Abstract
An apparatus for a decoking system, for raising and lowering a cutting tool into a coking drum, has at least one rigid vertical member extending above the coking drum with a toothed rack extending substantially the full height of the member. A rigid frame with provisions for mounting a cutting tool is movably mounted to the rigid vertical member. A motor is mounted to the rigid frame and powers a pinion gear which is drivably engaged on the toothed rack such that rotation of the pinion gear raises or lowers the rigid frame on the vertical member.
