You could create a curve (1), a mechanic piece (2) and a subdivided plane (3) that has a Curve modifier with the curve as Curve Object:

enter image description here

Parent the piece to the plane, select the plane and in the Object panel > Instancing, click on Faces so that the piece is instanced on each face of the plane. Also, in the same panel, disable its visibility:

enter image description here

Move the plane on the correct axis (here on X):

enter image description here

As the object is actually made of 2 pieces, duplicate your plane, offset it a bit, create your second piece and parent it to this second plane:
