Description
- This invention provides a system for transporting and unloading containers for goods, in particular for bulk material, comprising a container suited to a container spreader with a system of rotatable locking pins for catching the container, comprising a bottom, side walls, a rear wall and a front wall in a form of a hatch pivotable about its upper edge, comprising a mechanism to lock the hatch and a catching assembly with a catch for locking the hatch in a closed position, and comprising a container spreader with a system of rotatable locking pins actuated by means of actuators, for catching the container, as well as a container and a container spreader included in the system.
- Varied systems for transporting and unloading containers are known in the art.
- Innofreight system from SKARNA SP. Z 0.0 company is known. In this system, containers, open or openable at the top, are shipped and unloaded by means of a fork lift carriage by turning them upside down which causes the load being poured out under the wheels of the carriage. Upon unloading of the container it is necessary to move the load into a storage location. In this system heavy containers exert a high pressure onto the wheels of the fork lift carriage and this requires high durability of the pavement of the unloading site. This system uses containers of a small capacity which affects efficiency of transportation thereof.
- Also known are systems that comprise a container spreader with a system of rotatably locking pins ("twist-locks") and containers intended for such a spreader.
- Most commonly, a container spreader is a part of a reach-stacker vehicle and is fastened on an extension arm of such a vehicle. For example, such system is offered by LAUDE SMART INTERMODAL S.A. Usually in such system a container has a bottom, side walls, a rear wall and a front wall in a form of a double door, most frequently the container also being closed at the top. In this system a spreader is affixed on an extension arm of the vehicle so as its long axis is perpendicular to the longitudinal axis of the vehicle. Unloading of the container is effected by tilting the container about its short axis, i.e. perpendicularly to the longitudinal axis of the vehicle. In order to unload the container, its door is manually open by an operator in close vicinity of the vehicle which poses a risk of the operator contacting the container or the vehicle. Moreover, pouring out of goods is in this system is hindered due to the fact that the container may be titled at a small angle only and also because the container doors are narrower than the container width. In this systems small containers are used that have walls made of corrugated plate. Small capacity of the containers affects efficiency of transport and the corrugated plate used in their construction also hinders pouring out of goods.

In an embodiment not shown thecontainer 1 may be provided with a running gear, being bogies, in particular these may be bogies of a railway type. - In
fig. 4 alocking mechanism 8 for locking ahatch 6 of acontainer 1 is positioned along a vertical edge of aside wall 4 of thecontainer 1 at the side of thehatch 6 and it comprises atie rod 9 the upper end of which is connected to abutton 12 for activating thelocking mechanism 8. In the embodiment offig. 4 , alever 10 is secured to the lower end of thetie rod 9, the opposite end of thelever 10 being connected to a catchingassembly 7 for locking thehatch 6 of thecontainer 1 in a closed position. In this embodiment thelever 10 of thelocking mechanism 8, at the site where it is connected to thetie rod 9, abuts a lower edge of a wall of thecontainer 1, by means of aspring 13 and securingelements 18. The catchingassembly 7 comprises atransverse bar 19 extending along the lower edge of thehatch 6, provided withcatches 7a, and furthermore thetie rod 9 is provided with agrip 20. - A
container spreader 2, suited to thislocking mechanism 8 and not shown in the drawing, has oneopening actuator 15 for opening thehatch 6 of the container, cooperating with themechanism 8 for locking the hatch 6 (as shown infig. 4 ) positioned along a vertical edge of oneside wall 4 of thecontainer 1 at the side of thehatch 6, upon connection of thecontainer 1 to thecontainer spreader 2 by means of rotatable locking pins 14. - In another embodiment of a container, a
locking mechanism 8 for locking thehatch 6 of thecontainer 1 may be positioned at the front edges of bothside walls 4 of thecontainer 1 at the side of thehatch 6. In such embodiment, acontainer spreader 2 suited to thecontainer 1 has two openingactuators 15 positioned respectively in a manner so as to cooperate with thecorresponding locking mechanisms 8 for locking thehatch 6 positioned along the vertical edges of bothside walls 4 of thecontainer 1 at the side of thehatch 6. - It will be obvious for a person skilled in the art that a
container 8 may have both its front side and its rear side in a form of ahatch 6 at the same time, and they may be handled by twoseparate locking mechanisms 8, positioned at the front and at the back of the container, each at thecorresponding hatch 6, or they may be handled by one sharedlocking mechanism 8. - In the embodiment shown in
fig. 5 acontainer spreader 2 has two openingactuators 15 for openinghatches 6 ofcontainers 1 of different sizes. Each ofsuch actuators 15 cooperates with alocking mechanism 8 for locking thehatch 6 in acontainer 1 of a different size. The openingactuators 15 cooperate with lockingmechanisms 8 for locking thehatch 6 upon connecting thecontainer 1 to thecontainer spreader 2 by means of rotatable locking pins 14. Avalve 16 is provided for switching between these actuators 15. -
Actuators 15 may be actuators of any suitable type, and in particular they may be hydraulic actuators. - It is clear that the invention is not limited to the embodiments shown and diverse modifications/combinations thereof are possible within the scope of the patent claims.
