ABSTRACT:
A pulley for assisting in the deployment or take-up of a heterogeneous system including modules configured to be placed or being placed in an environment. These modules are connected via connecting members and the pulley is configured to be mounted rotatably on a shaft placed above the environment. The pulley includes first cooperating members configured to cooperate with the connecting members and second cooperating members configured to cooperate with the modules. The first and second cooperating members are configured to produce two successive operating states, namely, a first state during which the pulley is substantially stationary in rotation around the shaft and a second state corresponding to the passage of the modules, during which the pulley is driven in rotation around the shaft.
