For a better understanding of hydraulics and construction machines, look no further than Pitsco’s Backhoe. The Backhoe uses hydraulic syringes to move the axes. Four controls are constructed from the syringes to imitate the basic controls of a real-life backhoe. A single student can operate all the controls, or a group of four can operate the controls as a team. With the shovel on the end of the Backhoe, students can get a feel for how large construction machines work!
