What is cuplock scaffolding?

Cuplock scaffolding is a modular system whose standards carry cup joints at fixed intervals: a sliding top cup locks up to four ledger blades at one node, without loose wedges or couplers. ScaFix models 5 systems of this type from 4 manufacturers, with bay lengths from 0.91 m to 3.05 m.

Parts on the same example house

The systems of this type with a page of their own, each planned on ScaFix’s example house (11.4 m × 5.3 m) with the default settings, fewest parts first. Totals differ with bay length, depth and part design; a lower total says nothing about price or load class. The setup is on the methodology page.
System	Long-wall bays	Depth	Parts in total
StepUp Cuplock	5	1.22 m	573
Excel Modular Scaffold	5	1.22 m	581
Acrow SUPERCUPLOK	5	1.27 m	589
Cuplock	6	1.3 m	603

Questions and answers

How many cuplock scaffolding systems does ScaFix model?

5 systems from 4 manufacturers: Acrow, Excel, SGB and StepUp Scaffold.

Which cuplock scaffolding system needs the fewest parts on the example house?

StepUp Cuplock, with 573 parts, against SGB CUPLOK with 651, on the same 11.4 m × 5.3 m house. The difference comes from bay length, depth and part design; it says nothing about price or load class.

Which bay lengths are most common for cuplock scaffolding?

3.05 m (offered by 2 systems), 3 m (offered by 2 systems) and 2.5 m (offered by 2 systems). The catalogue holds each system’s own lengths, and ScaFix fills a wall with them.
