Embodiment Construction

[0027] in figure 1 Shows a construction machine with a safety device according to the invention. The construction machine 1 is designed as a mobile ground drilling equipment. It has a crawler type walking device forming a supporting unit 10. The upper compartment 11 of the construction machine is arranged on the supporting unit 10. The upper box 11 is pivotally arranged on the supporting unit 10 about the vertical axis 3. Rod supports 12 are arranged on the upper compartment 11 again, which support a rod 14 and connect it to the upper compartment 11. The rod support 12 can now be pivotally arranged about a horizontally extending axis. By pivoting the lever support 12, the lever 14 can be adjusted radially relative to the upper compartment 11 and thus relative to the support unit 10. A sliding carriage 15 that can move vertically is arranged on the rod 14. An operating unit 18 is provided on the carriage 15, which forms a drill drive for the drill rod 19.

Abstract

The safety device has a detector for detecting instantaneous position of an actuator unit (18) of a construction machine (1) relative to the carrier unit (10) of the construction machine. A display device (20) is provided, with which the instantaneous position of the actuator unit relative to the carrier unit is displayed. An evaluation unit (22) is provided through which an adjustable range of the actuator unit is ascertained depending on an input value. The adjustable range together with the instantaneous position of the actuator unit is displayed by the display device.

Description

Technical field [0001] The invention relates to a safety device for a construction machine according to claim 1, the construction machine having a supporting unit and an operating unit that can be adjusted relative to the supporting unit. Background technique [0002] During the operation of large construction machinery such as ground drilling equipment, a tipping moment may appear on the construction machinery. Such a tipping moment can be caused statically by a projecting load, for example, but can also be caused dynamically, for example, by centrifugal force. [0003] In order to prevent the occurrence of excessive tilting moments, known practices include limiting the adjustment path of the outwardly extending load. However, this often leads to restrictions on the operating range of construction machinery and thus to restrictions on the application possibilities of construction machinery. Summary of the invention [0004] The purpose of the present invention is to provide a saf...
