Alexandrovsk Machine-Building Plant is one of the oldest plants in Ural starting its history since 1802. 
Expansion Anchor Support is designed for support of excavations drifted in 2-4 Protodyakonov hardness laminated salt rocks; in such case the supporting strength of the anchor can reach 50 kN (5 tons). The diameter of the hole for the anchor support shall be within 41-43 mm.
