Embodiment Construction

[0029] according to figure 1 The illustration in the figure shows a large manipulator 1 for a vehicle-mounted concrete pump with a folding articulated mast 2 with a turntable 4 rotatable about a vertical axis 3 and a plurality of mast sections 5, 5a, 5b, 5c. Each mast section 5, 5a, 5b, 5c can be driven at the hinged joint 6, 6a, 6b, 6c relative to the adjacent mast section 5, 5a, 5b, 5c or the turntable 4 around the hinge axis by means of a drive The unit (not shown) pivots. By means of the large manipulator 1, the fluid concrete is conveyed from the concrete pump 17 to the top of the mast 15 through a concrete supply line (not shown), wherein the concrete supply line terminates in a terminal hose (not shown), so that when passing through this vehicle-mounted concrete When pumping concrete, large distances and heights can be bridged with the aid of the large manipulator 1 .

[0030] figure 2 The last mast section 5c forming the mast top 15 is schematically shown, which ha...

Abstract

A large manipulator (1) with a folding articulated mast (2) with a turntable (4) rotatable about a vertical axis (3) and a plurality of mast sections (5, 5a, 5b, 5c), Wherein, a mast section (5, 5a, 5b, 5c) can be positioned relative to an adjacent mast section (5, 5a, 5b, 5c) or a turntable at a hinged joint (6, 6a, 6b, 6c) about a corresponding hinge axis (4) Pivoting, at least one mast section (5, 5a, 5b, 5c) is formed by a hollow structure (7) made up of interconnected wall elements (8, 8a, 8b, 8c). The object of the present invention is to reduce the weight of such large manipulators. For this purpose, the invention proposes to incorporate a recess (11) in at least one of the wall elements (8, 8a, 8b, 8c), wherein the depth of the recess is smaller than the material of the wall element (8, 8a, 8b, 8c) thickness, so that the wall elements (8, 8a, 8b, 8c) are closed in the region of the recess (11).

Description

technical field [0001] The invention relates to a large manipulator with a folding articulated mast having a turret pivotable about a vertical axis and a plurality of mast sections, wherein each mast section is respectively movable at an articulated joint about an articulated axis relative to a corresponding Pivoting adjacent mast sections or turntables, wherein at least one mast section is formed by a hollow structure of wall elements connected to one another. Background technique [0002] Due to growing demand, the development of such large manipulators required greater mast lengths, however, the dead weight of large manipulators limited these attempts. [0003] It is known from the prior art to provide a truss-like structure on mast sections of large manipulators in order to save weight. However, their disadvantage is that they form an open structure, so dirt and water can enter and build up water or dirt on the surface. In addition, the inside of an open mast section i...
