Artifact History: *Most likely involved in Oahu's road construction as it also lies within the region of the Tar Boiler, the Holt Caterpillars, and reports of a vintage steam-era road paver (location unrecorded). However it is possible that it may also have been used to haul coal for the inter-island steamships.
Artifact Condition: The bed of this truck is decaying away in the middle. There are large pieces of dredge debris lying about on it. The truck is equipped with a hydraulic pulley hoist system for dumping it's load. Also present along it's side, back to the rear axel is the chain drive system. The vehicle cab is largely deteriorated. The spoked wheels were in use until 1924. There are twin sets of rear wheels. All wheels have hard rubber treads. There is a hinge on the rear bed for a dump gate.
Additional Information: The Mack AC was affectionately nick-named the Bulldog by British troops in WWI for it's strength and unique front end. The company adopted it in 1922, but it didn't ride the hoods of their vehicles until 1932 although has ever since. Over 40,000 Mack AC's were built up until 1932, however the dump truck model, especially the pulley-hoist type were few.
