A support assembly for process control equipment includes a cabinet containing processing equipment. A vertical support pole is supported on said cabinet through a collar for extension and retraction. Process control equipment such as electronic control equipment and a video monitor is mounted on the upper end of the pole. At least one, and preferably two, constant force springs biased into a fully coiled position are attached at one end to the lower end of the pole. The opposite end of the springs are mounted for free rotation on a spool which is secured to the cabinet, whereby raising and lowering of the process control equipment is facilitated.
