Further, because pulling the ladder out stretches the bungee cord 123, it is believed that the resistive forces of the bungee cord will help take some of the weight of the ladder thereby making it easier for persons to position the ladder in an operative position.
  • the person may then begin to climb up the ladder 111.
  • the person may grasp the adjacent handle 51b for support, said handle extending outwardly from an end of the container or tank and wherein preferably the base 14 abuts the stop nearest said end.
  • the person is wearing the harness 90 about their waist.
  • the person may secure at least one of the clasps 94 to one of the links 80 or 81. Consequently, should the person slip or loose their balance while climbing over the upper end of the ladder and on to the platform 20, they will not fall to the ground.
  • the person Before placing his or her feet on the upper most rungs of the ladder 111, the person can, by pulling on the locking handle 79, disengage the locking pin 74 and the notches 49d, raise the handle 51b, which itself can be locked in place by releasing the locking handle such that the locking pin engages notches 49b or 49c. By repositioning the handle 51b, which is now higher and is located over and/or closer to the platform 20, it is believed that the person will find it easier to climb on to the platform.
  • the person may, by pulling on the locking handle 79, disengage the locking pin 74 and the notches 49b or 49c, move the post 51 such that it now stands upright, which itself can be locked in place by releasing the locking handle such that the locking pin engages notches 49a.
  • the person In order then to move the support structure 13 along the guide 12 while holding on to the handle 51b for support, the person must pull on the brake handle 72 so as to disengage the jaws 57 and the guide 12. Similarly, in order to prevent further movement of the support structure 13 along the guide 12 the person need only release their grip on the brake handle 72 there permitting the jaws 57 to engage the guide 12.
