Source Data

 Single-span workshop, 24m span

Equipped with two bridge cranes with a lifting capacity of 160/32t of heavy operating mode

Spacing of cross frames of frame 6m

Elevation of crane rail head 12800 mm

The length of the building is 96m

The vertical dimensions of the building depend on the process conditions of production and are determined by distances from the floor level to the head of the crane rail H1 and from the head of the crane rail to the bottom of the bearing structures of the coating H2. In total, these dimensions constitute the useful height of workshop H0.
