The disclosure relates to a system for monitoring wind influences on a working machine, such as a mobile crane or crawler crane, comprising at least one detection unit that is arranged on the working machine and by means of which a current wind speed can be detected, a recording unit that is configured to receive, to store, and to transmit data of the detection unit during and outside the operation of the working machine, a controller of the working machine that is configured to determine a current working machine state, an external processing unit that is configured to directly or indirectly receive and process data from the detection unit relating to an current wind speed and data from the controller, and an output device that is configured to receive data from the external processing unit.

System for monitoring wind influences on a working machine

The present disclosure relates to a mobile crane, which comprises a superstructure, a main boom, which extends away from the superstructure and is arranged so as to be pivotable thereon, a derrick boom, which extends away from the superstructure and is arranged so as to be pivotable thereon, and a winch assembly, wherein the winch assembly comprises a main-boom winch for actuating the main boom and a derrick-boom winch for actuating the derrick boom. The mobile crane is characterised by an assistance apparatus for facilitating or fully automatically carrying out a raising and/or setting-down process of the derrick boom, which apparatus is designed to actuate the main boom and the derrick boom, such as the main-boom winch and the derrick-boom winch, at the same time.

Mobile crane comprising a device for facilitating or fully automatically carrying out a raising and/or setting-down process of a derrick boom, and corresponding method

The present disclosure relates to a lifting device, in particular a mobile crane or a cable-operated excavator, that comprises a superstructure, a main boom that starts from the superstructure, a luffing boom that starts from the end of the main boom remote from the superstructure, a winch arrangement, and a tilting moment detection unit for determining the tilting moment acting on the lifting device by the position of the main boom and the luffing boom. The disclosure is characterized by an apparatus for assisting or for fully automatic carrying out an erecting and/or placing down procedure of a boom system comprising the main boom and the luffing boom that is configured to carry out the steps for erecting and/or placing down the boom system in dependence on the tilting moment detected by the tilting moment detection unit.

Lifting device having an apparatus for assisting or for fully automatically carrying out an erection or placing down procedure of a boom system and corresponding method

The invention relates to a lifting device, in particular a mobile crane or a cable-operated excavator, having an apparatus for monitoring the raising and lowering procedures of a boom system of the lifting device.

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.

Mobile machine

Reachstacker

The present application relates to a mobile conveying vehicle comprising axles rigidly arranged on a support frame, an operator's cabin and a series of units and additional unit parts such as an engine, pumps, a radiator, hydraulic tank and/or fuel tank. In accordance with the application, the operator's cabin and the units with additional unit parts are mounted on a common frame construction. The frame construction is uncoupled from the support frame.
