mechanical ram that is used in both positioning the outrigger and the crane arm. ## Claims ### Claim 1 A container trailer having a lifting apparatus, the lifting apparatus comprising a base, a crane arm, an outrigger, and a mechanical ram wherein the mechanical ram is used to position both the outrigger and the crane arm, the crane arm having a lifting end and a pivot end, the pivot end pivotally attached to the base such that the lifting end of the crane arm can be raised and lowered under force of the mechanical ram. ### Claim 2 (depends on 1) The container trailer of claim 1, wherein the crane arm can be lengthened and shortened through an extendable and retractable extender. ### Claim 3 (depends on 1) The container trailer of claim 1, including a locking hole and an engagement pin, the crane arm having a locked position and an unlocked position, in the locked position the engagement pin is engaged in the locking hole and in the unlocked position the engagement pin is not engaged in the locking hole, in the locked position extension of the mechanical ram lowers the outrigger and retraction of the mechanical arm raises the outrigger, in the unlocked position retraction of the mechanical arm draws the crane arm toward the outrigger and extension of the mechanical arm rotates the crane arm from the outrigger. ### Claim 4 (depends on 3) The container trailer of claim 3, wherein the outrigger has a leg, the outrigger having a raised position and a work position, in the raised position the outrigger is lifted, in the work position the outrigger is lowered and the leg is engaging the ground. ### Claim 5 (depends on 2) The container trailer of claim 2, wherein the extender is extended and retracted by electrical action, the electrical action including an electric solenoid valve controlling movement of the mechanical ram. ### Claim 6 (depends on 1) The container trailer of claim 1, wherein the mechanical ram is selected from a broad group of hydraulic cylinders, linear actuators, turnbuckles, and any combination thereof. ### Claim 7 (depends on 1) The container trailer of claim 1, wherein the base of the lifting apparatus can rotate to enable the crane arm to lift items to the left of the trailer, to the right of the trailer, behind the trailer, to the left and behind the trailer, and to the right and behind the trailer. ### Claim 8 (depends on 1) The container trailer of claim 1, wherein the outrigger has an outrigger extender that is extendable and retractable. ### Claim 9 (depends on 1) The container trailer of claim 1, having a front and a back wherein the trailer has more than one lifting apparatus with at least one lifting apparatus in the back and at least one lifting apparatus in the front, the at least one lifting apparatus in the back and the at least one lifting apparatus in the front constructed and arranged to be secured to the back and the front of a container and lift and load the container onto the trailer. ### Claim 10 (depends on 3) The container trailer of claim 3, including more than one locking hole, the crane arm having a locked position and an unlocked position, in the locked position the engagement pin is engaged in one of the plurality of locking holes and in the unlocked position the engagement pin is not engaged in one of the plurality of locking holes. ### Claim 11 A container trailer having a front and a back, and having a front lifting apparatus and a back lifting apparatus, each of the lifting apparatuses comprising a base, a crane arm, an outrigger, and a mechanical ram wherein the mechanical ram is used to position both the outrigger and the crane arm, the crane arm having a lifting end and a pivot end, the pivot end pivotally attached to the base such that the lifting end of the crane arm can be raised and lowered under force of the mechanical ram. ### Claim 12 (depends on 11) The container trailer of claim 11, wherein the crane arm can be lengthened and shortened through an extendable and retractable extender. ### Claim 13 (depends on 11) The container trailer of claim 11, wherein each lifting apparatus includes at least one locking hole and at least one engagement pin, the crane arm having a locked position and an unlocked position, in the locked position the at least one engagement pin is engaged in the at least one locking hole and in the unlocked position the at least one engagement pin is not engaged in the at least one locking hole, in the locked position extension of the mechanical ram lowers the outrigger and retraction of the mechanical arm raises the outrigger, in the unlocked position retraction of the mechanical arm draws the crane arm toward the outrigger and extension of the mechanical arm rotates the crane arm from the outrigger. ### Claim 14 (depends on 13) The container trailer of claim 13, wherein the outrigger of each lifting apparatus has a leg, the outrigger having a raised position and a work position, in the raised position the outrigger is lifted, in the work position the outrigger is lowered and the leg is engaging the ground. ### Claim 15 (depends on 12) The container trailer of claim 12, wherein the extension of each lifting apparatus is lengthened and shortened by a hydraulic mechanical ram. ### Claim 16 (depends on 11) The container trailer of claim 11, wherein the mechanical ram is selected from a broad group of hydraulic cylinders, linear actuators, turnbuckles, and any combination thereof. ### Claim 17 (depends on 11) The container trailer of claim 11, wherein the base of the back lifting apparatus can rotate to enable the crane arm to lift items to the left of the trailer, to the right of the trailer, behind the trailer, to the left and behind the trailer, and to the right and behind the trailer. ### Claim 18 (depends on 11) The container trailer of claim 11, wherein the outrigger of each lifting apparatus has an outrigger extender that is extendable and retractable.
