on its other end which can also serve as a handle for use by the top worker the top worker may use this push rod to raise the loop 64 above the coupling pin 30 39 so as to disengage the rope 54 from the side frame 12 39 as is illustrated in fig5 and 6 of the drawings thus it is not necessary for the top worker to climb up a portion of this end frame 12 39 in order to reach the loop 64 with his hand the push rod has a second important function to perform namely to assist in shifting the position of the platform 40 as will be described with relation to fig4 and 7 notice in fig4 that a small hole 94 is shown in the end of the platform 40 near where the platform stops short of the bottom rail 22 the hook formation 92 of the push rod 88 is capable of engaging under the edge of the platform and to be hooked into the hole 94 as is best seen in fig7 once the push rod 88 is hooked into one end of the platform 40 the top worker would move to the opposite end of the platform and while standing on the end frame 12 would grasp the end of the platform and tend to raise that end of the platform while the ground worker will be pulling on the rope so as to lift the opposite.
