FIELD: construction.
SUBSTANCE: invention is related to the field of construction, in particular to designs of crane rail track foundations, mainly to designs of crossing crane rail track foundations. Beam comprises longitudinal part with foundation expanded down and support platform on top for rail installation on it, at the same time elements of fixation to beam of crane rail track are located in platform contour. Beam is arranged with transverse parts, which protrude from longitudinal part to opposite sides, at the same time transverse parts have foundations expanded down and upper support platforms, arranged aflush with support platform of longitudinal part of beam. In contour of upper support platforms of beam transverse parts there are elements located for fixation of transverse rail of crane rail track. Length of longitudinal part of beam is more than length of its transverse part, and length of transverse parts to centre of their crossing with longitudinal part are equal.
EFFECT: provision of possibility for reliable installation on beam of longitudinal and crossing transverse rail tracks on foundations of crossing rail tracks to change direction of tower crane movement from longitudinal to transverse direction of motion.
