- the ground wheel groups are displaced in a direction of parked so that the machine can ride in its direction of length over the loading platform 153 of the transport vehicle so that the building section as a whole is moved to above the loading platform 153. Then the ground wheel groups are displaced relatively to the carrying arms so that the frame of the machine with the carrying arms and the building section held by the arms moves downwards until the building section bears on the loading platform 153, as shown in FIG. 7. The arms are then moved to withdraw the supporting feet from below the building section, the carrying arms 100 to 103 being pivoted in the direction of the arrow 145 (FIG. 3) about the pivotal shafts 108 and the carrying arms 104 to 107 being pivoted in the direction of the arrow 146 about their pivotal shafts.

- the carrying arms hold the building section on its bottom face for displacement.
- the load produced by the section is approximately equal to the load exerted at its place in the building. This is advantageous to the manufacture of the sections, since in this case no special precautions have to be taken for transport by the machine.
- By arranging the main girder of the machine at the top a section can be engaged effectively from the main girder on either side by the carrying arms.
- the motors and other gear can be advantageously supported by the main girder.
- By arranging the main girder centrally extending in the direction of length of the machine a satisfactory distribution of load in the machine is obtained.
- the height of the main girder above the ground is adjustable so that a section of height of about 3 ms can be lifted and placed on a transport vehicle.
- the distance over which the main part of the machine can be displaced in a direction of height can be chosen to some extent by means of the length 151 (FIG. 1) of the supporting shafts of the ground wheel groups.

DESCRIPTION OF THE PREFERED EMBODIMENT The machine shown in FIGS. 1 to 6 has a main girder 1, extending in the direction of length of the machine. This main girder l is fabricated from corner beams 2, 3, 4 and a further beam not visible, extending in the direction of length of the girder, a sheet upon side 5, and sheet sidewalls 6. At a distance indicated by dimension 7 inwards from one end of the main girder 1 transverse beams 8 and 9 extend at right angles from the girder on either side thereof. At a distance indicated by dimension 10 inwards from the other end of the main girder 1 similar transverse beams 11 and 12 also extend at right angles from the main girder l on either side thereof. The dimensions 7 and 10 are equal, each amounting to about one seventh of the over-all length 131 of the main girder 1. The main girder 1 and the transverse beams 8, 9, 11 and 12 are horizontal and constitute the top part of the machine.
The free end portions of the transverse beams 8, 9, 11 and 12 mount, on their lower faces, the upper ends of supporting legs l3, 14, and 16, to each of which a vertical shaft (legs 15 and 16) or 137 (legs 13 and 14) is journalled, each of which in turn mounts a ground wheel group formed by four ground wheels. To this end, and referring to the leg 15 which has a ground wheel group 17, at its lower end of shaft 20 carries an inverted U-shaped bracket 21, the web 28 of which is secured to the shaft 20 and the two limbs of which are designated 24 and 26. At the lower ends of the limbs 24 and 26 rocking arms 22 and 23 pivot about horizontal stub shafts 29 and 30. The mounting of the rocking arms 22 and 23 is reinforced by stiffening arms and 27, extending parallel to the limbs 24 and 26, the rocking arm 22 being pivotal between the lower ends of the limb 24 and the arm 25 and the rocking arm 23 being pivotal between the lower ends of the limb 26 and the arm 27. The corresponding free ends of the rocking arms 22 and 23 carry stub shafts 33 and 34, and 40, A, which respectively pivotally support brackets 32 and 39 extending in the intended direction of travel of the machine. The brackets 32 and 39 respectively embrace pairs of ground wheels 35, 36, and 38, 42, respectively mounted on, for rotation in common, horizontal axles 37 and 41, these axles being respectively journalled in the brackets 32 and 39. The ground wheels 35, 36 and 38, 42 thus form two pairs of ground wheels, which form together the ground wheel group 17 on the vertical shaft 20 of the supporting leg 15. Like the leg 15 the shaft 20 of the leg 16 carries an inverted U-shaped bracket 19 having a ground wheel group 18 formed by four ground wheels 43, 44, 45 and 46. The ground wheel group 18 is arranged in the same manner as the ground wheel group 17 so that further description may be omitted.
