Hydraulic Giants were used in placer mines to direct a high pressure jet of water towards a hillside to wash away gold trapped inside the gravel. They were also popular in construction projects that required the displacement of a large quantity of dirt, including the Panama Canal. The Joshua Hendy Iron Works of California manufactured Giants (also called Monitors) practically from their invention in the early 1850s until around the time of World War 2. This is based off a larger Hydraulic Giant that still survives at Malakoff Diggings State Park in North Bloomfield, California. This kit prints in 2 separate pieces, allowing the nozzle to pivot horizontally. A wooden base, wood counterweight box and additional pipes are not included.

Made-to-Order Manufacturing

At 3DPT, every model is manufactured to order rather than pulled from warehouse inventory. This approach allows us to offer an extensive catalog while ensuring each piece is produced with the care and attention it deserves.

Most orders ship within 7-14 business days. However, larger models, complex projects, and high-volume orders may require 4-6 weeks or longer due to extended print times and production requirements.

While extended lead times are uncommon, they may occasionally occur during periods of high demand or due to circumstances outside our control. We appreciate your understanding as we continue our mission of preserving transportation history in miniature through high-quality, made-to-order models.
