An overhead trolley conveyor is configured as a continuous closed loop. The delivery loop has a length of 120 m and the return loop = 80 m. All parts loaded at the load station are unloaded at the unload station. Each hook on the conveyor can hold one part and the hooks are separated by 4 m. Conveyor speed = 1.25 m/s. Determine
(a) Maximum number of parts in the conveyor system,
(b) Parts flow rate; and
(c) Maximum loading and unloading times that are compatible with the operation of the conveyor system?
