- US2003152447 discloses an automated refuse container loader that is mounted to the side of a truck and adapted for lifting refuse containers and emptying them into a hopper.
- the loader is equipped with a lift arm that has a gripping element with gripping jaws for engaging refuse containers attached to it.

- EP 0 078 011 A1 discloses in Fig. 5 , 6 a lifting and loading device for side loading refuse collection trucks, the lifting and loading mechanism of which has a movable beam and gripping unit for engaging and lifting refuse containers, a locking device for locking refuse containers to the gripping unit, whereby the beam is positioned between the driver's compartment and the body of a refuse collection truck, whereby the gripping unit has locking device enabling locking of the refuse container on both sides of the refuse collection truck, whereby the said gripping unit is pivotable a- round an axis and attached to the beam, whereby the beam is pivotable around a (further) axis to both sides of the refuse collection truck, so that the gripping unit is adapted to grip and lock to the refuse container on both sides of the refuse collection truck.
- the lifting and loading devices of side loading refuse collection trucks known from the state of the art have some weak points.
- the distance between the vehicle and the refuse container to be emptied must be greater than that required by the lifting device of the invention, which gives the solution of this device the advantage of the refuse collection truck using less street space for loading refuse, since the lifting device lifts refuse containers from a shorter distance in relation to the body of the refuse collection truck than in the case of known solutions (especially compared to NTM OM side loaders).
- the design of some side loading lifting devices is such that they use claws or jaws to grasp around refuse containers. The shortcoming of this design is that there must be gaps between refuse containers or they cannot be too close to any obstacles (poles, cars, mailboxes, etc.), since the containers cannot be grappled in such cases.
- the lifting and loading devices of the state of art do not allow loading of refuse containers from both sides of a refuse collection truck.
- the aim of the invention is to overcome the aforesaid drawbacks of the known prior art. This is achieved by means of a refuse collection truck having the features of claim 1.
- a cantilevered lifting and loading device for refuse collection trucks is located in the middle of the vehicle behind the driver's compartment, which ensures the kinematics of a lifting mechanism that is analogous to the lifting mechanism of a rear-loading refuse collection truck. This enables lifting containers quite close to the side of the refuse collection truck, meaning that less lifting space is needed on the street.
- the device of the invention also comprises a horizontal linear movement mechanism to engage and lift refuse containers, enabling the device to grapple a container from a distance so that the refuse collectors do not have to manually push containers next to the truck.
- the loading of refuse containers can be controlled from the driver's compartment.
- the lifting and loading device of refuse containers includes a cantilevered lifting mechanism that is movable towards the side of the truck on rollers, slide surfaces or similar implements.
- the mechanism comprises a beam, which has a gripping unit for gripping refuse containers, and the beam and gripping unit are pivotable in relation to the attachment axis, and their tilt angles are controlled manually or electronically, by a computer processor.
- the coordination of the base with horizontal linear movement, the beam, the gripping unit and the hydraulic cylinders for the latching of refuse containers ensures control and navigation of the position of refuse containers, which is especially important in the given solution since the lifting and loading device is adapted for operation on both sides of refuse collection trucks.
- a flexible support is provided in order to limit the motion range of refuse containers in the phase of emptying them as well as to facilitate discharge.
- a double door covering the refuse hatch which opens in two directions and is located in the upper part of the body of a refuse collection truck, may be used.
- the lifting and loading device of refuse containers with a cantilevered design comprises a beam 1 (figure FIG 1 ), which is attached to the front of the body of a refuse collection truck 2 behind the driver's compartment 3 (shown in FIG 2 ), which enables lifting a refuse container 4 maximally close to the refuse collection truck since less space is needed to lift containers and empty them into the refuse collection truck.
- the beam 1 of the lifting device is equipped with a drive 5, e.g. hydraulic or electric motor, which transfers torque to the gripping unit 7 of containers by way of a cogwheel 6. Chain or other similar transmissions may be used instead of the gear transmission.
- the position of the refuse container 4 can simultaneously be adjusted and finally emptied into the refuse collection truck 2.
- the beam 1 rotates around the axis 9, and the gripping unit 7 similarly rotates around its axis 10.
- a hydraulic or electric motor is used to rotate the gripping unit 7, the trajectory of the refuse container 4 can be changed if needed, and it is mechanically not dependent on the angle of rotation of the beam 1 as is the case when the comb lifters of traditional refuse collection trucks (rear and side loaders) are used.
