Abstract

Twinned circular, parallel arrays of spoke-like second-class levers (10, 12) enclosing a centered cargo cradle for towing 2½ ton stone blocks (26) up a stepped structure of stone courses (34) by rotation of the whole.

Claims

1. A crawler climber used to transport a stone block upwards on a stepped structure made of similar sized stone blocks comprising:

two spoked arrays, each array comprising;

six levers, each fastened to a first and a second reinforcing hub plate by pegs;

a peg being fastened in place near the end of each lever for use in fastening and releasing rope yokes for a step by step advancement of the crawler climber up the side of the structure;

a stone block lashed between the two arrays via a rope or rawhide lashing;

wherein the levers are pivoted up the structure in relation to each other to fit succeeding levers into succeeding interior corners of the structure in order to transport the stone block up the side of the structure.
