Technofast EziJac hydraulic tensioners

Technofast EziJac tensioners are designed to increase joint security and durability on machinery and engines for equipment including wind turbine foundations, cranes, slew bearing applications, engine re-builds for Caterpillar, Hitachi, Komatsu, Hastings Deering and HE Parts, and for Liebherr equipment, including their large cranes and mining machinery.

The tensioners are designed to reduce set-up times and eliminate tool selection complexity by precisely tensioning RMS and RMZ hex nuts using the corresponding bridge piece (2.0 fine pitch) stud puller and nut rotator. EziJacs incorporate compact high-pressure hydraulics to tension bolts to the exact load required to help ensure optimum life and maintenance-free performance, thereby reducing downtime and OH&S risks involved in servicing heavy machinery.

The integrated EziJac nut capacity, with precise dual thread puller functionality, is intended to deliver a complete system to end users, meaning less tooling is required to complete complex tasks quicker, safer and more efficiently. Rated at 627 kN, the tensioners have higher kN ratings than standard comparable fasteners and, in addition to M30 nuts, can also handle M27 and M24 installations.
