  • Lift mechanisms for mobile drive units having improved serviceability and durability
    Patent number: 12649404

The lift mechanisms may comprise various improvements for serviceability and durability of the mobile drive units. For example, various service access ports for maintenance of the lift mechanisms may be configured for quick and easy access, one or more cover plates may be designed for quick and reliable coupling and decoupling from the lift mechanisms, and a central cover of the lift mechanisms may be configured to channel liquids down and away from the lift mechanisms, thereby facilitating simpler and faster maintenance and improved durability of the lift mechanisms.
