Cup Lock Type System

A multipurpose scaffold system which can be used for all forms of access and support structures in the building and construction industries, ship building, offshore construction and industrial maintenance.
It provides major savings in erection and dismantling times thus minimizing on-site costs. When not in use, its modular construction ensures minimal space requirements for storage.
A unique node point connection allows up to four horizontal members to be connected to a vertical member in one single action - without the use of nuts and bolts or wedges. The locking device is formed by two cups, a fixed lower cup which is welded to the vertical component at pre-located intervals and a sliding upper cup. The forged blade ends of the horizontal components are located into the lower cup, the upper cup is moved down and rotated to secure the components in place and a hammer blow then results in a positive and rigid connection.
It is extremely versatile. It can be erected for straight, curved and circular configuration for both access and support, and also for independent and mobile towers. 
Both vertical and horizontal members are manufactured from 48.3mm overall diameter x 3.2mm gauge high tensile steel to British Standard 4360 Grade 50 
(minimum ultimate tensile stress = 534N/mm2).
With no loose parts and with corrosion protection by hot dip galvanizing to British Standard 729, minimum thickness of the zinc coating is 85 microns.
Conforms to BS1139 Part 5, HD1000, OSHA and Australian New Zealand Standards
