Above: NAMC’s Ed Barnett and Hubie Perez, along with WRQ’s Ronnie VanLandinham, lead a tour of White Rock’s enormous dragline. To get an idea of the machine’s size, notice the workers visible in the background at the base of the machine, just over the shoulder of the middle tour guide.

Below: Students and their teachers stand in the dragline’s huge bucket, which can lift up to 105 cu. yds. of limestone (weighing about 150 tons or 300,000 lbs.) per scoop. Thick cables and chains are used to hoist the bucket from the mining pit. During mining, water from Florida’s high water table streams out through the holes, while the “shot rock” remains inside the bucket. The material is dumped in stockpiles to dry, then transported to onsite production facilities where various sizes of aggregates and screenings are produced for use as construction materials.
