The purpose of this scheme is to illustrate the application and advantages of lead screw jacking in the construction of oil storage tanks.
The design goal of the lead screw jack is to achieve efficient, stable and safe jacking operations. The design takes into account the convenience of user operation, the reliability of the equipment and the ease of maintenance.
As an advanced mechanical tool, the lead screw jacking machine has been widely used in the construction of petroleum storage tanks because of its advantages of simple structure, convenient operation, strong bearing capacity and stable jacking.
