• supported or sustained by rack and pinion, rope traction drive, noncircular elastomeric-coated suspension means (hereafter called traction belts) traction drive, rope positive drive, chains, timing belts, screw and nut, guided chain or hydraulic jack (direct or indirect);

• with enclosed wells;

• with a rated speed not greater than 0,15 m/s;

• with the carrier completely enclosed;

• with a temperature in the well and in the machinery spaces between +5 °C and +40 °C.
