Abstract: A pallet lock comprising: (a) a housing including two opposing rails defining a channel therebetween; and (b) a biased double lock at least partially seated within the channel, the double lock repositionable between a pick side blocking position and a load side blocking position, the double lock including a load side portion and an opposing pick side portion, where the pick side portion includes a pick side lock, where the load side portion includes a load side lock, and where at least one of the pick side lock and the load side lock are recessed within the channel as a result of the bias of the double lock.

Abstract: A barrier assembly for protecting an edge of a loading platform includes: a gate reciprocating between a barrier position approximate an edge of a loading platform and an open position away from the edge of the loading platform, and a toe barrier mounted approximate the edge of the loading platform and operatively coupled to the primary gate to reciprocate between a barrier position and an open position. The toe barrier provides a vertical barrier along a floor of the loading platform approximate the edge of the loading platform in its barrier position, and is operative to reciprocate to its barrier position when the primary gate is in its barrier position and to reciprocate to its open position when the primary gate is in its open position.

Abstract: The assembly includes a pair of parallel guide rails, each shaped generally as an inverted U; a first gate segment having at least one pair of rollers positioned on opposite lateral sides thereof, where each roller is received within a respective one of the guide rails so that the first gate segment is guided by the pair of guide rails; a second gate segment having at least one pair of rollers positioned on opposite lateral sides thereof, where each roller is received within a respective one of the guide rails so that the second gate segment is guided by the pair of guide rails; and at least one substantially rigid cross-bar pivotally connected between the first and second gate segments.

Abstract: An elevated loading/conveyor platform includes a generally rectangular knock-over gate positioned in the load-in side opening of the platform structure, where the knock-over gate is pivotally mounted within the load-in side opening and pivotable from a vertically upright barrier position to a generally horizontal loading position. The knock-over gate is biased to the vertical position by a return mechanism, which is designed to return the knock-over gate to its upright vertical orientation when no pallets are being conveyed thereover in the generally horizontal loading position. Preferably, the return mechanism utilizes a spring mechanism (such as gas springs), where the spring mechanism is of sufficient strength to pivot the knock-over gate from the horizontal loading position to the vertical position when no weight or force is being applied to the load-in side of the gate.
