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