Embodiment Construction

[0026] exist figure 1 The truck-mounted concrete pump 10 illustrated in includes a transport vehicle 12 with a cab 14 and a frame 16 , a superstructure frame (Aufbaurahmen) or load-carrying structure 18 , a multi-linkage that can be rotated about a vertical axis (Hochachse) by means of a rotation mechanism 20 Mehrgliedrigen concrete distribution rod 22, a delivery pump 26 configured as a double-cylinder piston pump for conveying liquid concrete, coupled between the filling funnel 24 and said concrete distribution rod 22, and a plurality of support legs 28, 30 It serves to support the load-bearing structure 18 in a working position provided for the concrete pouring operation. In addition, in order to achieve compensation of undesired rotational deflections or deflection vibrations of the load-bearing structure 18 during the pouring operation, a figure 1 The compensating means 32 are only shown symbolically.

[0027] In the supporting configuration shown, the rear supporting l...

Abstract

The invention relates to a mobile working machine with a vehicle (12), a concrete distribution bar (22) which can be rotated via a rotation mechanism (20) on a load-carrying structure (18) fixed at the vehicle, and a plurality of Support legs (28, 30) at the load-bearing structure (18) serve to support the load-bearing structure (18) in a working position, wherein it is proposed to be configured for compensating the load-bearing structure (18) from the A compensation mechanism (32) for a rotational offset in a working position, which has a detection unit (48) for detecting the rotational offset and acts on at least one support leg (28) via a corresponding control element (42) ) on to reduce the rotational offset.

Description

technical field [0001] The invention relates to a mobile working machine (fahrbare Arbeitsmaschine), in particular a truck-mounted concrete pump, with a vehicle, a concrete distribution rod (Betonverteilermast) which can be rotated via a rotating mechanism on a support structure fixed to the vehicle, and a plurality of Support legs at the load-bearing structure serve to support the load-bearing structure in a working position. Furthermore, the invention relates to a method for the low-vibration operation of such a mobile work machine. Background technique [0002] In a mobile concrete pump of this type (DE-102 46 447 A1), the load-bearing structure is placed on the frame (Fahrgestell) of the truck chassis. The carrier structure forms an interface with its rod seat or pivot mechanism between the distributing rod and the support leg. In this case, the load moment generated by the distribution rod is distributed via the rod seat to the support leg and introduced into the grou...
