Sand Transporter
Built by John Gay in September 2006 for the Crane Building Kit Models Secretary’s Challenge
This model is based on a tin toy from the 1940s — 1950s.
Sand is poured into the hopper and fills the trolley which runs down to the bottom of the track and empties. Gravity returns the trolley to the top.
Pouring the sand must be done carefully as it any spills onto the track the trolley will stick.
