THAYER SCALE-Hyer Industries “Quarry King” Conveyor Belt Scale Designed for Rugged, Maintenance-Free Operation


August 24, 2010

PEMBROKE, MA — Thayer Scale’s single idler “Quarry King” Conveyor Belt Scale has been specifically designed for outdoor conveyor weighing of dusty fines and “stone like” aggregate materials where rugged construction and spill-proof/jam-proof suspension design are the most essential attribute. Teaming with Thayer Scale’s proven “Rocking Flexure” fulcrums is a completely new “pipestem” single idler suspension system incorporating built–in storage means for its calibration weight (no test chains required).

This combination of unique elements provides important advantages for neglected-maintenance operations where on-going dust build-up and spilled aggregates are known to foul conventional suspension designs.  Applications include troughed belt conveyors of 18-48” widths operating at speeds up to 600 fpm and inclines up to 18 degrees.
