Portal Type Scraper Reclaimers
This portal reclaimer for an indoor installation features two reclaimer
booms with a pair of traversing scraper chains and scraper flights.
This arrangement is used to avoid interference with the roof structure;
an outdoor installation (see photo below) would use a single reclaimer
boom. To reclaim the stacked material, the reclaimer booms are lowered
until the scraper flights engage in the material while the portal
reclaimer moves along the pile. The scraped material is loaded onto a
yard conveyor alongside the pile.
The reclaimed capacity is controlled by varying the travel speed of the
machine.
