Vehicle crane with a telescopic boom, as well as process for assembling and disassembling the anchor supports of the telescopic boom

Process for assembling or disassembling anchor supports (6) a telescopic boom (3) of a vehicle crane, having the following assembly steps:

• Grasping and hoisting of the disassembled anchor supports (6) by the boom (3) itself from a low-bed trailer or similar equipment;
• Depositing of the disassembled anchor supports (6) on brackets (9) on a vehicle chassis at intervals from one another and in predetermined position relative to the vehicle crane;
• Positioning of the boom (3) between the anchor supports (6) deposited on brackets (9);
• and
• Attachment of anchor supports (6) to an anchor support connector (5) of one of the boom (3) sections.

Process for disassembling anchor supports (6) of a telescopic boom (3) of a vehicle crane, having the following disassembly steps:

• Positioning of boom (3) with the anchor supports (6) mounted on it between two brackets (9) on a vehicle chassis, until anchor supports (6) are lying on the brackets or are directly above the brackets;
• Depositing of the anchor supports (6) on the brackets (9), whereupon the anchor supports are detached from the boom;
• Movement of the boom (3) without anchor supports (6)
• Grasping and hoisting of the disassembled anchor supports (6) lying on brackets (9) by the boom (3) itself, and
• Depositing of the anchor supports (6) on a transporter.

A mobile crane having a telescopic boom (3) which can be tilted about a horizontal axis and rotated about an upright axis, said mobile crane having

• an attachment section (4),
• telescopic sections (16, 17, 18, 19) which can be telescoped out of the attachment section (4), and
• two support braces (6), which are pivotally mounted in an articulated manner on one of the sections (4, 16, 17, 18, 19) and moveable between a transport position in which the support braces (6) are substantially parallel to each other and an upright operating position in which the anchor supports (6) are in a substantially V-shaped configuration,
• wherein, when the telescopic boom is in a substantially horizontal position the support braces (6) can be dismantled from the telescopic boom and can be deposited on spaced-apart brackets mounted on a chassis of the mobile crane on a right side and a left side of the mobile crane chassis adjacent the telescopic boom (3) from which brackets the support braces (6) can be moved by the telescopic boom (3) itself after the telescopic boom has been tilted to an upright position.
