needed when parts weigh over 50 pounds (23 kg) for a single person lift, over 100
pounds (45 kg) for a two person lift, and over 150 pounds (68 kg) for a three or
more person lift. Do not try to handle heavy parts without lifting equipment. Keep

precaution could cause serious injury or death of personnel.
