releasably connect a sheave with the front or rear plate to prevent mutual rotation of the plates. The locating means may be a pin extending axially through the sheave and connected to the plate by a threaded connection. The carriage may have a recess forming a void, and a void plate to fill the void (20, fig 12).
