Abstract

PROBLEM TO BE SOLVED: To provide a lift device which ensures the safety of bathers and operators and is easy to handle by having a control part for controlling lift operation and an announcing part which announces the operating condition of the control part using voiced language. SOLUTION: A bathing person in a bathing position is put on the seat of a truck, the truck is connected to a lift, and the seat is put on a mount via an expansion rail. Then a control part 5 is operated to lower the person into hot water in a bathtub for bathing. Then the lift is directed to rise or fall by means of the rise and fall switches 35, 36 of the control part 5. A language generating part 34 generates language in synchronization with the action of the lift, and displays letters with voice on an announcing part 26; i.e., the seat is put on the mount, and a lock detector 42 detects that the seat is locked on the mount. A detection signal of the lock detector 4 causes generation of the language 'locked.' and displaying of letters. For every action, announcements are similarly made.
