Stair beam


The ladder beam is connected to the vertical and horizontal rods via bowl-type connectors, forming a three-dimensional force-bearing system. The axes of all members intersect at a single point, with nodes lying within the plane of the framework. The connectors exhibit robust mechanical performance—resisting bending, shear, and torsion—ensuring that the overall structure is stable and reliable, while also providing a load-carrying capacity approximately 15% higher than traditional cup-lock scaffolding systems.

Erect the pole and secure the bowl.


Spiral locking: The upper bowl clamp features a spiral locking mechanism that, when rotated, tightly engages with the positioning pin, creating a robust mechanical interlocking force to ensure a secure connection between the crossbar and upright post.

Set up the pole and place the bowl beneath it


The lower bowl clamp is directly welded to the designated position on the upright post, creating a stable bowl-shaped groove that serves as the supporting base for the crossbar inserts.
