FIELD: transport.
SUBSTANCE: invention relates to construction, in particular to designs of crossing tracks intended for tower crane motion. Proposed base comprises plates arranged on construction site ground to support lengthwise beams that make lengthwise track supports. It comprises also crosswise beams jointed together to make crosswise track supports. Lengthwise and crosswise beams cross each other at an angle. X-shaped beam is arranged at the crossing point of aforesaid beams, coupled therewith. There are supports for jacks to lift crane frame, arranged all along the contour formed by lengthwise and crosswise beams. Thickness of each support exceeds that of the plate. Note here that gaps are formed between the support and plates adjoining it.
EFFECT: expanded performances.
