METHOD FOR LIFTING DEVICE MOTION PARAMETERS CONTROLLING Russian patent published in 2017 - IPC B66B5/00 

FIELD: transportation.

SUBSTANCE: invention relates to the test and measurement equipment, in particular, for operational monitoring of the mounting quality and driving parameters of the lifting device movable part, for example the lift, and may be used in the lifting devices of various purposes, where the winch mechanism is used, for example in buildings lifts, mines, escalators, moving walkways, conveyors, hoisting cranes. Proposed to perform the control by measuring deformation (stress) of the lifting device winch frame, by value of which judges on the parameters of lifting device movement. In particular, the deformation measurement is produced by the fixed deformation sensor on the winch frame, connected to the signal processing unit, which converts the incoming signals supplied during the operation from the deformation sensor into the information signals, representing the movement parameters of the lifting device movable part. The strain gauge piezoelectric transducer serves as the sensor. The sensor is placed on the winch frame preferably in the place of maximum deformations.

EFFECT: improved accuracy of measurements.
