Abstract The present invention primarily relates to the base section 12 for a lifting jack which comprises upper and lower plates 40 and 50 with complementary curved facing and engaging surfaces 44 and 54 which allows the barrel 20 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 12 allows the lifting assembly 14 to pivot relative to the ground up to an angle of 150 from vertical in any direction from vertical.
