WHAT IS IT? The Model VA is the newest belt alignment control specifically designed for use with bucket elevators. The unit is typically used in pairs to provide protection to both sides of the elevator leg, and indicates when the vertical belt strays or drifts beyond acceptable limits. After such time, the unit will trip an output to indicate a problem, or can be used to shut down the leg until inspection and correction is provided.
WHY IS IT NECESSARY? The Model VA is one of the most economical and reliable methods for meeting the OSHA requirements under the Code of Federal regulations 1910.272 for Grain Handling Facility Standards.
