The 100-year-old Liberty Derrick moves a 4-ton block of granite at Waite Park’s summer festival.

Quarry Park and Nature Preserve presented a demonstration of its 100-year-old Liberty Derrick at the summer festival in Waite Park, Minnesota, on Saturday.

The derrick, which is similar to those used at granite quarries in the early- to mid-1900s, hoisted a 4-ton block of granite for the demonstration.

According to WJON, the Stearns County Parks Department acquired the derrick in 1996 and fully restored it in 2008. It remains on display at Quarry Park year-round, and the park puts the Liberty Derrick in operation once each year.
