Self-Lubricating Scissor Arm Wheels Extend Life of Avenger Vertical Carousels

Self-lubricating wheels on the scissor arm assemblies of Sapient Automation Avenger vertical carousels help extend its operational life in storage and retrieval applications while reducing maintenance costs.

Generally, vertical carousels require periodic lubrication as part of a preventive maintenance routine to ensure reliable operation. Self-lubricating scissor arm wheels reduce maintenance downtime and extend service life. This is particularly valuable during busy times when the unit is accessed more than normal and if the unit is overloaded. Likewise, the new wheel is valuable in providing quiet run time when compared to other metal, plastic, and non-petro-based materials.

The self-lubricating wheel is a new component in the Avenger vertical carousel's scissor arm design to provide higher levels of reliability. Instead of using a single scissor arm design, the Avenger carousel's scissor arms are double reinforced. Instead of using a pin to attach the arms to the rollers in the guide track, the Avenger arm's use a forging for maximum reliability.

The Avenger vertical carousel's arms mount to the chain in their own position. If there is any pressure or stress, it is not passed through to the other arms. This eliminates the potential for any cascading effect and unit failure. When the arms design is combined with the new self-lubricating wheels, the reliability factor is increased.

The Avenger vertical carousel consists of rotating shelves that move up or down in response to operator commands, delivering items at an ergonomically positioned window for easy removal. Vertical design maximizes the use of overhead space and can recover up to 75 percent of the floor space required for traditional rack and shelving systems.
