U-head jack with scaffolding system for supporting slab formwork
A steel base plate is equipped to the tubular (or solid steel rod) screw jack by bolt, with a hole in each corner for securing to mudsill. ACME threads are usually used on the screw jack.
Made from high strength steels, screw jacks are to support and stabilize scaffoldings in construction. It can fit all types of scaffold systems, such as frames, ringlock, or cuplock systems.
There is a notch / cut in the threads of the screw jack to prevent the nut from coming off and to keep the screw jack from being over-extended.
