     The  tank was put on the roller, While the tank rolling and rolling ,the tank maybe traverse. If we lift the roller, the tank may be move to the opposite direction. We ortern use hydraulic push / pull as the photos, this type is the simple and save money.

     Another thing, we want to connect 2 tank and get a good joint , so we must lift up one tank, may link to another tank, and then weld a spot .
