The Air-Lift quick-access system for circular vibratory screeners allows rapid interior cleaning, inspection and screen changes while reducing manual effort. The device consists of two vertically mounted air cylinders that are located on opposing sides of any circular screener and affixed to mounting brackets on the lower and upper screening frames.
To operate, a quick-acting band clamp connecting the frames is removed and a remote air valve is actuated, raising the upper frame(s). The procedure is reversed to reconnect the frames. One entire raise/lower cycle, including disconnection and reconnection of the frames, can reportedly be accomplished in five minutes, reducing downtime during inspection, cleaning and screen-changes. In addition, one operator can now perform what was previously a two-person task, depending on screen diameter.
