Zusammenfassung:	FIELD: construction and operation of steel jib-type headframes; may be used in sinking, deepening and operation of mine vertical ventilating and auxiliary shafts, including those on loose grounds and mined territories. SUBSTANCE: device is made in the form of steel single-jib semitent headframe with nonbearing frame stand. Frame post is vertical and tubular in cross-section and main bearing framework has circular box-like or tubular strut on which sheave wheel platform or unloading sinking platform is located. EFFECT: excluded use of temporary sinking headframe, reduced terms of mounting and labor inputs, and decreased specific metal consumption. 4 dwgn
