Retractable rolling mill instrumentation platform

摘要

A retractable instrumentation platform for supporting instrumentation adjacent a roll of a rolling mill. This platform is accurately positioned within a rolling mill at a preselected elevation and it is retractable away from the monitored roll, when desired, for maintenance or other purposes. The re-positioning of this platform within the rolling mill after being retracted is accurately controlled such that it is returned back to its original reference elevation without the need to re-calibrate the supported instrumentation.
