Do you remember that the GBC 37 Ratchet Ride drives the conveyor belt in a vary unique manner?
As the LEGO 42097 Compact Crawler Crane set does not include any sprockets to drive it we had to come up with a new mechanism to use the conveyor belt.
A cleverly designed ratchet mechanism clicks into place and takes the belt up on every stroke upwards. This makes for the go-stop motion as you can see in the fan build below from Garin Taylor from Australia. Thanks for sharing the video with us.
