Description

WO 2016/124598 1 PCT/EP2016/052184
A sideloader as well as a lifting device suitable for such a sideloader FIELD OF THE INVENTION
The invention relates to a sideloader comprising a chassis and at least two spaced-apart lifting devices for moving a load present in a first position between the lifting devices on the chassis to a second position beside a first side of the chassis and to a third position beside a second side of the chassis spaced from the first side, and vice versa, wherein at least one lifting device comprises a frame, a first pivot arm and a second pivot arm, which first pivot arm is pivotally connected to the frame about a first pivot shaft near a first end and which is pivotally connected to the second pivot arm about a second pivot shaft near a second end remote from the first end, which first pivot shaft is located near the first side of the chassis.
The invention further relates to a lifting device suitable for such a sideloader.
BACKGROUND OF THE INVENTION
Such a sideloader is known, for example from German patent DE19516357A1. Such sideloaders are for example used for placing loads such as skips or containers onto a chassis. The chassis is preferably mobile and can be coupled to a truck or form part of a truck. At the desired location, the load is subsequently moved from the chassis to a position beside the chassis. Using the sideloader according to German patent DE19516357A1, it is possible to place the load on either side of the chassis.
The lifting device used in the sideloader known from German patent DE19516357A1 comprises a girder that is pivotally connected to the frame about a first pivot shaft, a lower jib that is pivotally connected to the girder about a second pivot shaft and an upper jib that is pivotally WO 2016/124598 2 PCT/EP2016/052184 connected to the lower jib about a third pivot shaft. The first pivot shaft is located near a first side of the chassis. Pivoting about the pivot shafts takes place by means of hydraulic cylinders. The upper jib is provided with means that can be detachably connected to the load. 5 When a load is picked up from and placed onto the second position beside the first side of the chassis, the girder is pivoted through a relatively large angle about the first pivot shaft from a substantially horizontally extending position to a substantially vertically extending position or to a position in which it extends above the second position. The lower jib can 10 pivot about the second pivot shaft during said movement.
When a load is picked up from and placed onto the third position beside the second side of the chassis, the girder is supported on a support portion with an end remote from the first pivot shaft. The lower jib can pivot about the second pivot shaft in the situation in which the girder is 15 supported on the support portion.
Upon pivoting of the lower jib about the second pivot shaft whilst the girder is supported on the support portion, the girder and the first pivot shaft are subjected to relatively large torques about a virtual torque shaft extending between the first and the second pivot shaft. This makes it 20 necessary to design the first pivot shaft and the girder to be relatively strong and thus heavy.
DESCRIPTION OF THE INVENTION 25 The object of the invention is, inter alia, to provide a sideloader by means of which the forces exerted on the first pivot arm are reduced, at least upon picking up or placing a load from/onto the third position beside the second side of the chassis, and/or undesirable deformation of the first pivot arm is prevented. WO 2016/124598 3 PCT/EP2016/052184
This object is achieved with the sideloader according to the invention in that the lifting device is provided with locking means for locking the first pivot arm to the frame in a locked position near the second end, in which locked position the second pivot arm is pivotable about the 5 second pivot shaft for moving the load from or to the third position, whilst torsional forces on the first pivot shaft and the first pivot arm about a virtual torque shaft extending between the first and the second pivot shaft are prevented.
By locking the first pivot arm to the frame, the forces exerted on 10 the first pivot arm by the second pivot arm upon picking up or placing a load from/onto the third position beside the second side of the chassis are transmitted to the frame by the locking means located near the second end of the first pivot shaft, as a result of which torsional forces on the first pivot shaft and the first pivot arm are prevented. 15 Said locking of the first pivot arm for example takes place as soon as the end of the second pivot arm remote from the first pivot arm is moved to a side of a virtual vertical plane that faces away from the first pivot shaft, which plane extends parallel to the pivot shafts, through the centre of the sideloader. 20 If desired, said locking of the first pivot arm can only take place if the forces exerted on the first arm are expected to be relatively large. If, for example, the movement of the pivot arms is carried out without a load being moved by the lifting device, the movement to the third position can take place without the first pivot arm being locked. 25 When a load is to be picked up or placed from/onto the second position beside the first side of the chassis, the locking means are unlocked, so that the first pivot arm can be freely pivoted about the first pivot shaft.
