Kabinopus, the cart was designed with special curb and stair skids, which would easily handle curbs to 8 inches high. Having never visited Russia, I don' know how high the curbs, but most of those in this part of the world are just 6 inches high, as mandated by local laws.

Good luck on whatever you decide upon,
