FRAME WITH A BOOM PEDESTAL FOR MOUNTING A THICK MATTER DISTRIBUTION BOOM
The subject of the present invention is a frame (12) with a boom pedestal (17) for mounting a thick matter distribution boom (20) and having a support profile (13) for receiving and transmitting a force flow generated by the weight force of the thick matter distribution boom (20). The boom pedestal (17) has two tab elements (21, 22) which project downwards from the boom pedestal (17) and which each have a through-hole (23, 24), wherein the support profile (13) comprises a bolt receptacle (14) aligned with the through-holes, and wherein a bolt element (15) for connecting the boom pedestal (17) to the support profile (13) is guided through the through-holes (23, 24) and the bolt receptacle (14). The invention further relates to a corresponding thick matter pump equipped with said frame. The transportation effort required in production can be reduced by means of the bolt connection.
The present invention relates to a frame for carrying a concrete-distribution boom, the frame comprising a carrier profile (13) which has: at least one force-absorption region (16, 17), for absorbing a flow of force exerted by the concrete-distribution boom; and a force-dissipation region (18), which is spaced apart in the longitudinal direction of the carrier profile (13), for dissipating the flow of force into the ground. The carrier profile (13) comprises at least two profiled sheets (20, 21), which are each bent along at least one bending axis (26, 27, 31) and are assembled along at least two connection lines (22, 23) to form a hollow profile. The carrier profile formed by bent profiled sheets is simple to produce and flexible to use.