One embodiment of the sideloader according to the invention is characterised in that the locking means comprise a movable element which 30 is movable from an unlocked position, in which the movable element is WO 2016/124598 4 PCT/EP2016/052184 located in the first pivot arm or in the frame, to a locked position, in which the movable element is located in the first pivot arm and the frame.
Locking is effected in a simple manner in that the movable element is located in the first pivot arm as well as in the frame in the locked 5 position and only in either the first pivot arm or the frame in the unlocked position. The movable element can be moved in a translational movement and/or a rotary movement. If the movable element is located in the first pivot arm, the frame is preferably provided with a passage into which the movable element can be positioned to fit therein by said movement. If the 10 movable element is located in the frame, the passage will be located in the first pivot arm.
Another embodiment of the sideloader according to the invention is characterised in that the movable element comprises a pin which is slidably accommodated in the first pivot arm, which pin extends partially 15 into an opening present in the frame in the locked position.
Using such a pin which is positioned in the opening in the frame, an adequate locking engagement of the first pivot arm with the frame is obtained in a simple manner.
The diameter of the pin depends on the forces exerted on the pin 20 by the second pivot arm.
Another embodiment of the sideloader according to the invention is characterised in that the pin extends parallel to the first and the second pivot shaft.
With such an orientation of the pin, shear forces are exerted on 25 the pin in a direction transversely to the longitudinal direction of the pin, in which direction the pin can effectively transmit such forces to the frame.
Another embodiment of the sideloader according to the invention is characterised in that the opening in the frame of the lifting device is located on a side of the first pivot arm of the lifting device remote from the 30 other lifting device. WO 2016/124598 5 PCT/EP2016/052184
In this way the side of the frame that faces the other lifting device and the load present between the lifting devices in use can be designed to be relatively simple and thus narrow. In this way the distance between the load to be lifted and the first pivot arm can remain relatively limited. As a 5 result of said limited distance, the torsional forces exerted by the second pivot arm will be limited as well. On a side of the first pivot arm remote from the other lifting device, the frame can be designed to be sufficiently strong for effectively taking up the forces exerted on the frame by the pin present in the opening in the frame. to Another embodiment of the sideloader according to the invention is characterised in that the frame is provided with a cylindrical support near the locking means, whilst the first pivot arm is provided with a cylindrical bearing surface near the second pivot shaft, which bearing surface can be positioned against the cylindrical support. 15 The central axis of the cylindrical support and the cylindrical bearing surface preferably extends parallel to the second pivot shaft. Because the cylindrical bearing surface engages around the cylindrical support, an adequate positioning of the first pivot arm to the frame can be obtained, so that the first pivot arm can be connected to the frame in a 20 precise manner by the locking means. Locking preferably takes place when the load is supported on the chassis, so that the mechanical load of the lifting device will be minimal. Forces exerted substantially in vertical direction on the cylindrical support are taken up by the cylindrical support.
Another embodiment of the sideloader according to the invention 25 is characterised in that the lifting device is provided with at least one support leg, which comprises at least one first leg portion which is movable in horizontal direction relative to the frame, as well as a second leg portion which can extend in vertical direction, which second leg portion is connected to a side of the first leg portion remote from the frame. WO 2016/124598 6 PCT/EP2016/052184
Such a support leg makes it possible, via a desired horizontal movement of the first support leg, to cause the second support leg to be supported on a surface at a desired distance from the chassis, so that tilting of the chassis upon movement of the load is prevented in a simple manner. 5 Another embodiment of the sideloader according to the invention is characterised in that the second leg portion can pivot from a downward direction to an upward direction, and vice versa, about a horizontal axis through the first leg portion.
In a downward direction, the second support leg can be supported 10 on a surface. In the upward direction, the second support leg can be simply stowed away in the lifting device in the position in which the first support leg is practically entirely retracted in the frame, so that a compact lifting device is obtained, for example during transport of the lifting device. In addition, space is available above the first support legs and between the 15 second upwardly extending support legs for additional components of the sideloader, such as valve blocks, electric motors, a hydraulic tank, for example.
Another embodiment of the sideloader according to the invention is characterised in that the lifting device is provided with a first such 20 support leg on the first side and with a second such support leg on the second side, wherein the first leg portion of the first support leg is located above the first leg portion of the second support leg.
