Dumbwaiter

Dumbwaiters, also called dumbwaiter lifts, dumbwaiter elevators or food lifts, provide a fast, convenient and economical transportation method as a small freight elevator in different buildings, significantly saving time and labor. This sundries elevator is widely used in hotels, restaurants, residences, banks, office buildings, hospitals, commercial buildings, factories, libraries, cleaning rooms (reaching 0.3μ, class 1000), laboratories, and post offices to carry food, drinks, tableware, daily necessities, coins, documents, medicine, goods, books, letters and more.

Features of the Sundries Elevator
1. Diverse Control, Stable Operation
The dumbwaiter can be operated using PLC control, microcomputer control, serial communication control, and variable frequency control. The diverse control systems ensure a stable and safe operation.

2. High Safety and Reliability
An IR light curtain and photoelectric height limit further enhance the safety and reliability of the lift door.

3. Special Design
To match specific working environments, the sundries elevator comes with sealing functions, as well as a water and oil proof system that performs double protection.

4. Overtime Running Protection
When the electric lift runs for more than 10 seconds, in idle use, the main circuit of the motor will be cut off to stop the lift to prevent motor burnout.

5. Contactor Connection Protection
When the contactor fails to disconnect contact after a lack of power, the elevator can't implement the next running proves, which ensures absolute safety.

6. Remarkable Features
1) The lift door system comes with a modular design that makes the installation and change easier.
2) The pulley that allows the door to hang and the device that prevents the door from moving out of its slot both feature a unique design, preventing the elevator from falling off the door cable.
3) A wire rope cable on the door is completely hidden in the slide way to prevent damage during maintenance or system failures.
4) The door system of the sundries elevator will be assembled and debugged before delivery. This improves installation quality and speed.
