The within invention concerns a vehicle crane with a telescopic boom that can move on a horizontal axle and rotate on an upright axle with a pivot section, telescoping sections that can telescope out of the pivot section, and also with two anchor supports flexibly housed on one of the sections so that they can pivot out of transportation position, in which they are folded essentially parallel to each other against the section, and can be spread apart into an erect, particularly V-shaped, operation position. The invention also concerns a process for assembling or dissembling said anchor supports of the telescoping boom of the vehicle crane. According to the invention, when the boom is lying in essentially horizontal position, the anchor supports can be disassembled, are positioned on brackets provided next to the boom, and after the boom is raised are raised from the brackets and loaded by the boom itself.
Vehicle crane with a telescopic boom (3) that can luff on a horizontal axle and rotate on an upright axle with a pivot section (4), telescoping sections (16, 17, 18, 19) that can telescope out of the pivot section (4), and also with two anchor supports (6) flexibly housed on one of the sections (4, 16, 17, 18), so that they can pivot out of transportation position, in which they are folded essentially parallel to each other against the section, and can be spread apart into erect, particularly V-shaped, operating position, characterized by the fact that when the telescoping boom (3) is lying in essentially horizontal position the anchor supports (6) can be removed from it and positioned on brackets provided next to boom (3), from which said brackets the anchor supports (6) can be raised and/or unloaded by the telescoping boom (3) after appropriate luffing of boom (3).
Vehicle crane according to the foregoing claim, in which pressure cylinders for pivoting the anchor supports (6) are pivoted to the anchor supports and can be disassembled, as a unit together with anchor supports (6), from the telescoping boom (3).
Vehicle crane according to the foregoing claim, having on each anchor support (6) a telescoping boom connector (7) for detachable connection with the pertinent boom section, in particular a collar (5) thereof, having between boom connector (7) and individual anchor support (6) at least one pivoting axle and/or one pressure cylinder that can be pivoted on one hand to the boom connector (7) and on the other hand to the anchor support (6).
Vehicle crane according to one of the foregoing claims, in which the anchor supports (6) can be pivoted directly to the individual boom section free of cross-connections, erection bridges, and similar arrangements.
Vehicle crane according to one of the foregoing claims, in which positioning components are provided on the brackets (9) to bring the anchor supports (6) into a predetermined assembly position when anchor supports (6) are laid on brackets (9).
Process for assembling or disassembling anchor supports (6) on a telescoping boom (3) of a vehicle crane, particularly according to one of the foregoing claims, with the following assembly steps:
Process according to the foregoing claim, in which the anchor supports (6) are laid on the brackets (9) in essentially horizontal position and/or parallel to one another, and the boom (3) is moved horizontally lengthwise along the vehicle.
Process according to one of the foregoing claims, in which instead of the said assembly steps the following disassembly steps are performed:
