Removal of material from bulk storage

摘要

A gantry-less scraper device with a pivoted jib for the removal of material from a bulk storage dump having a dump delimiting wall at the machine side. The device travels along the machine side of the dump on a first rail spaced from the base of the delimiting wall and on a second rail on the side of the delimiting wall near its top. The device does not require a rail on the far side of the dump, does not require support from a shed over the dump, and does not require clearance for a counterweight.
