摘要： PROBLEM TO BE SOLVED: To provide a maintenance work device for dumbwaiter capable of securing safety at the time of a maintenance work and rich in versatility. SOLUTION: This device is provided with a landing door switch having a contact opening and closing according to an opening/closing operation of a landing door, a maintenance time stop switch 3 which has a contact openable and closable by an operation part 3A and is serially connected with the contact of the landing door switch and a closing body 4 to be attached and detached to/from a position covering the operation part 3A of the maintenance time stop switch 3. When both of the contact of the landing door switch and the contact of the maintenance time stop switch 3 are closed, a car is made travelable. Because the operation part 3A can be made in an unoperable state if the closing body 4 is mounted so as top cover the operation part 3A making the contact of the maintenance time stop switch 3 into an opened state, the car is kept in a traveling stop state, even if the contact of the landing door switch is closed, and thereby an anxiety that the car starts to move is eliminated, even if call registrations are generated on other floors.
