Overview

With a service weight of up to 14,000 t, a length of more than 200 m and a transport capacity of 240,000 cubic metres per day, the excavators and spreaders used in German lignite mining are among the largest mobile machines in the world. The standard applies to the construction, commissioning and periodic testing of equipment for extraction and conveyance processes in opencase lignite mines. Equipment is excavators, spreaders and auxiliary equipment with an operating mass from 200 t, auxiliary equipment only in so far as they are moveable on their own running gear. Floating excavators are excluded from the scope. Particular requirements are applicable for large-scale equipment. Included are: a) bucket wheel excavators with a bucket volume of more than 800 l or a service weight of more than 1 000 t or a feed of the bucket-wheel jib of more than 15 m, b) bucket-chain excavators with a bucket volume of more than 800 l or a service weight of more than 1 000 t, c) spreaders with a service weight of more than 800 t or a boom length of more than 50 m as well as d) auxiliary equipment which correspond to the size or service weight of the previously listed equipment. Apart from editorial changes, the changes to the existing standard mainly relate to adaptation to the current construction standards (Eurocodes). The standard has been prepared by Working Committee NA 008-10-01 AA "Bagger, Absetzer und Zusatzgeräte in Braunkohlentagebauen" ("Excavators, spreaders and auxiliary equipment in opencase lignite mines") of FABERG.
