Abstract: A rail system and transfer vehicle for a storage retrieval system. The rails are fabricated to include a vehicle support surface that supports a transfer vehicle, a load support surface that supports the skid, tote, vessel, or pallet to be stored, a spacing surface that defines the distance between the load support surface and the vehicle support surface. Attached to the load support surface is an alignment surface that extends upwardly at an angle between 40 and 80 from the horizontal. When a misaligned pallet is lowered, it first contacts the alignment surface and as it continues to be lowered, interaction between the alignment surface and the misaligned pallet causes the pallet to move into alignment with the rail system before coming to rest on the load support surface. The rail system can be used in conjunction with a high weight capacity transfer vehicle. Load lift is provided by a plurality of interconnected screw jacks.

Abstract: A rail for a track-bound vehicle comprising a number of lateral flanges, which can cooperate with a substructure, the flanges extending in an outwards direction from an essentially vertically arranged web provided with a foot, and a portion of a runway rail forming part of a head of the rail and connected with the web. This makes possible a reduction of excavating and substructure work, when laying rails, and a simplified maintenance of the tracks, and in addition also reduces the required number of sleepers. The lateral flanges as seen in the transverse direction relative to the web project to a larger extend than the foot, so that the load operating on the rail will essentially be absorbed by the substructure cooperating with and substantially being located in the area of the lateral flanges.

Abstract: The present invention relates to a rail intended to constitute a tread for heavy duty rolling stock, such as gantry cranes, mounted on wheels or rollers and concerns more specifically a guide rail on which both center-flange wheels or rollers, and lateral-flange wheels, as used on railway lines roll, comprising, in section, two integrally formed spaced heads running parallel to each other, the two heads having vertical inner side walls and being separated by a horizontal intermediate channel whose bottom constitutes a horizontal connecting strip.
