An elevator for raising and lowering a hospital stretcher or the like without binding. The stabilized elevator has a pair of intermeshed timing gears at each end of the elevator which are connected by horizontal axles that are rotationally secured to a first telescoping section of the elevator. Each timing gear intermeshes with a vertical toothed rack secured to a second telescoping section adjacent each gear. The intermeshing timing gears and racks cooperate to keep the telescoping elevator from binding, particularly when the stretcher or the like has a heavier load at one end than the other.
