Four stations Carousel for the assembly of the bicycle. It is composed by four groups “Expans” (see description on the same catalogue) which are assembled, one in front the other, on four supports, and permit the assembly of the bicycles. The assembly, can be done as an assembly line, (by different operators, each one assembles different accessories), or with complete single bicycle for each operator. To get free the assembly position is necessary to push a pneumatic pedal and the positioning of the bicycle in another station is done by manual pushing.
