Why APPI: Servicing and changing heavy filter plates on a custom MCRO filter unit from Sparkler Filters is a challenging and time-consuming process, especially on a large-scale unit with multiple individual filter plates. In order to accomplish this task, Phil Lawson, purchasing agent for Sparkler Filters, turned to APPI to engineer filter hoists that could provide the necessary lift and travel to help perform the routine maintenance on this unit.
In operation, the Columbia Hammerhead Trolley is mounted on an I-Beam, called the “Bridge”, which is mounted perpendicularly to the filter frame. The bridge traverses the filter frame while the hammerhead trolley moves along the bridge in order to be positioned directly above each filter plate throughout the vessel. When the hoist is in position and connected, the filter plate is lifted out of the vessel for cleaning or replacement.
Once installed, Lawson said the Columbia pneumatic hoist and hammerhead trolley were clearly the right choice for this application as they have performed flawlessly since installation.
