An L-shaped track has a vertical part configured to stand on the ground, a horizontal part configured to span over a roof, and a curved part in between. A motor-driven winch moves a carriage up and down the track. The carriage engages a skylight, which can be quickly and easily hoisted from the ground to the roof up the track to the roof to install the skylight.

A system includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the system can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.

A product transport and storage apparatus is disclosed in the form of bots which aid human activity. The invention makes the human activity less strenuous, more efficient and more productive. A primary field of use is urban and suburban food distribution. The Product Transport and Storage system comprising a truck with a truck trailer, at least one Porch Bot placeable in the truck trailer to store and transport cases of groceries, a Railed Crane Bot apparatus connected to a roof of the truck trailer to lift and place the Porch Bot(s) at least within the truck trailer, an elevator bot enabling Porch Bots to be loaded and unloaded from a truck, and a Mother Bot having a platform which is moveable vertically and horizontally to transport the Porch Bot(s) to and from the truck trailer to a porch, patio, or landing.

An automated storage and retrieval system includes a storage array of storage locations for case units. An in-out case conveyor is capable of bi-directionally transporting case units to and from the storage array, and an in-out loaded pallet conveyor is capable of bi-directionally transporting loaded pallets towards and away from the storage array. A palletizer-depalletizer cell includes a bi-directional pallet transport system with more than one independently driven pallet transports, each with a different pallet holder independently movable relative to a cell frame. Placement of case units commissioning a pallet layer loading a pallet, and removal of case units decommissioning a pallet layer unloading another pallet are both effected at the common pallet layer interface at a predetermined level of the cell frame. The pallet transports independently index a first and a second of the different pallet holders, each independently holding the pallet loading at the common pallet layer interface.

A vehicle assembly according to an exemplary aspect of the present disclosure includes, among other things, a cargo bed of a vehicle and a crossbar spanning the cargo bed. The crossbar is slidable relative to the cargo bed. A lift assist device is mounted to the crossbar. The assembly can include a passenger side rail mounted to a passenger side wall assembly of the cargo bed, and a driver side rail mounted to a driver side wall assembly of the cargo bed. The crossbar can be slidably coupled to both the driver side rail and the passenger side rail.
