Wall-climbing concrete form lifting system
A self-climbing concrete wall form hoist for forming a concrete wall section atop a previously formed wall section has a wall mounting releasably secured to the previously formed wall section, a plurality of moveable vertical masts, an extendable cylinder inside each mast, and a platform alternatively supported on the masts, which in turn are supported alternatively on the upper and lower wall mountings. The apparatus cycles between a platform raising position when the masts and platform are supported on the upper wall mounting and a lower wall mounting raising position when the masts and platform are supported on the upper wall mounting. The extendable cylinders are extended to raise the mast and platform relative to the lower wall mounting when the masts are supported on the upper wall mounting, and the extendable cylinders are retracted when raising the lower wall mounting relative to the platform when the masts and platform are supported on the upper wall mounting. The self-climbing concrete wall form hoist can descend a wall by effectively reversing the steps required to complete wall climbing.
