A personal safety system for lifting material or supporting person therefrom includes a base and a mast rotatably coupled to the base. The mast has a plurality of mast sections that telescope relative to each other along an axis such that the mast is movable into and between a lowered configuration and an extended configuration. A jib is coupled to the mast and a cable is coupled to the jib such that a cable is configured to couple to the material or the person such that the system is capable of lifting the material or supporting the person. An attachment device coupled to the base is configured to permit a vehicle to couple to the system via the attachment device.

A mobile crane includes: a lower traveling body including a pair of crawlers; an upper slewing body supported on the lower traveling body slewably about a slewing axis; a tiltable attachment including a boom tiltably supported on the upper slewing body; and a physical quantity detector. The lower traveling body has a reaction force receiving part for receiving a reaction force from the ground at a position away from the slewing axis in a boom direction in a state where the pair of crawlers are in contact with the ground, the boom direction coinciding with a horizontal component of a direction in which the boom extends from the upper slewing body, and the physical quantity detector detects a physical quantity which changes in accordance with a change in the reaction force received from the ground by the reaction force receiving part.

This disclosure relates to a drivable working machine, including a vehicle, a concrete placing boom that can be rotated on a vehicle-fixed carrying structure by means of a slewing gear, and a plurality of supporting legs arranged on the carrying structure for supporting the carrying structure in a working position. A compensation device is provided to compensate a rotational deflection of the carrying structure from the working position. The compensation device has a sensing unit for sensing the rotational deflection and acts on at least one supporting leg by means of an associated actuator to reduce the rotational deflection.

The present invention relates to a mobile machine, in particular a crawler crane, comprising: an undercarriage with a tracklaying gear, and an uppercarriage which is rotatably mounted with respect to the undercarriage, wherein the tracklaying gear includes two crawler supports aligned parallel to each other, along whose longitudinal direction a crawler chain each is movably arranged, wherein one cantilever arm each is provided on the inner sides of the crawler supports facing each other, and at the distal end of the respective cantilever arm a support cylinder is arranged.
