Control handle for power operated hoist, contains cavity with sensor for measuring pressure deviation when vertical force is applied to handle

摘要

A pressure sensor is used to measure pressure deviations from atmospheric pressure and is connected to a cavity in the handle comprising a flexible membrane connected to the grip part of the handle so that when a vertical force is exerted on the handle, a pressure deviation is created inside the cavity. This deviation, which is proportional to the vertical force, is recorded by a control unit for regulating the drive device for the hoist.
