and third 70 support portions falling back into a nested position within the first support portion 50 via the force of gravity removal of the support pins 68 a 68 d thus permits the piston rod 37 a of the hydraulic cylinder 36 a to then be extended the desired distance such that the support portion engaging unit 42 draws the lower portions 72 a 72 d lower portion 72 a not shown in the figures of the respective vertical beams 62 a d upward an equivalent distance because the vertical beams 62 a 62 d rest at the bottom of the respective ground engaging portions 56 a 56 d the vertical beams 62 a 62 d are approximately the same length as the respective ground engaging portions 56 a 56 d and full extension of the vertical beams 62 a 62 d almost doubles the height of the tower 10 thereby allowing the tower 10 to support a load that is located significantly higher than the height of the tower 10 when the vertical beams 62 a 62 d are at the bottom of the respective ground engaging portions 56 a 56 d conversely because the height of the tower 10 when the vertical beams 62 a 62 d are at the bottom of the respective ground engaging portions 56 a 56 d is only about half the height of the tower 10 when the vertical beams 62 a 62 d are fully extended from the respective ground engaging portions 56.
