The invention relates to a hoisting drive comprising several linear motors,
as well as to a linear slide track with a carriage. All primary parts and
all secondary parts of the linear motors are mounted on the carriage. The
hoisting drive comprises a closed housing which is cooled by a coolant and
into which the linear slide track is integrated together with the linear
motors. Those primary parts and secondary parts which are not mounted on
the carriage are mounted on the housing. A cylindrical hoisting rod is
introduced into the housing in a sealed manner and mechanically joined to
the carriage. This hoisting drive is especially suitable for use in the
iron and steel industry as replacement for large cylinders.
