The quick action drophead supplied complete with nuts and bolts is designed to fit on standard props or adaptors for Cuplocks scaffolding. They allow panels and beams to be struck and re-used after only 3 or 4 days, leaving the support in position for the remainder of the curing period of the concrete slab. The primary head remains in contact with the concrete while the secondary head and its supporting wedge are released by a single hammer blow. The height of the drophead is 214mm and the striking distance allows the beams and panels to drop only 115mm for the their safe removal a marked improvement in terms of speed and safety compared with other systems. The drophead has a load carrying capacity of 40kN. Special care has been taken to ensure that beams cannot be accidentally dislodged once located with the drophead primed.
