Tri-Township Ambulance Service is all power:

As always, TTAS has made yet another advancement for patient care and comfort. TTEMS now has all power stretchers in every ambulance in the fleet. Not only are they all powered but six (6) have an expandable patient surface what we call "wings." The wing attachments on both sides of the stretcher allow for extra space and movement for the patient. All of our power stretchers are driven by a hydraulic system with a maximum load of 700 pounds.
