DESCRIPTION
Two column lift equipped with two arm trolleys driven by trapezoidal screws.
The movement between one screw and the other is transmitted by means of a
chain.
A metal cable has three functions: descent limit switch and safety device in
case the main nut is completely worn or the chain breaks.
The motor is protected from overloads and in case of overheating it stops; it is
also protected against accidental start-up when the electricity returns after a
power failure.
