Employees suggested the idea for the platforms at safety committee meetings. Prior to these stands we had to use lift trucks or rented scissor-lift equipment to access the outboard wing areas. Small ladders may still be needed occasionally, but the half dozen that were constantly beneath the wing have been removed. That means no more climbing up and down for tools and parts, because everything they need is at their fingertips on the platform, including lighting and high-pressure air and electrical systems, which are plumbed into the wing docks. Another benefit is that the floor is rid of cords and hoses yet another improvement for safety.
Ladders are hard on the feet and the back.
So this makes life much more comfortable.