Because of the arrangement one above the other of the first support legs, a compact structure of the lifting device is obtained. 25 The first leg portion of the first support leg is spaced from a surface by a larger distance than the first leg portion of the second support leg. As a result, the first support leg can be easily positioned on the far side of a trailer present beside the chassis the lifting devices, for example, for subsequently transferring the load from the chassis to a trailer, or vice versa. WO 2016/124598 7 PCT/EP2016/052184
If desired, also the first leg portion of the second support leg can be positioned on the far side of a trailer or other vehicle present beside the chassis, for example, for moving a load from the chassis to the trailer, or vice versa. 5 Another embodiment of the sideloader according to the invention is characterised in that the first and/or the second leg portion comprise(s) a number of segments which are movable relative to each other.
Because the segments are movable relative to each other, the leg portion can be adjusted for length in a simple manner, to Another embodiment of the sideloader according to the invention is characterised in that on a side remote from the second pivot shaft, the second pivot arm is provided with means that can be detachably connected to the load.
Using such means, the load can be detachably connected to the 15 lifting device in a simple manner. Such means may for example comprise chains, cables or twist locks.
Another embodiment of the sideloader according to the invention is characterised in that the second pivot arm is provided with a number of telescoping parts on a side remote from the second pivot shaft. 20 Said telescoping parts make it possible to extend the second pivot arm under load, so that the range of the second pivot arm is increased. Extending the second pivot arm by means of the telescoping parts takes place in a stationary position of the chassis while the load is being moved between the first, the second and/or third positions. 25 Usually said parts are telescoped together or collapsed when the chassis is being driven or transported, so that it will have a minimal length. An associated safety system that may be provided does not allow the chassis to be moved if the lifting devices are not in a fully retracted and collapsed transport position. 30 WO 2016/124598 8 PCT/EP2016/052184

Figures 1-8C show various views of a sideloader 1 according to the invention. WO 2016/124598 9 PCT/EP2016/052184
The sideloader l comprises a chassis 2 and at least two spaced-apart lifting devices 3 for moving a load, such as a container C, present in a first position (figure 7C) between the lifting devices 3 on the chassis 2 to a second position (figures 1, 6A, 8C) on a surface beside a first left-hand side L of the chassis 3 and to a third position (figures 2A, 3A, 6H) on a surface beside a second right-hand side R spaced from the left-hand side L of the chassis 2, and vice versa.
The container C may be an ISO container, for example, having a standard height of 8.6 feet (2.59 m) or a high-cube container having a standard height of 9.6 feet (2.9 m).
The chassis 2 is for example a mobile trailer.
The lifting device 3 comprises a frame 4, a first pivot arm 5 and a second pivot arm 6. The first pivot arm is pivotally connected to the frame 4 about a first pivot shaft 8 near a first and 7 and is pivotally connected to the second pivot arm 6 about a second pivot shaft 10 near a second end 9 remote from the first end 7. The first pivot shaft 8 is located near the first left-hand side L of the chassis 2. The spacing between the first and the second pivot shaft 8, 10 is at least 1 m, preferably at least 2 m, for example 2.4 m.
The first pivot arm 5 can be pivoted about the first pivot shaft 8 by means of a hydraulic cylinder 11. The second pivot arm 6 can be pivoted about the second pivot shaft 10 relative to the first pivot arm 5 by means of a hydraulic cylinder 12.
The second pivot arm 6 comprises a first arm portion 13 which is pivotally connected to the second pivot shaft 10 and which is rotatably connected to one end of the hydraulic cylinder 12 about a rotary shaft 14. The second pivot arm 6 comprises a second arm portion 15 which is accommodated in the first arm portion 13 for movement therein in the direction indicated by arrow Pi and in the opposite direction, so that the length of the second pivot arm 6 can be varied. Because the second arm WO 2016/124598 10 PCT/EP2016/052184 portion 15 is supported within the first arm portion 13, the second arm portion 15 can also be moved in the direction indicated by arrow Pi and in the opposite direction within the first arm portion 13 while a container C is being moved. The first and the second arm portion 13, 15 are tubular in 5 shape, with the tubular shape of the first and the second arm portion 13, 15 having a trapezoidal configuration on at least one side and a flat configuration on at least one side opposite the trapezoidal side.
On a side of the second arm portion remote from the first arm portion 13, the lifting device 3 is provided with a connecting piece 16, which 10 is pivotally connected to the second arm portion 15 about a pivot shaft 17. The connecting piece 16 is provided with means that can be detachably connected to the container C, for example cables 18, which are connected to the connecting piece 16 with one end 19 and to the container C, via means known per se such as hooks placed in openings in the container C, with 15 another end 20.
The lifting device 3 is further provided with a support leg 21 on the left-hand side L and with a support leg 22 on the right-hand side R.
