The base section for a lifting jack includes upper and lower plates with complementary curved facing and engaging surfaces which allows the barrel of the lifting jack to pivot relative to the ground in use. In a typical lifting jack, the barrel is perpendicular to the ground in use. In the present invention, the base section allows the lifting assembly to pivot relative to the ground up to an angle of 15° from vertical in any direction from vertical.
