Demonstrating power in bearing repairs in narrow spaces! A small jack can achieve a large lifting force.
The "Tri-Up System" breaks the conventional concept of pushing hydraulic jacks upward and instead raises them by pushing them sideways, representing a groundbreaking method for bearing repair. It transforms the traditionally large-scale girder reinforcement, temporary facilities, and equipment into a compact, lightweight, safe, and easy-to-use lifting temporary support system. With numerous achievements in bearing maintenance and repair across the country, it has received significant recognition, especially for its contributions to the recovery work following the Great Hanshin-Awaji Earthquake in 1995. 【Features】 ■ Achieves a large lifting force with a small jack (the wedge effect amplifies hydraulic jack output by 3 to 4 times) ■ Allows for simultaneous lifting and temporary support, enabling safe operations ■ Easily applicable to misaligned girder connections and B.P. shoes ■ No need for special girder reinforcements or lifting brackets *For more details, please refer to the PDF materials or feel free to contact us.