The left-hand support leg 21 comprises a horizontally extending first leg portion 23, which is provided with a first horizontally extending segment 20 24 which is movable in the direction indicated by arrow P2 and in the opposite direction within a tubular section 25 that is connected to the frame 4-
The first leg portion 23 further comprises a second horizontally extending segment 26, which is movable in the direction indicated by arrow 25 P3 and in the opposite direction within the first segment 24.
The left-hand support leg 21 further comprises a second leg portion 27, which is pivotable in the direction indicated by arrow P4 and in the opposite direction about a horizontal central axis 28 through the first leg portion 23 from a downward direction to an upward direction, and vice 30 versa. WO 2016/124598 11 PCT/EP2016/052184
The second leg portion 27 comprises a first segment 29 which extends transversely to the central axis 28, a second segment 30 which is movable in the direction indicated by arrow P4 and in the opposite direction within the first segment 29, and a support foot 31. The support foot 31 is connected to the segment 30 on a side remote from the first segment 29.
The right-hand support leg 22 comprises a horizontally extending first leg portion 33 which is movable in the direction indicated by arrow P5 and in the opposite direction within a tubular section 34 that is connected to the frame 4.
The right-hand support leg 22 further comprises a second leg portion 35 which is identical to the second leg portion 27 of the left-hand support leg 21. The second support leg 35 is pivotable in the direction indicated by arrow P6 and in the opposite direction about a horizontal central axis 36 through the first leg portion 33 from a downward direction to an upward direction, and vice versa.
In figure 1, the second leg portions 27, 35 extend in a downward direction. In figure 4, the second leg portions 27, 35 extend in an upward direction.
The tubular section 25 is located above the tubular section 34, so that the first leg portion 23 of the left-hand support leg 21 is spaced further from a surface 37 than the first leg portion 33 of the right-hand support leg 22. Because of this, the second segment 30 of the second leg portion 27 of the left-hand support leg 21 must be extended further from the first segment 29 so as to ensure that the support leg 31 is supported on the surface 37.
Figures 2A-2C and 3A-3C show a front view, a perspective view and larger-scale detail views of the sideloader 1, in which the lifting device 3 is in a position for placing a container C onto the right-hand side R of the chassis 2.
As shown in figures 2B and 3B, the first pivot arm 5 comprises a cylindrically curved bearing surface 41 near the second end 9 thereof. The WO 2016/124598 12 PCT/EP2016/052184 frame 4 comprises a cylindrical support 42, the central axis 43 of which extends parallel to the first and the second pivot shaft 8, 10. In the locked position shown in figure 3B, the cylindrical bearing surface 41 of the first pivot arm 5 bears against the cylindrical support 42 of the frame 4.
As is shown most clearly in figures 2C and 3C, the first pivot arm 5 comprises a bush 44 connected to the pivot arm 5, within which a pin 45 is movable in the direction indicated by arrow P7 and in the opposite direction. The pin 45 has a diameter of, for example, 30-100 mm. In the position of the first pivot arm 5 that is shown in figures 2C and 3C, the frame 4 is provided with an opening 46 coaxial with the pin 45 at the location of the pin 45,. The opening 46 in the frame 4 of the lifting device 3 is located on a side of the first pivot arm 5 remote from the other lifting device 3 and from the container C. A tubular part 47 connected to the frame 4 is coaxial with the opening 46.
Located within the bush 44 is a spring 48. The pin 45 is moved in the direction indicated by arrow P7 through the opening 46 in the tubular part 47 of the frame 4 under spring force of the spring 48. The pin 45 is in the closing position in that situation, in which the first pivot arm 5 is locked to the frame 4 in a locked position.
Using pneumatic or hydraulic pressure, the pin 45 can be moved in the opposite direction of arrow P7, out of the tubular part 47 and the opening 46, to an unlocked position entirely within the bush 44 against the spring force of the spring 48.
The pin 45 and the opening 46, together with the bush 44 and the tubular part 47, form locking means for locking the first pivot arm 5 to the frame 4 near the second end 9.
The pin 45 is positioned opposite the opening 46 in a simple manner by positioning the cylindrical bearing surface 41 of the first pivot arm 5 against the cylindrical support 42 of the frame 4 prior to moving the pin 45 to the closing position. WO 2016/124598 13 PCT/EP2016/052184
When loads, such as containers C, having a relatively large mass, for example of 20,000 to 50,000 kg, are being moved, the lifting device 3 is subjected to relatively large forces and moments.