- This also enables separately controlling the angle of the gripping unit 7 by the use of an electronic computer processor (not shown in the figure) or manually, irrespective of the position of the beam 1.
- the means for locking refuse containers 4 to the gripping unit 7 is shown in FIGS 4A, 4B , 4C .
- the locking means is similar to the locking mechanism of comb lifters known from the state of art.
- the locking means comprises a locking device 11 pivotably connected to the gripping unit 7, which essentially includes a plate the width of which corresponds to the gripping unit.
- the free edge is movable by the use of the cylinder of the locking device 12 and can be fixed to both sides of the gripping unit 7.
- both ends of the locking device have a cylinder 12. This ensures that the edge of a refuse container can securely be fixed between the gripping unit and locking device.
- the locking device works in both cases: when refuse containers are engaged from either the right or left side of refuse collection trucks.
- FIG 4A shows a situation in which the locking mechanism of the refuse container 4 is opened when the refuse container is engaged and locked from the right side of the refuse collection truck.
- FIG 4B shows a situation in which the locking mechanism of the refuse container 4 is opened when the refuse container is engaged and locked from the left side of the refuse collection truck.
- FIG 4C shows a situation in which the locking mechanism of the refuse container 4 is closed.
- the dashed line indicates the extreme positions of the locking mechanism in the opened positions.
- the locking device 11 ensures that the gripping unit 7 is fixed against the container 4 so that the refuse container 4 would not be disengaged from the gripping unit 7 when the container is lifted and emptied into the refuse collection truck 2.
- a flexible support 13 is provided to limit the motion range of the refuse container 4 in the phase of emptying it as well as to facilitate discharge.
- a double door equipped with a spring and covering the refuse hatch which opens in two directions and is located in the upper part of the body of refuse collection trucks, may be used (not shown in the figures).
- the horizontal linear movement of the gripping unit In order to engage the container further away from the refuse collection truck, the horizontal linear movement of the gripping unit must be enabled. To achieve this, the entire lifting device is attached to the moving frame 14 (see FIG 3 ), which is moved by means of a hydraulic cylinder 15 or other drive.
- the frame may be equipped with rollers or slide surfaces that facilitate horizontal movement along guide rails 16.
- the dotted line in FIG 5 indicates how a refuse container is engaged if the container is in position I. II, III and IV mark the different stages of lifting and loading a refuse container.

- One of the novelties of the lifting device is that it can be used to engage containers from both sides of refuse collection trucks (the position indicated with a dotted line in FIG 1 ).
- the gripping unit 7 and locking device 11 have a partially symmetrical design for this purpose, which makes it possible to engage and lock containers from both sides of a refuse collection truck. This ensures that refuse containers can be emptied from both sides of a refuse collection truck, like figures FIG 5 and FIG 6 schematically show.
- the hydraulic cylinder 8 works as a crank mechanism (see FIG 7 ), making it possible for the lifting device to move over the central axis using the force of inertia.
- other drives may also be used instead of the hydraulic cylinder 8 to lift the beam 1, such as a hydraulic or electric motor 17 with gear transmission 18 or a drive with other types of transmission.
- the gear transmission 18 is fixed to the beam and ensures its rotational motion.
- the operating cycle of the lifting device of the invention is depicted in FIG 5 .
- the phases of the operating cycle are as follows: I - engagement and pulling of the refuse container, II - simultaneous lifting and opening of the lid, III - stopping the refuse container against the limiter, IV - emptying of the refuse container into the refuse collection truck.

EP 0 078 011 A1 discloses inFig. 5 ,6 a lifting and loading device for side loading refuse collection trucks, the lifting and loading mechanism of which has a movable beam and gripping unit for engaging and lifting refuse containers, a locking device for locking refuse containers to the gripping unit, whereby the beam is positioned between the driver's compartment and the body of a refuse collection truck, whereby the gripping unit has locking device enabling locking of the refuse container on both sides of the refuse collection truck, whereby the said gripping unit is pivotable a- round an axis and attached to the beam, whereby the beam is pivotable around a (further) axis to both sides of the refuse collection truck, so that the gripping unit is adapted to grip and lock to the refuse container on both sides of the refuse collection truck. - The companies Scania and Faun offer side loading refuse collection vehicles that are equipped with a movable beam and gripping unit behind the driver's compartment, which can be moved up and down as well as towards the side on a moving base, thus providing better manoeuvrability for emptying refuse containers. It is not possible to load refuse containers from both sides of the vehicle.
