Product Description

Screw Jack System-Tank Lifting Construction Equipment
Petroleum storage tank is an important storage facility in the petroleum industry, and its construction quality directly affects the safe operation and service life of the storage tank. In the installation and maintenance of petroleum storage tanks, jacking operations are particularly critical, requiring precise control and a high degree of safety.
With the continuous advancement of industrial technology, the demand for precise control of heavy equipment is also increasing. As a widely used and superior jacking solution, the design of the lead screw jacking machine not only requires strong bearing capacity and high stability, but also takes into account the convenience and safety of operation.

The purpose of this scheme is to illustrate the application and advantages of lead screw jacking in the construction of oil storage tanks.
