AI Technical Summary

Technical Problem

Existing lightweight scaffolds require frequent repositioning, leading to reduced productivity and increased injury risk due to the need for workers to climb on and off the scaffold during tasks like painting, and existing multi-function scaffolds with multiple ladder frame types complicate inventory and reconfiguration.

Method used

A connectable, multi-function scaffold design using only walkthrough ladder frames with detachable rungs that can be removed to allow unobstructed movement between scaffolds and simplified reconfiguration, reducing the number of parts and inventory costs.

Benefits of technology

Enhances worker safety and productivity by enabling seamless movement between connected scaffolds without obstruction, while reducing the complexity and cost of scaffold reconfiguration.

Abstract

An improved multi-function scaffold connects end-to-end with similar scaffolds to provide a longer working surface. The scaffold includes two walk-through ladder frames with detachable rungs. When two scaffolds are joined, the detachable rungs on the ladder frame between the joined scaffolds can be removed to enable workers to move freely between scaffolds without obstruction.
