Ergonomic Scaffold System

Excel Modular Scaffold was founded in 1992 when Joe Williams saw the need to improve upon system scaffolds that were in use. The industry had not had any significant advancement in a long period and Williams decided to design the Excel system by calling upon all of his years of experience and expertise. 


Having spent his career in the scaffolding industry, much of it in the refinery and petrochemical market, Williams realized that “time is money”.  He invented the perfect system to increase productivity, while raising the standards for safety with system scaffolding. 


Williams took into account many of the time and money issues he dealt with while using tube, clamp and standard system scaffolding. He had firsthand knowledge of how deck and handrail spacing created issues with meeting OSHA standards, multi-craft scaffolds and less than desirable deck heights. He focused on the cost and time associated with scaffold modifications and the quantity of modifications required with most systems. Williams sought to mitigate the amount of tools and repetitive motions that hand tools required to erect other systems, which put employees at risk for injury, and the racking systems and housekeeping associated with other systems in the yard environment.


As a result, Williams designed a system with a node spacing every 5.75 inches so that decks could naturally be placed vertically at these intervals and eliminate the need for tube and clamp modifications or alterations to a standard scaffold. This node spacing also allows the Excel system to meet both OSHA and Cal/OSHA (California division of OSHA) handrail standards without any modifications necessary.


Next, Williams addressed the amount of tools and striking motions with hand tools that were required to build a standard system. He was able to reduce these actions with the locking trigger mechanism of the Excel system, which allows a horizontal bar to lock onto the two nodes of vertical post without any tools being required. He also streamlined the system and the racks used to transport and hold the system so that the horizontal bars had a precision fit, which reduced clutter and housekeeping issues all while increasing productivity of managing a scaffold yard.


These items alone would allow for a significant savings for Excel customers, but Williams wasn’t finished there. He also designed the system to be stronger with double the weight load capacity of most systems, while maintaining a per piece weight that is comparable to other systems. Excel is also one of the few systems in which the manufacturer has certified the system as an anchorage point to most of its horizontal bars. As a result, the Excel system is second to none in shoring applications.


Williams then began designing and patenting specialty pieces to assist with stairwells, trolley systems, roof adaptors, yo-yo adaptors and many other accessories that allow for unparalleled diversity. These were some of the advancements that first got Bruce Bartlett interested in the Excel System. Today, the Excel system continues to evolve and additional accessories are designed almost constantly to meet the demands of its customers.
