发明名称 Compensator system and method for moving construction form tables
摘要 A device for moving construction tables from under poured concrete is disclosed. A spreader bar is suspended from a crane and it incorporates two cables used to connect to the table to be moved at points between the center of the gravity of the table and it's captive end. A hoist is suspended from the spreader bar and it includes two additional cables or chains also used to connect to the table between the center of gravity and the free end of the table.
