One of the stations comprises a turning device for rotating the car around its longitudinal axis, whereby the bottom side of the car is accessible from above. The turning device comprises a pair of clamping bars (18) that can be pushed towards and away from each other by pivotable legs (17) supported by a bridge (13) being pivotably supported by a framework (2), in such a way that the bridge is rotatable around its longitudinal axis and adjustable in height. At the end of the transport track (31) there is a press for crushing the body of the scrapped car, substantially consisting of metal. ## Claims ### Claim 1 A device for scrapping cars, said device comprising: a plurality of stations; conveyor trolleys guiding a car through the plurality of stations and stopping at least one station; wherein at least one of the stations includes a turning device raising a car and rotating the car about its longitudinal axis such that a bottom of the car becomes accessible from above, the turning device comprising: a framework; a bridge pivotally mounted on the framework such that the bridge is rotatable about its longitudinal axis; a bridge rotating and vertical adjusting mechanism adjusting and rotating the bridge in a vertical direction; at least one supporting member having a first leg and a second leg, the first and second legs being rotatably supported on the bridge at first ends of the legs; a pair of clamping bars having clamping members, the clamping bars being connected to the at least one supporting member such that the clamping bars can be pushed toward and away from each other; and a leg pivoting mechanism pivoting the first and second legs such that the clamping bars can be moved toward and away from each other. ### Claim 2 (depends on 1) The device according to claim 1, wherein the first leg is rotatably connected to the bridge by a first pivot, and the second leg is rotatably connected to the bridge by a second pivot, the first pivot being spaced from the second pivot. ### Claim 3 (depends on 1) The device according to claim 1, wherein second ends of the first and second legs are connected to each other by a cylinder and by a coupler extending between the first and second legs, such that upon operation of the cylinder, the first and second legs are rotated over substantially equivalent angles. ### Claim 4 (depends on 3) The device according to claim 3, wherein the coupler includes at least one coupling plate having a first pivot point and a second pivot point, and is pivotally connected at the first pivot point to the first leg and at the second pivot point to the second leg. ### Claim 5 (depends on 4) The device according to claim 4, wherein the first pivot point of the coupling plate is located in a first direction from the first pivot, and the second pivot point of the coupling plate is located in a second direction, opposite the first direction, from the second pivot; and a center of a connecting line between the first and second pivot points of the coupling plate coincides with a center of a connecting line between the first and second pivots. ### Claim 6 (depends on 1) A device according to claim 1, including a frame surrounding the framework, and wherein the framework is pivotally connected to the frame such that upon pivoting the framework, the bridge, being connected to the framework, is adjusted in the vertical direction. ### Claim 7 (depends on 6) A device according to claim 6, further comprising an assisting mechanism, in the form of a chain or a hydraulic cylinder, assisting in rotating the bridge. ### Claim 8 (depends on 7) A device according to claim 7, wherein the assisting mechanism is connected to a spring-tensioned locking pin and is removed from a hole in the frame before the bridge is free to rotate. ### Claim 9 (depends on 8) A device according to claim 8, wherein a plurality of holes are provided in the frame for receiving the locking pin. ### Claim 10 (depends on 1) A device according to claim 1, wherein the conveyor trolleys include longitudinal edges having trolley supporting members which are pivotable up to 180.degree.; and the trolley supporting members are spaced from each other in a longitudinal direction of the conveyor trolley such that in an outward pivoted state of the trolley supporting members, the trolley supporting members extend substantially horizontally and support wheels or axles of a car to be scrapped, and such that in an inward pivoted state, the trolley supporting members partially overlap and extend within the conveyor trolley. ### Claim 11 (depends on 10) A device according to claim 10, further comprising: a conveyor track having a beginning portion, an end portion, a higher track portion, a lower track portion, and a vertically adjustable track portion; and chain drivers mounted to chains for driving the chains; wherein the conveyor trolleys are provided with means for engaging the chain drivers at the beginning portion and the end portion of the conveyor track; and wherein the vertically adjustable track portion is adjusted by at least a first chain which is movable in opposite directions, the upper conveyor track portion is provided with a second chain movable in a single direction, and the lower conveyor track portion is provided with a third chain which is movable in a single direction. ### Claim 12 (depends on 11) A device according to claim 11, further comprising a releasably coupler coupling the conveyor trolleys on the upper conveyor track portion to the second chain. ### Claim 13 (depends on 1) A device according to claim 1, further comprising a press mounted at an end of the conveyor track, the press pressing flat a remaining part of the car. ### Claim 14 (depends on 13) A device according to claim 13, wherein the press comprises: a fixed bearing plate; and at least one clamping jaw pivotally connected to the bearing plate at longitudinal edges of the bearing plate; wherein the at least one clamping jaw is pivoted from a bearing plate releasing position, in which a car body is placed thereon, to a compressing position in which a car body is compressed; and wherein, in the compressing position, the longitudinal edges of the at least one clamping jaw are above the bearing plate and substantially in line with each other. ### Claim 15 (depends on 14) A device according to claim 14, further comprising a support mounted near a longitudinal edge of the bearing plate and extending in an upward direction; and an arm pivotally mounted to the support at a distance above the bearing plate and above the at least one clamping jaw when the at least one clamping jaw is in an upward directed position; wherein the arm is pivoted toward the bearing plate to pivot the at least one clamping jaw and to press the car body toward the bearing plate, thus crushing a roof of a car body in a longitudinal direction of the car body. ### Claim 16 (depends on 1) A device according to claim 1, further comprising: a waste glass container including a casing having a side wall, the side wall being provided with a slot into which a car door is inserted; an impact device including a sharp pin, and provided above the waste glass container such that the sharp pin exerts an impact on a window of the car door, and splinters of the window fall into the waste glass container.
