Abstract: A concrete form suspension system has a form support projecting laterally from an upper portion of a vertically displaceable support structure and a hydraulic jack operable to raise the support structure along a vertically extending concrete structure. A support device can be secured to the concrete structure for supporting the jack and support brackets can be secured to the concrete structure for supporting the raised support structure from the concrete structure. By operation of the jack, the support structure can climb the concrete structure to allow concrete forms suspended from the form support to be located in position for use in upwardly extending the concrete structure.

Abstract: A flying form table truss having web members interconnecting top and bottom chords includes screw jack legs adjustable independently of the web members along the bottom chord. Each screw jack leg has a screw jack and a ground engagement member at one end of the screw jack leg, and is connected by a pivot connection to a readily releasible fastening mechanism provided at the opposite end of the screw jack for securing the screw jack leg to the bottom chord. The fastening mechanism comprises at least one fastener for tightening the fastening mechanism against the bottom chord to secure the screw jack leg in position on the bottom chord.
