Closed loop control principle: Optional single, double or multiple columns
operation, PLC real time control for high accuracy ;
Human engineering: each column is equipped with control system,
applies to six, eight or more columns; This set is composed of 1 master
column and 3 slave columns; each column is equipped with hydraulic
power unit.;
Safety precautions: mechanical and hydraulic double locking H function
when loading, overload protection; up/down limit switc
Failure self diagnosis function: when seriously asynchronous or column
power failure, the lift stops immediately.
