The speed of ascent and descent shall be within 30 cm per minute, and the upper limit of height shall be 70 cm from the bottom of e to the upper surface of d. FIG. 3 is a side view when it is most lowered. The forward inclination angle of d is opposite to that when it rises, gradually decreases and becomes smaller, and when it descends most, the base of d becomes almost horizontal.