By means of the shaft 137 the leg 13 is provided with a bracket 47, similar to the bracket 21. The bracket 47 carries a ground wheel group 48 of four ground wheels in the same manner as the ground wheels 35, 36, 38 and 42 on the bracket 21. Similarly the supporting arm 14 is provided with a bracket 49 having a group of ground wheels 50. The construction of this ground wheel group is similar to that of the ground wheel group 17 and it will therefore not be described in detail.
Thus the machine has four ground wheel groups, two of which 48 and 50 are located at the front with respect to the intended direction of forward movement 98 of the machine, and the remaining two of which 17 and 18 constitute the rearmost ground wheel groups of the machine. The foremost ground wheel groups 48 and 50 are coupled with a prime mover and constitute driven ground wheels. Thus, referring to FIGS. 5 and 6, the ground wheel group 48 comprises one pair of coupled ground wheels 56 and 57 and one pair of coupled ground wheels 58 and 59. The ground wheels 56 and 57 are mounted in a bracket 99, similar to the bracket 32 in FIG. 3. The ground wheels 58 and 59 are mounted in a bracket 97, similar to the bracket 39 of FIG. 3. The bracket 99 is provided with a support hood 51 which extends around the wheels 56 and 57 and is connected with the two opposite limbs of the bracket 99. The support hood 51 carries a hydraulic motor 52, which is linked by means of a chain sprocket 53 and a chain 55 to a chain sprocket 54 which is coupled with the pair of ground wheels 56 and 57. The bracket 97 has a support hood which extends around the wheels 58 and 59 between the front and rear limbs of the bracket 97. The support hood 60 carries a hydraulic motor 61 having a chain sprocket 62 which is linked by a chain 64 to a chain sprocket 63 which is coupled with the pair of ground wheels 58 and 59. The motors 52 and 61, as will be apparent from the side view of FIG. 5, are arranged relatively on the sides of a V with respect to the rotational axis of the ground wheels, located on radial lines 135 and 136. At the front of the machine the main girder 1 carries a pump which constitutes the prime mover for the hydraulic system of the machine and which drives the hydraulic motors 52 and 61 through ducts 71 and 72, 73 and 74 respectively. The ground wheel group 50, like the ground wheel group 48, is similarly driven. Preferably all the ground wheels have solid tires.
On the top of the machine a steering cylinder 80 of a hydraulic steering mechanism is mounted for controlling the four ground wheel groups 17, 18, 48 and 50'at the lower ends of the supporting legs 15, 16, 13 and 14. The steering cylinder 80 is a hydraulic device also fed from the hydraulic system of the machine and is coupled with arms 132 and 133 pivotable about a common shaft 81, the arm 133 being coupled through a coupling rod 82 with a vertical shaft 83. The shaft 83 is located perpendicularly above the vertical support shaft 137 of the ground wheel group 48 and is connected therewith for'turning the shaft 137 about its longitudinal center line. The shaft 83 is also coupled through a steering rod 84 with a vertical shaft 85 which is in line with and connected to the vertical shaft supporting the ground wheel group 50 for turning this last-mentioned shaft about its longitudinal center. The steering cylinder 80 is connected via the arm 132 and a coupling rod 86 with a vertical shaft 87 connected through a further steering rod 88 with a vertical shaft 89. The shafts 87 and 89 are respectively coupled with the vertical shafts 20 of the ground wheel groups 17 and 18.
At the front of the machine a control-platform 90 is provided with a drivers seat 91 and a steering wheel 94 hydraulically connected with the steering cylinder 80. From the control-platform 90 a control-member 92 is coupled with the driving motors of the ground wheel groups 48 and 50.
The machine has eight carrying arms 100 to 107 pivoted to the main girder 1 with four carrying arms disposed equi-spaced apart on each side of the girder l. The arm 100 is provided with a stair 170 and a railing 172 to be able to reach the control-platform 90. The foremost and rearmost carrying arms are fastened to the front and the rear ends respectively of the main girder 1. As will be described more fully for one carrying arm 103, the carrying arms are secured to the main girder 1 so as to be pivotable about horizontal pivotal shafts 108. These pivotable shafts 108 are parallel to the main girder l and to the direction of movement 98.
