A load carrier for loading and unloading a container includes rigid load-carrier segments, each having a length and width in first and second directions, respectively, and an upper side in a third direction. In a first state, the upper sides are parallel to one another and, in the first direction, one behind the other, to form a planar loading surface. The segments are mutually connected in an articulated manner such that they are pivotable to one another about pivot axes parallel to the second direction. In the first state, a respective segment which, in the first direction, follows a respectively other segment, is pivotable, by its upper side, toward the upper side of the other segments, so that, by the segments being rolled up in spiral form, the load carrier is transferrable from the first into a second state and, by unrolling, is transferrable back into the first state.

According to an example aspect of the present invention, there is provided a hauling beam, which can be placed in connection with, a load to be moved, so that by moving the hauling beam the load can be moved. The hauling beam can be moved, for example, by dragging. The hauling beam described herein makes it possible to lift the load to be transferred on the rollers, wheels or rolls and to transfer the load by means of them. The hauling bean further comprises a spring retainer having a body with at least one mounting block attached to at least one of the parallel slats, a slide mounted on the body and a spring retained between the slide and a detent on the body, wherein the slide is attached to the support beam, a chain running as a loop around chain sprockets at each end of the hauling beam, one end of the chain being connected to the slide and one end connected to the body of the spring retainer, and an actuator configured to move one of the sprockets in the longitudinal direction of the chain.

The apparatus comprises a rotary put wall having a plurality of totes. The apparatus further comprises a vertical reciprocating conveyor (VRC) placed within the rotary put wall. The internal vertical reciprocating conveyor (VRC) comprises a plurality of chutes to receive one or more items from a robotic device. The internal vertical reciprocating conveyor (VRC) is further configured to be rotatable with respect to the rotary put wall and to convey the one or more items into one tote of the plurality of totes of the rotary put wall.

The invention relates to a slat for a reciprocating slat conveyor, where the slat comprises an elongated slat body having an upper surface configured for supporting a load placed on the slat, a bottom surface, opposite to the upper surface, a first side surface and a second side surface, opposite to the first side surface, wherein at least one of the upper surface, bottom surface, first side surface and second side surface is at least partially provided with a wear member.

The invention relates to a reciprocating slat conveyor multiple parallel slats that are slidable in the longitudinal direction, wherein the slats comprise subsequently alternating a first slat and a second slat, wherein the first slats comprise a horizontal upper wall section and an upright end wall section, and wherein the second slats comprise a horizontal upper wall section and a vertically upright wall section, wherein the upright wall section outwardly merges into an overhanging wall section that extends over the end wall section of the adjacent first slat, wherein the overhanging wall section merges into a vertically downwardly pending end wall section that extends aside the end wall section of the adjacent first slat, wherein a seal is present between the upright wall section and the end wall section of the second slat.

A conveyance method of conveying a conveyance target object by loading the conveyance target object on a slider, wherein the slider is connected to a ball nut threadably engaged with a ball screw shaft, includes a step of rotating the ball screw shaft by an electric motor, a step of applying a braking force which is a rotation resistance to the ball screw shaft by a non-electric resistance changing unit, and a step of setting at least one of a driving force of the electric motor and the braking force of the resistance changing unit so that the slider will stop when a predetermined external force acts on the slider during conveyance and changes the slider to an overload state regardless of the presence/absence of the conveyance target object loaded on the slider and a weight of the conveyance target object.
