Dump Trucks, Crane and Backhoe

Three dump trucks, a railway crane and a backhoe all operate off the same servo controller device.  The dump trucks came with movable boxes but I had to modify the crane and backhoe to do what they do.

Each item has a small servo motor attached to it.  Programming was done with  Lynxmotion sequence software.

 

The models are shown on the bench in the video but all have been installed on the train layout in a "natural environment".
