The invention relates to a mast element, in particular a leader element, for a construction machine, with an elongate hollow mast profile which, at a front side, is provided along a mast longitudinal direction with two guide strips through which a linear guide for a mast carriage is formed along the front side. According to the invention, provision is made that at least one guide strip is designed as part of a guide profile on which at least one connection web is formed in one piece with the guide strip, which connection web extends away from the guide strip, and that, in order to form the hollow mast profile, elongate wall elements are provided which, together with the at least one connection web, form the hollow mast profile and enclose an inner cavity of the mast profile.

Mast element, in particular leader element, for a construction machine

The invention relates to a securing means and a method for securing a civil engineering element to a construction machine by means of a flexible securing element, wherein a first end of the flexible securing element is attached to the construction machine and a second end is provided with a connecting link which can pass through a securing lug on the civil engineering element and can be releasably fastened to the construction machine by a connecting means. According to the invention, a detection unit is provided on the connecting means, which detection unit is designed for identifying fastening of the connecting link to the connecting means. The detection unit can generate and output a signal if fastening of the connecting link is identified.

Securing means for securing a civil engineering element, and civil engineering method

A drilling unit, with a carrier vehicle, a mast rotatably mounted on the carrier vehicle about a pivot axis, which mast can be pivoted between an erect operating position and an inclined transport position, and at least one erection cylinder for pivoting the mast between the operating position and the transport position. For pivoting the mast in addition to the at least one erection cylinder an erection cable is provided which is guided via a cable deflection pulley arranged on the mast, on the carrier vehicle or on a carriage which can be moved along the mast, and in that in order to apply a pulling force to the erection cable via the cable deflection pulley an erection force can be transferred to the mast in the direction of its operating position. The invention further relates to a method for erecting a mast of a construction work unit.

Construction work unit and method for erecting a mast

The invention relates to a safety means for a construction machine having a carrier unit and an actuation unit, which is adjustable with respect to the carrier unit, comprising at least one detecting means for detecting the current position of the actuation unit relative to the carrier unit, an indication means with which the current position of the actuation unit relative to the carrier unit can be indicated, and an evaluation unit, by means of which, depending on at least one input value, at least one adjustment range of the actuation unit can be determined, in which the actuation unit is adjustable at a given safety against tilting of the construction machine, whereby the adjustment range can be indicated together with the current position of the actuation unit by means of the indication means.

Safety means for a construction machine

The invention relates to a construction machine having a carrier unit, an actuation unit, which is adjustable with respect to the carrier unit, at least one detecting means for detecting status data of the construction machine, and a computer unit, by means of which, based on the detected status data, at least one adjustment range of the actuation unit can be determined, in which the actuation unit is adjustable at a given safety against tilting of the construction machine. The invention also relates to a method for operating a construction machine of such type.
