Control voltages only control the entire operation of the
crane or machine.operating voltage will be hire. if we use
low control voltage it is safe for the person who is
operating the equipment. For control pendent push buttons
only control voltage is supplied,if there is earth fault the
pendent operator will not get heavy shock. there are other
control voltage like 24,48 volts also used in machine tools
and other equipments. it is for only the safety condition of
the operator low voltage is used.
