Avenger Vertical Carousel Arm Assembly Is Superior? 

The Avenger vertical carousel arm design eliminates the number one historical vertical carousel failure point. The Avenger uses a patent pending double reinforced arm and forging assembly that attaches to the chain singularly, which avoids costly cascading failures.
Other vertical carousels utilize a single scissor arm design. The Avenger's scissor arms are double reinforced.
Other vertical carousels use a simple pin to attach the arms to the rollers which run in the guide track. In comparison, the Avenger uses a forging.
Lastly, other vertical carousels will use one hole in the chain to support an arm for two carriers. If there is any disturbance or pressure on the arms it will typically bend or destroy multiple arms in a cascading effect. The Avenger's double reinforced arms attach to the chain in a single position. If there was any pressure or stress, it is not passed through. This eliminates the cascading effect.
