FIELD: construction, particularly conveying or assembling building elements, namely devices to install roof beams and trusses in vertical position and for temporary unfastening.
SUBSTANCE: roof beam system assemblage device comprises conductor frame with guiding means fastened to column, hoisting mechanism and two electromechanical jacks. Building structure is installed in vertical position by means of executive tools of electromechanical jacks. Electromechanical jacks are activated by means of electric level gauge installed on upper end part of roof beam system and including one horizontal and two vertical electric contacts and mercury layer. As roof beam structure bends mercury layer completes circuit to bring electromechanical jack in operation.
EFFECT: decreased labor inputs for assemblage works performing.
