A method for setting an adjustable height upper pulley on a tall structure; load transfer from a suspended load to a tall structure; fan-based stabilizer; stabilizer or horizontal load position control mechanism using a closed loop of cable and taction winch for a crane application; crane-based lifting system that uses a closed loop of lifting cable looped around a traction winch; and a stabilizer or horizontal load position control mechanism that does not need a closed loop of cable. Other embodiments are also described and claims. Other embodiments are also described and claimed. ## Claims ### Claim 1 A crane lifting system comprising: an extension section supported on a vehicle, the extension section being selected from the group consisting of a crane boom and a ladder; a first upper pulley directly attached to the extension section at a position proximate to a highest elevation of the extension section; a second upper pulley directly attached to the extension section at another position proximate to the first pulley and near said elevation; a lifting winch; a lift cable that is looped around the first upper pulley and the lifting winch; a load directly attached to a hook block, wherein the hook block is directly attached to an end of the lift cable; a stabilizer cable having a first end and a second end, wherein the first end is directly attached to the hook block proximate to the end of the lift cable, wherein the second end of the stabilizer cable is directly held by a drum winch, the drum and lifting winches are supported on the vehicle, and the stabilizer cable is looped around the second upper pulley; wherein the lifting winch is configured to rotate in a first direction to raise the load, and the lifting winch is configured to rotate in an opposite second direction to lower the load; a sideways adjustment winch directly attached to the hook block; an adjuster cable directly held by the lateral adjustment winch at a first end of the adjuster cable, directly attached to a traveler pulley at a second end of the adjuster cable, and having a traveler extent which occupies a space positioned an entire length between the second upper pulley and the drum winch; and, wherein the traveler pulley is configured to automatically and simultaneously ride along substantially the entire length of the traveler extent of the adjuster cable as a direct result of the load being raised and lowered. ### Claim 2 (depends on 1) The system of claim 1, further comprising a pillow configured to be positioned between a structure and the extension section to spread a second load formed by the extension section during raising and lowering of the load directly attached to the hook block. ### Claim 3 (depends on 2) The system of claim 2, wherein the pillow is in contact with a tip of the extension section, and the pillow is configured to lean against the structure during raising and lower of the load directly attached to the hook block. ### Claim 4 (depends on 1) The system of claim 1, wherein the sideways adjustment winch is configured to a) pull the adjuster cable to thereby pull the traveler pulley and the load sideways towards each other, and b) let out the adjuster cable to allow the load to move sideways away from the traveler pulley. ### Claim 5 (depends on 1) The system of claim 1, wherein the sideways adjustment winch is configured to move up and down automatically with the load, as the load is raised and lowered through operation of the lifting winch. ### Claim 6 (depends on 1) The system of claim 1, wherein the extension section is configured to extend over a top of a structure in order to spread another load formed by the extension section during raising and lower of the load directly attached to the hook block. ### Claim 7 (depends on 1) The system of claim 1, wherein the sideways adjustment winch is a remotely operated winch. ### Claim 8 (depends on 7) The system of claim 7, wherein the remotely operated winch is configured to operate in a first direction to increase a tension on the adjuster cable in order to cause the load to be pulled toward the stabilizer cable.
