A pulley assembly and an installation for moving objects incorporating such a pulley assembly are disclosed. The pulley comprises first and second plates (10, 12) disposed about a median plane (M). One or more sheaves (20) are disposed between the plates (10, 12). The or each sheave (20) is carried for rotation about a respective sheave axis that is perpendicular to the median plane (M). A bollard (50) extends between the plates to provides an interconnection between the plates. The bollard (50) is shaped, whereby its dimension in a direction along a major dimension line (A), which dimension line that extends radially from one of the sheave axes, is greater than its dimension in a direction perpendicular (B) to that dimension line.