- The lifting and loading devices of side loading refuse collection trucks known from the state of the art have some weak points. For example, the distance between the vehicle and the refuse container to be emptied must be greater than that required by the lifting device of the invention, which gives the solution of this device the advantage of the refuse collection truck using less street space for loading refuse, since the lifting device lifts refuse containers from a shorter distance in relation to the body of the refuse collection truck than in the case of known solutions (especially compared to NTM OM side loaders). The design of some side loading lifting devices is such that they use claws or jaws to grasp around refuse containers.

The lifting and loading devices of the state of art do not allow loading of refuse containers from both sides of a refuse collection truck.
- The aim of the invention is to overcome the aforesaid drawbacks of the known prior art. This is achieved by means of a refuse collection truck having the features of
claim 1. In a truck according to the invention, a cantilevered lifting and loading device for refuse collection trucks is located in the middle of the vehicle behind the driver's compartment, which ensures the kinematics of a lifting mechanism that is analogous to the lifting mechanism of a rear-loading refuse collection truck. This enables lifting containers quite close to the side of the refuse collection truck, meaning that less lifting space is needed on the street. The device of the invention also comprises a horizontal linear movement mechanism to engage and lift refuse containers, enabling the device to grapple a container from a distance so that the refuse collectors do not have to manually push containers next to the truck. The loading of refuse containers can be controlled from the driver's compartment. The lifting and loading device of refuse containers includes a cantilevered lifting mechanism that is movable towards the side of the truck on rollers, slide surfaces or similar implements. The mechanism comprises a beam, which has a gripping unit for gripping refuse containers, and the beam and gripping unit are pivotable in relation to the attachment axis, and their tilt angles are controlled manually or electronically, by a computer processor. The coordination of the base with horizontal linear movement, the beam, the gripping unit and the hydraulic cylinders for the latching of refuse containers ensures control and navigation of the position of refuse containers, which is especially important in the given solution since the lifting and loading device is adapted for operation on both sides of refuse collection trucks. A flexible support is provided in order to limit the motion range of refuse containers in the phase of emptying them as well as to facilitate discharge. In an alternative embodiment, a double door covering the refuse hatch, which opens in two directions and is located in the upper part of the body of a refuse collection truck, may be used. - A more detailed overview of the invention is provided by reading the following detailed description of an exemplary embodiment in conjunction with the attached figures, wherein:
-
FIG 1 is a front view of the cantilevered lifting and loading device for refuse containers of the invention; -
FIG 2 is a top view of the cantilevered lifting and loading device for refuse containers of the invention; -
FIG 3 shows the movable frame of the cantilevered lifting and loading device of refuse containers of the invention, which is used to move refuse containers horizontally; -
FIGS 4A, 4B ,4C show the different positions of the locking device in the detailed view B of figureFIG 3 ; -
FIG 5 shows the operating cycles of the lifting and loading device of the invention and the movement trajectory of a refuse container when the container is located on the right side of the truck; - Figure
FIG 6 shows the operating cycles of the lifting and loading device of the invention and the movement trajectory of a refuse container when the container is located on the left side of the truck. - Figure
FIG 7 shows the position of the beam of the lifting and loading device of the invention during a transition from right side loading to left side loading. - Figure
FIG 8 shows an alternative drive for the beam of the lifting and loading device of the invention, which is a hydraulic or electric motor with transmission. - The lifting and loading device of refuse containers with a cantilevered design comprises a beam 1 (figure
FIG 1 ), which is attached to the front of the body of arefuse collection truck 2 behind the driver's compartment 3 (shown inFIG 2 ), which enables lifting arefuse container 4 maximally close to the refuse collection truck since less space is needed to lift containers and empty them into the refuse collection truck. In order to ensure the optimum trajectory when arefuse container 4 is lifted and emptied, thebeam 1 of the lifting device is equipped with adrive 5, e.g. hydraulic or electric motor, which transfers torque to thegripping unit 7 of containers by way of acogwheel 6. Chain or other similar transmissions may be used instead of the gear transmission. When thebeam 1 is lifted using ahydraulic cylinder 8, the position of therefuse container 4 can simultaneously be adjusted and finally emptied into therefuse collection truck 2. When lifted, thebeam 1 rotates around theaxis 9, and thegripping unit 7 similarly