dumb waiter (vertical lift)


Recommended Posts



I am at present working on a dumb waiter (vertical lift). The problem that I have is that I do not have any electrical drawings for the control side. This dumb waiter is about 50 yrs old (1950`s) single phase reversing motor (240v).


The motor, gear box and brake have over hauled and re fitted, but I can not connect the motor up as I do not know the wiring configuration, to the control side.


What I require is electrical drawings for the dumb waiter, for a 3-floor system with interlocks and floor selection, and also drawing of how the motor is connected up.


Please note any assistance is grateful
