An automated system structure is disclosed which may be quickly and efficiently assembled using a number of storage modules. Storage modules may be comprised of a pair of shelf modules, each comprising a number of defined storage locations for storing totes, cartons, trays or other containers. The shelf modules may themselves be modular units comprising a number of horizontal storage levels affixed to a pair of vertical support assemblies at each end of the shelf modules. The pair of shelf modules may be accurately spaced from each other by mounting the shelf modules to tie beams at the bottom and tie plates at the top.

Goods storage and retrieval systems and materials handling vehicles are provided. The goods storage and retrieval system includes a multilevel warehouse racking system; a materials handling vehicle comprising a mast assembly, a picking attachment, and vehicle-based cart engagement hardware; a mobile storage cart; and a transporter comprising transporter-based engagement hardware. The transporter-based engagement hardware enables the transporter to engage, transport, and disengage the mobile storage cart. The vehicle-based cart engagement hardware is coupled to the mast assembly to (i) engage and disengage the mobile storage cart and (ii) transport the mobile storage cart to multiple levels of the multilevel warehouse racking system. The mast assembly and the picking attachment are configured to access multiple levels of the multilevel warehouse racking system. The picking attachment is configured to transfer totes between the multilevel warehouse racking system and the mobile storage cart.

A pallet storage system and method are provided. A rack for storing pallets loaded with goods is constructed with a corresponding pair of left and right rails. Carts for supporting the pallets ride on those rails. The rails can have an I-beam shape cross section, include a lower horizontal wall, a vertical wall extending up from the lower horizontal wall and an upper horizontal wall at the top of the vertical wall. The lower and upper horizontal walls include an outer flange extending from the vertical wall in a sideways direction away from the corresponding other rail and an inner flange, extending sideways towards the corresponding other rail. The carts can nest, until loaded and the front of the carts can be flush at the front of the rack.

A method and a system for transporting inventory in a storage facility is provided. The system includes an inventory storage unit (ISU) and a transport vehicle. The ISU includes a base shelf, and a plurality of support plates mounted below the base shelf. The transport vehicle includes a top plate and a control device that controls movement of the top plate. Upon actuation of an interlocking mechanism of the transport vehicle that is aligned beneath the ISU, the top plate is lifted to a first height and then rotated for engaging the top plate with the support plates of the ISU. The engaged top plate is further lifted to a second height to lift the ISU off the work floor of a storage facility. Upon lifting the ISU, the transport vehicle transports the ISU to another location in the storage facility.

A system for removing, storing and precisely re-installing removable automobile doors. This system includes a mobile base for positioning near the vehicle and moving stored doors to their storage location. The base of this system provides mounting positions for 2 or more lifting/storing/re-installation devices, accommodating full service (removal, storage and re-installation) of up to 4 doors at once. The lifting/storage/re-installation devices contain full 3 axis precise adjustment and rigid coupling to each of the vehicle's doors. Without this precision, the weight and non-balance of removing/re-installing the doors can cause the door to tilt into or away from the vehicle, possibly crushing a human body part (finger, hand) and/or damaging the vehicle or door. By rigidly coupling the door to the precisely adjusted device, precise vertical lifting and lowering may be used to remove and re-install the doors, including accommodating surface variations encountered from removal to re-installation time.

A storage system includes a rack with a plurality of layers, each layer including an aisle and a plurality of rows extending from the aisle defining storage locations for items. A shuttle usable with the rack includes a first cart movable along the aisle and a second cart configured to be carriable by the first cart and to be movable along a row. The second cart is configured to carry an item between the first cart and the storage locations. A conveyor is located on one of the first or second carts to move the item onto or off the first cart. Related methods of storing and/or retrieving items from a rack are also disclosed. A rack system is disclosed and is readily assembled without welding, transferring loading so that the weight of the rack and any item stored therein is supported by the upright elements via support brackets.

An apparatus (10, 60) for storage of elongate elements, such as pipes, tubes and conduits. The apparatus (10, 60) includes a frame (12) that supports a plurality of trays (15, 63). The trays (15, 63) are arranged in two vertical columns of storage positions, except for the trays located at the top or bottom of the apparatus as they are moved about sprockets (71, 72) by a drive motor (73). Each tray (15, 63) is configured to support a plurality of elongate items. The trays (15, 63, which may embodied as cradles or racks, may be moved between a storage position and an access position, wherein in the access position, the elongate items can be accessed from substantially vertically above the tray (15, 63).

A maintenance system is disclosed for assisting in maintaining an automated carrier system for moving objects to be processed. The maintenance system includes a plurality of automated carriers that are adapted to move on an array of discontinuous standard track sections, each said automated carrier including a carrier body that is no larger in either a length or width direction that a standard track section, and an automated maintenance carrier that is adapted to move on the array of discontinuous track sections, said automated maintenance system including a maintenance body that is larger in at least one of a length or width direction than the standard track section.

Systems and methods directed to shelving systems include a frame and one or more translatable shelves. The shelves are supported on rails and are horizontally translatable from a rearward position to a forward position. When adjacent shelves are respectively most rearward and most forward, certain shelf and frame structural cooperation enhance shelf access and shelf removability. Provided a single shelving kit, certain shelf configuration may be customized for particular end uses.
