The main frame is one of the most important structural components in an aluminum scaffolding system. It forms the backbone of the scaffold tower and supports most of the vertical loads during operation.
For a complete overview of aluminum scaffolding systems, please visit:
The main frame is a welded aluminum structure consisting of vertical tubes and horizontal rungs. It serves as the primary load-bearing component of the scaffold tower.
By connecting with horizontal braces and diagonal braces, the main frames create a complete and stable structure capable of supporting workers, tools, and materials.
Functions of the Main Frame
The main frame performs several important functions:
Supports vertical loads;
Provides structural stability;
Connects horizontal and diagonal braces;
Forms the basic module of the scaffold tower;
Allows height extension through modular assembly.
Without the main frame, a scaffold tower cannot be assembled.
Types of Aluminum Scaffold Main Frames
Standard Frame with Rungs
This design contains only horizontal rungs and is commonly used in vertical ladder towers.
It offers:
Lightweight construction;
Easy assembly;
High compatibility.
