West River Conveyors offers hydraulic powered belt storage units and those that can be used in conjunction with constant tension winches. Belt storage units are available in any belt width and allow for multiple belt storage capacities from 40-50 feet up to 400-800 feet and larger. Multiple designs can be used for long panel advancements on a main belt line, preventing frequent belt splicing. When used with a constant tension winch, belt storage units are able to control belt tension by using load cells, an instrument used to measure force. Sophisticated VFD starters will control the tension based on the load cell reading. By working closely with customers, West River engineers will design configurations customized to your specifications and preferences.
