Abstract
A jack for lifting an object includes a base assembly and a jacking assembly. The base assembly has a frame with a base member having a nesting chamber, lifting arms pivotably connected to the base member, and a support member for supporting the object. The support member is pivotably connected to the lifting arms and is disposed parallel to the base member. The support member and the lifting arms pivot with respect to the base member into positions including a fully raised position wherein the support member is lifted away from the base member and a fully lowered position wherein the support members and the lifting arms are at least partly nested within the nesting chamber. The jacking assembly is connected to the base assembly for moving the support members and the lifting arms from the fully lowered position towards the fully raised position.
