Abstract
An elevator speed measurement system includes a reflective sensing device that is supported within the hoistway. In one example, the reflective sensing device is a radar-type device that is supported for movement with the cab through the hoistway. Reflected signals off of a structural component within the hoistway provides information regarding speed of movement of the cab in the hoistway. The speed signals are then transmitted to a remotely located receiver that provides an indication to a technician of the speed of the elevator movement.
