The ConsuLab HV-125-BWP is everything you’ve always dreamed about when teaching air brakes systems. Imagine being able to take the entire class out for a road test and watch live data on a scan tool and see what happens when you drive on dry pavement, during full throttle acceleration and a panic stop. Simulate a drive on an icy road and start to lose control, and you will get to demonstrate how the ABS and ESP functions. Students get to hear, feel and see how all the electronic control valves react during these ABS ESP and ATC events. You can demonstrate trailer sway, you can demonstrate traction control events. The trainer is built to be used as a live driving simulator in front of a whole class as well as for learning the foundation air brake system, performing electrical and pneumatic diagnosis with the aid of fault boxes, with optional defective components. The trainer has been designed around the FMVSS121 standard and allows students perform their pre-trip inspections. All components are D.O.T. approved. Optional foundation brake wheel ends with a drum front axle, spring brake disc and spring brake drum configuration give full coverage of how the mechanical foundation section of the brake’s functions. Students can see the S-cams move, you can watch the slack adjusters adjust, you can over or under adjust the brakes and see the results on the foundation disc and drum cutaways.
