The OvoJack Standard Series is a patented mechanical lifting jack engineered for safe, controlled lifting during maintenance, inspection, and temporary support of industrial structures. Built for reliability and simplicity, the Uni-Jack provides stable lifting without hydraulics.

The Uni-Jack uses a mechanical screw-jack system housed in a robust steel frame, delivering predictable lifting performance and high load stability. Designed for maintenance crews, shutdown teams, and fabrication yards, it eliminates hydraulic failure risks and provides safe, repeatable lifts for structural and equipment support.
