FIELD: cranes. SUBSTANCE: the crane-reloader supports are fixed in the design position with the aid of metalworks of auxiliary supports of the trestle work, on which the bridge is assembled. The fixture is furnished with tackle- blocks with cross-pieces and mounting winches engageable with the tackle-blocks for hoisting the bridge of the crane-reloader from the auxiliary trestle work to the design position to the design supports. EFFECT: reduced time of mounting, reduced labour content, enhanced technical culture of work owing to exclusion of manual labour in linking and reeving of guy tackle-blocks and wind braces, enhanced reliability. 2 dwg
