Definitions

• the present invention relates to a device for a yoke which may be tipped and which is provided with a load function and which may be detachable connected to the forks of a lift truck or another vehicle which is provided with forks.
• the wheel equipped vessels are easy to empty with a special equipped refuse collection vehicle, like in residential districts.
• this handling is experienced as circumstantial when the vessels must be rolled or be transported to a centrally located larger container within a factory or an industrial area.
• a full size container which only shall contain waste paper and not corrugated cardboard must have a much larger area of collecting than a collection container for unsorted waste .
• Fork-lift trucks may not today handle the wheel equipped vessels, but must have truck adapted metal containers. These containers are not adapted for sorting at the source, and are considered as difficult to handle at the locations of collecting closest to the individual working sites.
• the truck vehicle may be equipped with all sorts of special equipment for side displacement of the lifting equipment. But the truck vehicle then will have a completely different and more demanding work pattern than what is given priority to during design and driver education.
• the equipment requires that the driver leaves his driver's seat and performs a coupling of the equipment and the truck vehicle, in view of power supply and control linkage.
• the main object of the present invention is therefore primarily to try to solve the problem with simple and still well functioning means for combining the advantages of in itself previously known systems and thereby enabling rational fork-lift truck handling of wheel equipped container vessels of primarily plastic material.
• a device which is substantially characterized in that the yoke is provided with a driving motor and generators of lifting force which are separate from said vehicle, and that the yoke has such a centre of gravity that it stays within the ordinary lift forks of the vehicle both in empty as well as in filled condition.
• fork-lift trucks or other fork equipped work vehicles may fetch and use the device according to the invention for complete handling of it without any need for the driver to leave the designated normal driver's seat for this purpose.
• Fig 1 and 2 shows device in function for different tipping of vessels and containers.
• a device 1 for a yoke 2 which may be tipped and which is provided with a load function, and which may be detachable connected to the ordinary forks 3 of a truck vehicle 4 or any other transportable vehicle which is provided with fork-lift, has the yoke 2 arranged so that it is provided with its own motor 5, which is individual of the vehicle 4. Also, the yoke 2 is provided with generators 6 , 7 of lifting force and that it has such a centre of gravity that it stays within the ordinary lift forks 3 of the vehicle both in empty as well as in filled condition.
• the yoke 2 is arranged thanks to its independent power supply and function as emptying equipment for lifting and moving vessels 8 which are provided with handles to be tipped into intended container 9 of the yoke 2 in question.
• a smaller collecting container which contains the contents from a number of even smaller vessels 8 provided with wheels 10, may thus be received to be carried by the yoke 2 and form said collecting container 9.
• the mentioned with the yoke 2 connected collecting container 9 is provided with handling and lifting means 11 at the end which is facing away from the vehicle 4, in order to lift and empty receiving vessels 8 into the collecting container 9 after gripping.
• the yoke 2 is provided with its completely independent power supply by rechargeable battery connection 5 and that the drive means of the yoke and the control means 6 , 7 are arranged to be controlled via wireless remote control without external connection to the referred vehicle 4.
• the vehicle 4 preferably consists of a transportable lift truck which with the yoke 2 as a facility maintains the normal work function of the vehicle by driving along the normal route for lifting 12 and sinking 13 respectively of the lift forks 3.
• the lift yoke 2 is provided with a pivot bearing 14 at that end A which is distal from the vehicle coupling side, for the referred collecting container 9.
• the mentioned pivot bearing 14 is located on an upright 15 in a raised position with reference to the lift forks 3 and the connection member 16 of the vehicle for the yoke 2 for this.
• the own separate preferably remotely controlled lift function means of the yoke are performance locked via pressure limiters in lift jacks 6, 7, preferably hydraulic operating cylinder pistons, so that overloading is avoided and/or cautioned against.
• the yoke 2 is provided with means 16 with insert function for connection with the forks 3 in the direction from its front so that the driver of the lift truck 4 may manoeuvre the yoke 2 from the driver's seat 17 for all goods handling when the yoke 2 is used for lifting and moving vessels 8 which are provided with handles and wheels for emptying into the collecting container 9 which may be carried by the yoke for subsequent emptying out of it by tipping into a larger collecting container 18 intended to be transported away by car.
• the collecting container 9 may be tipped for emptying at optional height by exploiting the lifting function of the fork-lift truck 4 for reaching the height, and the tipping function of the equipment in order to empty it into a larger central container 18 or cargo truck container.
• the tipping function is operated via remote control without that the driver need to leave the truck 4.
• the emptying function for e.g. plastic vessel 8 may be used without the driver having to leave the truck 4.
• the truck, with the equipment on the forks 3 is driven towards the vessel 8 which shall be emptied.
• the driver remotely controls the vessel emptying function of the equipment and drives on to the next vessel when the vessel has been returned to its original position.
• the truck 4 for example drives out to the central large container and tips into it.
