Definitions

  • the present invention pertains to a system for transferring freight containers to and from a railway freight car, in particular between a truck and a railway freight car (see, for example, US 2 294 928 A , corresponding to the preamble of claim 1).
  • Another container transfer system employs a swivel function.
  • a swivel function is for example described in WO 2005/097 575 A1 , which utilizes a special railway wagon having a so-called swap body, which may be swiveled to one of the sides of the wagon. The container is then transferred end-wise to this swap body, after which it is swiveled back to the special railway wagon.
  • the swap body In order to support the swap body when it is swiveled away from the train wagon, the swap body is equipped with a number of supporting legs.
  • this and similar systems are commercially available, they are not widespread, because terminal investment costs are huge attributable to the need for providing a special railway train wagon having this swivel functionality. Furthermore it requires an extensive parking area which must be able to accommodate a large number of trucks.
  • transfer wagon by which containers may be transferred from a warehouse to a railway freight car, or vise versa.
  • the transfer wagon is placed on a railway track alongside the railway track, on which the freight train is placed, and the containers are transferred sideways to and from the freight cars.
  • a transfer vehicle for transferring a freight container from a railway flatcar horizontally and sideways onto said transfer vehicle.
  • the bottom of the transfer vehicle can be lowered, and the container can roll of the transfer vehicle along the longitudinal direction of it.
  • EP 2 108 605 A1 shows a freight container, which is transferred horizontally and sideways directly from a railway freight car and a truck.
  • WO 96/02445 A1 a method and device for transferring a freight container from a railway freight car to a truck.
  • the transfer device is placed on a truck, and it comprises a telescopically extendable arm, which like the forks of a forklift is extended and placed under a container to be transferred.
  • the system employs special twist locks, which may be lowered (vertically movable) when the arm is placed under the container, whereby the container will be free to move horizontally from the railway freight car to the truck.
  • a transfer system for horizontally and transversally transferring a freight container between a railway freight car and a vehicle, said transfer system being placed on said vehicle and comprising at least two grabber arms which are movable only in a direction transversal to the longitudinal extension of said vehicle into openings in a frame placed under the freight container, wherein the movement of each of the at least two grabber arms is accomplished by an endless chain which is driven by a drive wheel that cooperates with said chain, and which is operatively connected to a drive motor, and in that two tensioner wheels are placed at each side of said drive wheel, characterised in that each of the tensioner wheels are hinged to a shaft, which is tensioned by a spring force or hydraulic cylinder and piston means, said tensioner wheels cooperating with the chain in such a way that one or the other tensioner wheels causes a tightening of the chain in dependence of whether the chain or both the chain and the grabber arm is/are driven in one or
  • a transfer system is achieved wherein the grabbing arm can move in two opposite directions, without risking losing the chain, which could otherwise fall off the drive wheel when the chain is driven in the opposite direction.
  • This situation is, however, precluded by letting the two tensioner wheels cooperate with the chain in such a way that one or the other tensioner wheel causes a tightening of the chain in dependence of whether the chain, and thereby the grabber arm, is driven in one or the other direction.
  • a transfer system that may be used regardless of which of the two sides of the vehicle that faces the railway freight car, because it is possible to move the grabber arm in both directions by the claimed transfer system. This greatly increases the flexibility of the system as compared to those known in the art.
  • intermodal container indicates that the container can be moved from one mode of transport to another (from ship, to rail, to truck) without unloading and reloading the contents of the container, each of which has a unique ISO 6346 reporting mark.
  • the container capacity is often expressed in twenty-foot equivalent units (TEU), which is a unit of capacity equal to one standard 20 ft ⁇ 8 ft (6.10 m ⁇ 2.44 m) (length ⁇ width) container.
  • a typical container has doors fitted at one end, and is constructed of corrugated weathering steel.
