We developed a new maintenance jack used for a lift-up test of earth anchor. This machine jack is small and lightweight and it is easy to set it for the lift-up test. The liftup load obtained by lift-up tests using the new maintenance jack was the same value obtained by using a center hall jack. However the lift-up displacement obtained by the tests with the center-hall jack was larger than the displacement obtained with the new maintenance jack because of extension of tension-bar used for center hall jack. This new maintenance jack proposed in this paper can be convenience and can increase accuracy of lift-up tests.
