Two basic styles of stacker reclaimers utilizing three different configurations of trailing tripper structures typically meet most storage requirements for bulk ports, terminals, electric power stations and other facilities where efficient stockpile management of raw materials is essential. Trench-type stacker reclaimer is ideal for installations with low-volume, high-active storage pile capacities between 30, 000 and 60, 000 tons, where reclaiming operations are accomplished by a longitudinal pass through the pile. Reclaim rates usually vary from 2, 000 to 4, 500 tons. Slewing-type stacker reclaimers are typically used where large quantities of material must be readily available, where blending of grades of material is required or where available yard length is limited.
