Device for controlling the traction exerted by pulling apparatuses: winches, capstan-winches and linear winches such as belt or roller conveyors

摘要

The apparatus is mounted on a subframe by means of parts leaving very little latitude of movement. This movement is blocked by one or more parts which are judiciously placed and calibrated. The forces taken up by the blocking parts are monitored by strain gauges. The values displayed by the strain gauges are used for activating measuring instruments, warning signals and/or for controlling the driving of the apparatus itself.