The carrying arm 103 has at its root a supporting bearing 109 extending parallel to the main girder l and arranged between supports 110 and 111 fastened to the main girder 101. The carrying arm 103 is cranked so that it provides a substantially horizontal portion 112 and a substantially vertically extending portion 113. The connection of the portion 112 with the portion 1 13 is reinforced by a fillet 114. Between the portion 112 and the supports 110 and 111 on the main girder 1 an actuating mechanism formed by a hydraulic jack 115 is provided, secured to the supports 110 and 111 so as to be pivotable about a shaft 117. The other end of the jack 115 is secured to the portion 112 of the supporting arm 103 so as to be pivotable about a pivotal shaft 116. The lower, free, end of the supporting arm 113 is provided with an extension 118. This extension 118 is formed by two bent strips 119 and 120 shown best in FIG. 4. The extension 118 is secured by means of the strip 120 to the lower, free, end of the supporting arm 113. The ends of the strips 119 and 120 remote from the supporting arm 113 are secured to each other and constitute a supporting foot over a length 121. The strip 120 is provided with a screening hood 122, a vertical side 123 of which forms a stop. The side 123 has an opening through which a feeler 124 extends so that it projects out of the side 123 above the base of the supporting foot. The feeler 124 is one portion of a cranked rocker arm adapted to move about a pivotal shaft 125 and co-operating with an electric contact 126. The end 128 of the rocker arm remote from the feeler 124 cooperates with a compression spring 127, which acts to urge the end 128 of the rocker arm against the strip 120.
Each of the carrying arms to 107 is connected with the main girder l by a hydraulic jack such as the jack and each has a supporting foot as just described at its free end. The jacks 115 are controllable in common from the drivers seat by means of a control-arm 93 so that the carrying arms can be moved to any one of a plurality of positions relative to the machine frame. On either side the drivers platform 90 has a row of signalling lamps of an indicator system, the number of which corresponds with the number of carrying arms. With respect to the direction of movement 98 the drivers platform 90 has on the left-hand side four signalling lamps 155 and on the right-hand side four signalling lamps 156. The signalling lamps 155 cooperate with the feeler arms 124 of the carrying arms 100 to 103 and the signalling lamps 156 co-operate with the feeler arms 124 of the carrying arms 104 to 107.
The machine described above is capable of displacing large building sections in a simple manner. The machine is particularly suitable for large, space-bounding building sections to be employed to erect a building, being building sections that are wholley or partly prefabricated and bound spaces so that a section forms part of the space of a building, for example, part of one or more rooms. A section has a floor, walls and a top which may form a ceiling and, for example, a roof. The Figures illustrate how a building section is carried in the machine to be displaced thereby. The width 140 of the section is about 2.50 ms (FIG. 3). The section has a length of about 11 ms (FIG. 1), corresponding with the length 141 of the machine.
The building sections can be picked up by the carrying arms of the machine. For this purpose the machine is moved to straddle a building section and the carrying arms are pivoted inwardly so that the supporting feet at the lower, free, ends of the carrying arms are moved to beneath the bottom of the building section so that the supporting feet are located, by the distance 121 (FIG. 4), beneath the building section. When the supporting feet are thusin place beneath the building sections, the main part of the machine is lifted as a whole by displacing the four ground wheel groups in a direction of height with respect to the carrying arms. The section is thus displaced in a direction of height. For this displacement of the ground wheel groups the shafts of the ground wheel groups, such as the shaft 20, are shifted in a direction of height with respect to the supporting arms 15. This displacement of the shafts with respect to the supporting arms is performed by hydraulic motors (not shown) disposed in the supporting arms, connected by transmission means with the shafts of the ground wheel groups, and fed from the hydraulic system 70. Owing to this displacement of the ground wheel groups with respect to the supporting arms, the whole machine frame is lifted so that the arms with the building section bearing on the supporting feet of the arms are moved upwards. Although in this form the whole frame of the machine is moved upwards or downwards for the vertical displacement of a building section, it is possible, as an alternative, to mount the carrying arms on the frame, for example, on the main girder 1, so as to be displaceable in a direction of height with respect thereto. When the building section is elevated to a sufiicient extent from the ground, the machine can be displaced as a whole in a horizontal direction by driving the ground wheel groups 48 and 50 by means of the hydraulic motors associated therewith. In this way building sections can be transported by the machine to, for example, a storeroom.