When the first pivot arm 5 is in the locked position, torsion of the 5 first pivot arm 5 in the direction indicated by arrow P10 about a virtual torque shaft 55 extending between the first and the second pivot shaft 8, 10 upon pivoting of the second pivot arm 6 about the second pivot shaft 10 for placing or picking up a container C present beside the chassis 2 on the right-hand side of the chassis 2 in its entirety is prevented, and forces in 10 vertical direction on the second pivot shaft 10 are transmitted from the first pivot arm 5 to the frame 4 by the cylindrical bearing surface 41 that bears against the cylindrical support 42 of the frame 4, and torsional forces are taken up by the pin 45 present in the opening 46 of the frame 4.
Depending on the weight of the load and the dimension of the lifting 15 device, among other things, the pivoting angle and the length of the second pivot arm 6 can be determined, in which regard it is necessary to move the first pivot arm 5 to the locked position first before the second pivot arm 6 is further pivoted in the direction away from the first pivot arm 5 about the second pivot shaft 10. Preferably, the first pivot arm 5 is moved to the 20 locked position as soon as the pivot shaft 17 of the connecting piece 16 is moved to a side facing away from the first pivot shaft 8 of a virtual plane V (see figures 6D, 9) that extends vertically through the centre of the sideloader 1.
Figure 4 shows a rear view of the sideloader 1 in a collapsed transport 25 position.
Figure 5 shows a rear view of the sideloader 1 in a collapsed position of the pivot arms 5, 6 with extended support legs 21, 22.
Extending the segments 24, 25, 44 can for example be done by means of hydraulic or pneumatic cylinders. Rotating the second leg portions 27, 35, 30 which extend in upward direction in figure 4, about their central axes 28, 36 WO 2016/124598 14 PCT/EP2016/052184 to the downwardly extending position of the second leg portions 27, 35 can be done by means of a hydraulic, pneumatic or electric motor or by hand. Once the second leg portions 27, 35 extend in downward direction, the second leg portions 27, 35 are locked against rotation. 5 Using the sideloader 1 according to the invention it is possible to position the support foot 31 of the support leg 31 at a distance of 4.8 m from the centre of the chassis on the left-hand side L and to position the support foot 31 of the support leg 22 at a distance of 3.3 m from the centre of the chassis on the right-hand side R. 10 Figures 6A-6H are rear views of the sideloader 1 upon movement of a container C from the left-hand side L the right-hand side R.
Figure 6A shows the sideloader and a container C present on the surface 37 beside the sideloader 1. The second pivot arm 6 is now pivoted in the direction indicated by arrow P8 by extending the hydraulic cylinder 12. 15 At the same time, the second arm portion 15 is moved in the direction indicated by arrow Pi out of the first arm portion 13. The second pivot arm 5 is for that purpose provided with a hydraulic cylinder 49 (see figure 2A) which is pivotally connected to the first arm portion 13 about a pivot shaft 50 with a first end and to the second arm portion 15 (see figure 6B) with a 20 second end. The first pivot arm 5 is then pivoted in the direction indicated by arrow P9 (see figure 6C) by extending the hydraulic cylinder 11.
The movement of the second arm portion 15 in the direction indicated by arrow Pi and in the opposite direction, the pivoting of the first pivot arm 5 in the direction indicated by arrow P9 and in the opposite 25 direction and the pivoting of the second pivot arm 6 in the direction indicated by arrow P8 and in the opposite direction takes place by means of remotely or directly operable valve blocks as known per se, which may or may not be computer-controlled, via which valve blocks the various hydraulic and pneumatic cylinders are controlled, so that a desired 30 movement of the container C from the second position on the left-hand WO 2016/124598 15 PCT/EP2016/052184 side L, via an intermediate position above the chassis 2, to a third position on the right-hand side R can be carried out. The pivoting of the pivot arms 5, 6 and the extension of the second pivot arm 6 can take place simultaneously. Also the operation of the two lifting devices 3 can take 5 place simultaneously.
Figures 6D shows the sideloader 1 with the container C in the intermediate position above the chassis 2, in which position the distance to the chassis 2 is kept as small as possible so as to prevent unnecessary lifting of the container C. The second arm portion 15 has for that purpose been 10 moved in the direction indicated by arrow Pi into the first arm portion 13. In this situation the pivot shaft 17 of the connecting piece 16 is located in the virtual plane V that extends vertically through the centre of the sideloader 1. Before the second pivot arm 6 is further pivoted in the direction indicated by arrow P8, the first pivot arm 5 is first moved toward 15 the chassis 2 and locked to the frame 4 in the manner described above with reference to figures 2A-3C.