rotates around itsaxis 10. When a hydraulic or electric motor is used to rotate thegripping unit 7, the trajectory of therefuse container 4 can be changed if needed, and it is mechanically not dependent on the angle of rotation of thebeam 1 as is the case when the comb lifters of traditional refuse collection trucks (rear and side loaders) are used. This also enables separately controlling the angle of thegripping unit 7 by the use of an electronic computer processor (not shown in the figure) or manually, irrespective of the position of thebeam 1. This solution of rotational movement of the gripping unit makes it possible to engage thecontainer 4 from both sides of refuse collection trucks since the reach of the rotational movement of the gripping unit is not limited. If a hydraulic or electric motor with sufficiently high torque can be used, gear or other types of transmission may turn out to be unnecessary to rotate thegripping unit 7, and the drive (motor) may directly be connected to thegripping unit 7. - The means for locking
refuse containers 4 to thegripping unit 7 is shown inFIGS 4A, 4B ,4C . In its essence, the locking means is similar to the locking mechanism of comb lifters known from the state of art. The locking means comprises alocking device 11 pivotably connected to thegripping unit 7, which essentially includes a plate the width of which corresponds to the gripping unit. The free edge is movable by the use of the cylinder of thelocking device 12 and can be fixed to both sides of thegripping unit 7. In the preferred embodiment, both ends of the locking device have acylinder 12. This ensures that the edge of a refuse container can securely be fixed between the gripping unit and locking device. The locking device works in both cases: when refuse containers are engaged from either the right or left side of refuse collection trucks.FIG 4A shows a situation in which the locking mechanism of therefuse container 4 is opened when the refuse container is engaged and locked from the right side of the refuse collection truck.FIG 4B shows a situation in which the locking mechanism of therefuse container 4 is opened when the refuse container is engaged and locked from the left side of the refuse collection truck.FIG 4C shows a situation in which the locking mechanism of therefuse container 4 is closed. The dashed line indicates the extreme positions of the locking mechanism in the opened positions. The lockingdevice 11 ensures that thegripping unit 7 is fixed against thecontainer 4 so that therefuse container 4 would not be disengaged from thegripping unit 7 when the container is lifted and emptied into therefuse collection truck 2. Aflexible support 13 is provided to limit the motion range of therefuse container 4 in the phase of emptying it as well as to facilitate discharge. In an alternative embodiment, a double door equipped with a spring and covering the refuse hatch, which opens in two directions and is located in the upper part of the body of refuse collection trucks, may be used (not shown in the figures). - In order to engage the container further away from the refuse collection truck, the horizontal linear movement of the gripping unit must be enabled. To achieve this, the entire lifting device is attached to the moving frame 14 (see
FIG 3 ), which is moved by means of ahydraulic cylinder 15 or other drive. The frame may be equipped with rollers or slide surfaces that facilitate horizontal movement along guide rails 16. The dotted line inFIG 5 indicates how a refuse container is engaged if the container is in position I. II, III and IV mark the different stages of lifting and loading a refuse container. A computer processor controlling the movement of the lifting and loading device is configured to change the tilt angle of the gripping unit in these different stages as well as the tilt angle of the refuse container locked to the gripping unit with the lockingdevice 11, taking the height of the refuse container and the position of the movingframe 14 into account. - One of the novelties of the lifting device is that it can be used to engage containers from both sides of refuse collection trucks (the position indicated with a dotted line in
FIG 1 ). Thegripping unit 7 and lockingdevice 11 have a partially symmetrical design for this purpose, which makes it possible to engage and lock containers from both sides of a refuse collection truck. This ensures that refuse containers can be emptied from both sides of a refuse collection truck, like figuresFIG 5 andFIG 6 schematically show. - In order to guide the lifting device to one side of a refuse collection truck or the other, the
hydraulic cylinder 8 works as a crank mechanism (seeFIG 7 ), making it possible for the lifting device to move over the central axis using the force of inertia. As shown schematically inFIG 8 , other drives may also be used instead of thehydraulic cylinder 8 to lift thebeam 1, such as a hydraulic orelectric motor 17 withgear transmission 18 or a drive with other types of transmission. Thegear transmission 18 is fixed to the beam and ensures its rotational motion. - The operating cycle of the lifting device of the invention is depicted in
FIG 5 . The phases of the operating cycle are as follows: I - engagement and pulling of the refuse container, II - simultaneous lifting and opening of the lid, III - stopping the refuse container against the limiter, IV - emptying of the refuse container into the refuse collection truck.