  • the containers are typically 8 feet (2.44 m) wide by 8 feet (2.44 m) high, and either a nominal 20 feet (6.1 m) or 40 feet (12.19 m) long. They could be stacked up to seven units high. At each of the eight corners are castings with openings for twistlock fasteners.
  • the "pallet wide” containers are about 2 inches (5 cm) wider than standard containers to accommodate for Euro-pallets common in Europe. These containers feature an internal width of 2440 mm for easy loading of two 1200 mm long pallets side by side-many sea shipping providers in Europe allow these, as overhangs on standard containers are sufficient and they fit in the usual interlock spaces. With the same floor panel, the side ribs of pallet-wide containers are embossed to the outside instead of being molded to the inside.
  • a freight car By a freight car is meant a railway wagon configured to transport a standard shipping container. These freight cars could also be ordinary flat cars equipped with twistlocks accommodated to lock the containers to it.
  • the tensioner wheels are symmetrically arranged at each side of the drive wheel.
  • each of the tensioner wheels is hinged to a shaft, which is tensioned by a spring force, and preferably said spring force is dimensioned to ensure sufficient tightening of the chain.
  • said spring force or said tensioner wheels are coupled to an activation mechanism which activates one or the other of the tensioner wheels in dependence of whether the chain is driven in one or the other direction.
  • the chain runs along the entire length of the grabber arm and over a turning wheel placed at each opposite end of said arm.
  • the grabber arm is effectively embedded by or surrounded by the chain.
  • a container can be moved both by a movement of the chain alone or by a movement of the grabbing arm alone, or by a simultaneous movement of both the chain and the grabbing arm.
  • the container is moved by a movement of the chain alone, followed by a movement of the grabbing arm alone or vise versa, depending on whether the container is transferred to or from the vehicle.
  • the transfer system according to the invention may further comprise wheel locking means for locking the turning wheels and thereby causing the grabber arm to move when the endless chain is driven.
  • the wheel locking means are activated to lock the turning wheels when the grabber arm is moved from the vehicle into the opening in the frame placed under the freight container until the grabber arm reaches a position wherein the grabber arm engages the frame of the container, after which the wheel locking means are released and the container is pulled onto the vehicle by driving the chain in the opposite direction.
  • At least one catch is fixed to the chain, said catch comprising a transversal shaft for engaging a feature of the frame under the container.
  • Preferably, only one catch is attached to the chain.
  • the catch is fixed to one single chain link, such that the transversal shaft may follow the turning wheels to a position lower than the upper side of the grabbing arm, and be inserted into an opening of the frame, where after it may be locked to said frame by a movement of the chain in the opposite direction.
  • each of the grabbing arms is placed on an elongated console having a first and a second end and substantially the same length as the grabbing arm, said console comprising identical activation means placed at each end thereof, each said activation means being operatively connected to at least one container lock for fixing a container to the vehicle by locking engagement to the container frame when the grabbing arm slides past said activation means.
  • said container locks engage the inner side of the frame of the container when the container is locked to the vehicle.
  • the grabbing arm is operable to be moved in a direction away from the railway freight car, to or from which freight car a container is to be moved in order to first deactivate the container lock(s) in the side of the vehicle that are furthest away from the railway freight car.
  • the grabbing arm is operable to be moved in a direction towards the railway freight car, to or from which freight car a container is to be moved in order to secondly deactivate the container lock(s) in the side of the vehicle that are closest to the railway freight car.
  • the transfer system according to the invention may further comprise grabbing arm locking means which are operable to fix the grabbing arm relative to the vehicle when the wheel locking means are released in order to ensure that there is no movement of the grabbing arm when only the chain is to be moved; otherwise the arm will move as well due to inevitable friction.
  • the transfer system according to the invention may in a further embodiment comprise at least one locking arm configured for engaging a special lock in the railway freight car in order to unlock the frame and thereby the container that is placed on the railway freight car.
  • said locking arm furthermore causes alignment of the vehicle with the particular railway freight car, to or from which the container is to be moved.