Figure 6E shows the sideloader 1 with the container C partially past the right-hand side of the frame 4 and the chassis 2. As shown in figure 6E, the first pivot arm 5 is locked to the frame 4. 20 Figure 6F is a view of the sideloader 1 with the container C in which the container C is spaced from the right-hand side of the frame 4 and the chassis 2 by a larger horizontal distance in comparison with the situation shown in figure 6E.
From the position shown in figure 6E, the second arm portion 15 is 25 moved in the opposite direction of arrow Pi. Because the second pivot arm 6 includes an angle H with the vertical, the container C will be moved in vertical direction toward the surface 37 as well as in horizontal direction toward the chassis 2 upon retraction of the second arm portion 15 until the container C has moved via the position shown in figure 6G to the position 30 beside the chassis 2 on the surface 37 as shown in figure 6H. WO 2016/124598 16 PCT/EP2016/052184
Figures 7A-7C show rear views of the sideloader 1 upon placement of a container onto the chassis 2.
In the position shown in figure 7A, the container C is positioned some distance above the chassis 2. By extending and retracting the second 5 arm portion 15 and pivoting the pivot arms 5, 6 in a coordinated manner, the container C is then moved to the position on the chassis 2 that is shown in figure 7C via the position shown in figure 7B. The chassis 2 is for example provided with twist locks as known per se, which can be locked in the openings present in the container C, so that the container C is firmly 10 connected to the chassis 2.
Figures 8A-8C show rear views of the sideloader 1 upon placement of a container C on the left-hand side L on top of another container C already present on the left-hand side L. The container C that is already present on the surface 37 is spaced from the chassis 2 by a distance that is smaller than 15 the distance from the support foot 31 to the chassis 2.
In the position shown in figure 8A, the container C to be placed is positioned above the chassis 2.
By extending and retracting the second arm portion 15 and pivoting the pivot arms 5, 6 in the opposite direction of arrows P8, P9 in a 20 coordinated manner, the container C is then moved to the position on top of the lower container C shown in figure 8C via the position shown in figure 8B. The container is C can subsequently be locked together using means that are known per se.
Figure 9 is a graph showing the range of the lifting device 3, in which 25 the movements in the X-direction and the Z-direction of the pivot shaft 17 of the connecting piece 16 upon pivoting of the first pivot arm 5 and the second pivot arm 6 and extension of the second pivot arm 6 are plotted on the X-axis and the Z-axis, respectively, with the support plates 21, 22 positioned a maximum distance from the plane V. WO 2016/124598 17 PCT/EP2016/052184
Line 51 indicates the movement in the X, Z-direction on the left-hand side L at a minimum length of the pivot arm 6. Line 52 indicates the movement in the X, Z-direction on the right-hand side R at a minimum length of the pivot arm 6. Line 53 indicates the movement in the X, Z-direction on the left-hand side L and the right-hand side R at a maximum length of the pivot arm 6. Line 54 indicates the movement in the X, Z-direction on the right-hand side R upon extension of the second pivot arm 6 and maximum pivoting of the pivot arm 6.
The two lifting devices 3 located on either side of the container C operate in unison and can be controlled separately or simultaneously.
The lifting devices 3 can be placed on any chassis, for example a truck, a train, another mobile vehicle or a fixed platform.
It is also possible to detachably connect the container to an end of the connecting piece 16 using different means, for example a top lock or hoisting belts.
It is also possible to move loads other than containers, for example bulk packages or skips, by means of the lifting devices 3.
It is also possible to use elements other than pins as locking means, for example movable plate-shaped element or a rotatable element.
According to another possibility, the movable pin is provided in the frame and the opening is provided in the first pivot arm.
It is also possible to provide the opening 46 in the frame 4 of the lifting device 3 on a side of the first pivot arm 5 of the lifting device 3 that faces the other lifting device 3.
It is also possible to provide two pins 45, which are positioned in openings 46 present on either side of the first pivot arm 5 in the frame 4 for locking the first pivot arm 5 in place.
Using the sideloader 1 it is also possible to place loads on a trailer positioned on the left-hand side L and/or on the right-hand side R of the chassis. WO 2016/124598 18 PCT/EP2016/052184