The machine is also particularly suitable for loading or unloading the building sections on or off a transport vehicle, either from or to a storeroom, or directly from their place of manufacture onto a transport vehicle. FIG. 7 illustrates how a building section can be placed by the machine on a transport vehicle 152. In order to arrange the building section on the transport vehicle,
the ground wheel groups are displaced in a direction of parked so that the machine can ride in its direction of length over the loading platform 153 of the transport vehicle so that the building section as a whole is moved to above the loading platform 153. Then the ground wheel groups are displaced relatively to the carrying arms so that the frame of the machine with the carrying arms and the building section held by the arms moves downwards until the building section bears on the loading platform 153, as shown in FIG. 7. The arms are then moved to withdraw the supporting feet from below the building section, the carrying arms 100 to 103 being pivoted in the direction of the arrow 145 (FIG. 3) about the pivotal shafts 108 and the carrying arms 104 to 107 being pivoted in the direction of the arrow 146 about their pivotal shafts. These movements of the carrying arms are effected by actuation of the hydraulic jacks 115.
When the supporting feet have. been removed from beneath the section, the transport vehicle with the section located thereon can be driven from beneath the machine or the machine can be driven away from the transport vehicle. For picking up a section the supporting feet can be inserted beneath the section by actuating the hydraulic cylinders 115 so that the carrying arms located on opposite sides of the main girder 1 approach each other. The feelers 124 initiate signals observable at the drivers seat when the supporting feet have completely covered the distance 121 beneath the building section, since when the carrying arms reach the positions which the building section touches the stops 123, the feelers 124 are moved around their pivotal shafts against the pressure of their springs 127 to switch the electric contact 126 so that the signalling lamps 155 and 156 near the drivers seat are illuminated. The feelers 124 together with the signalling lamps constitute an indicator system for informing the driver of correct engagement of the supporting feet with the section. The movement of the carrying arms about their pivotal shafts is then stopped by the driver. The feelers may, as an alternative, be coupled so that they automatically stop the movement of the carrying arms when the stops 123 come into contact with the section. At the drivers seat it can thus be checked that the supporting feet are located in a correct manner beneath the building section and the building section is satisfactorily supported on the feet of the carrying arms. A displacement of the supporting feet relative to the building section such that the distance 121 is not fully employed is immediately perceivable since the feelers 124 are then no longer in contact with the section and the signalling lamps 155 or 156 near the drivers seat will go out.
The carrying arms hold the building section on its bottom face for displacement. The load produced by the section, particularly if it is to be used for part of a story, is approximately equal to the load exerted at its place in the building. This is advantageous to the manufacture of the sections, since in this case no special precautions have to be taken for transport by the machine. By arranging the main girder of the machine at the top, a section can be engaged effectively from the main girder on either side by the carrying arms. The motors and other gear can be advantageously supported by the main girder. By arranging the main girder centrally extending in the direction of length of the machine a satisfactory distribution of load in the machine is obtained. Owing to the shape of the carrying arms by which the upper portion 112 is substantially horizontal and the remaining portion 113 can be arranged at a small angle to the perpendicular, so as to be inclined downwards towards the center of the machine (see FIG. 3), the distance between the upper parts of the portion 1 13 of the carrying arms to 103 and the carrying arms 104 to 107 is greater above the lower free ends of the carrying arms than between the lower free ends. This facilitates picking up a section, because a section may be wider at the top, for example, owing to a projecting roof edge, than at the bottom, as is shown at 147 in FIG. 3. From the platform at the front high up in the machine the driver can satisfactorily supervise operation of the machine. The height of the main girder above the ground is adjustable so that a section of height of about 3 ms can be lifted and placed on a transport vehicle. The distance over which the main part of the machine can be displaced in a direction of height can be chosen to some extent by means of the length 151 (FIG. 1) of the supporting shafts of the ground wheel groups.
