ABSTRACT OF THE INVENTION A method and apparatus for forming poured concrete walls using crane-lifted type jump scaffolding optionally including associated wallforms, and particularly including a unique auto- matic safety lock system keyed to the lifting operation to anchor and secure the scaffolding to the previously poured shearwall. This latching system allows for safe and efficient placement of the scaffolding and eliminates the need to have workmen present on unlocked scaffolding, and especially removes the reason for workmen to be tempted to ride the scaffolding while it is being lifted.
