TRUCK-MOUNTED CONCRETE PUMP HAVING AN UNDERRIDE GUARD
The invention relates to a truck-mounted concrete pump (1), which has a concrete feeding funnel (2) at the rear end, which concrete feeding funnel is accessible from behind, and a concrete conveying line (4) below said concrete feeding funnel (2), which concrete conveying line leads from the center of the truck-mounted concrete pump (1) to a side of the truck-mounted concrete pump (1), wherein the region below and/or behind the concrete feeding funnel (2) is covered by an underride guard (5), which has an underride guard rail (6), which extends across the width of the truck-mounted concrete pump (1) and which is supported on the rear end of the truck-mounted concrete pump (1) pivotably about a pivot axis (9) perpendicular to the direction of travel in such a way that the underride guard rail allows access to the concrete feeding funnel (2) in a passive pumping operation position or covers the underride region at the rear end of the truck-mounted concrete pump (1) in an active driving position. According to the invention, in order to improve and simplify the fastening of the underride guard rail (6), the underride guard rail (6) is pivotably supported on the truck-mounted concrete pump (1) exclusively in a region of the truck-mounted concrete pump (1) not covered by the concrete conveying line (4).
For dynamically loaded components, in particular hydraulic cylinders, that have at least one weld seam, fatigue of the weld seam and an associated loss of strength can occur over time, in particular if the root of the weld seam is heavily loaded. Fine cracks in the region of the root, for example, are a frequent cause of material failure. In order to improve the strength of rotationally symmetric, welded components, it is proposed that a narrowed web (7) is formed in a region adjacent to the weld seam (10) on a first part (2; 4) and/or on a second part (3; 5) of the component, which parts are connected to each other by means of the weld seam (10), wherein the wall thickness (t1, t2) of the first and/or second part (2; 4, 3; 5) in the region of the narrowed web (7) is less than the depth (ts) of the weld seam (10). Thus, the force flow can at least partially bypass the root (11) so that the welded joint (10) is less heavily loaded.
For vehicles with a boom, lateral support is required as soon as work is performed with the boom. While work is performed with the boom, there is a risk of the vehicle tipping over, in particular if the boom is laterally swung out very far. It is expedient to provide a ground contact sensor system in order to reduce the risk of tipping. For this purpose, the invention provides a supporting device (10) for supporting the vehicle on the ground, comprising - a support (12) connected to the mobile device, - a hydraulic cylinder (13), which is supported on the support (12) and which can be moved between an upper end position and a lower end position in relation to the support (12), - a supporting foot (12a), which can be lowered and raised by means of the hydraulic cylinder (13), and - a sensing device (19), which produces a supporting-load-dependent signal. According to the invention, the sensing device (19) produces the supporting-load-dependent signal by means of a proximity switch, which responds when the distance of the hydraulic cylinder from the upper end position of the hydraulic cylinder falls below or exceeds a specified value.
