Abstract: A universal, portable base for heavy equipment, such as pump jacks, has a substantially rectangular slab of reinforced concrete with three rails extending longitudinally from end-to-end thereof substantially equally spaced apart. Anchor slides fit over the rails and can be moved along the rails to appropriate positions for receiving tie-down devices for securing heavy equipment to the base.The base includes networks of reinforcing steel bars extending longitudinally and transversally of the base intermediate its thickness with one network being secured to the longitudinal rails.
