The invention addresses the problem of providing a crane and a crane control method that can suppress load swaying when controlling an actuator on the basis of the load. The invention is provided with a turntable camera (7b) that detects the current position coordinates p(n) of a load W with respect to a reference position, wherein the invention: converts a target speed signal Vd to target position coordinates p(n+1) of the load W with respect to the reference position; calculates the current position coordinates q(n) of a boom (9) with respect to the reference position from a turning angle θz(n), a hoisting angle θx(n), and an extension/contraction length lb(n); calculates a feed amount l of the wire rope and the directional vector e(n) of the wire rope from the current position coordinates p(n) of the load W and the current position coordinates (n) of the boom (9); calculates the target position coordinates q(n+1) of the boom (9) with regards to the target position coordinates (n+1) of the load W from the feed amount l and the directional vector e(n) of the wire rope; and generates an actuator operation signal Md on the basis of the target position coordinates q(n+1) of the boom (9).

The invention relates to a mobile crane having a telescopic boom that is luffably coupled to a superstructure and that comprises a coupling section and at least one telescopic section supported therein in a retractable and extendable manner. At least one guying support is fastened to the coupling section and is connected to the coupling section or to the superstructure via a first guying and to a connection piece at a telescopic section via a second guying. In accordance with the invention, the second guying comprises at least two guying elements coupled with one another. The second guying is thereby adjustable in length and is thus adaptable to the extension length of the telescopic boom such that at least one of the mutually coupled guying elements is directly releasably connectable to the guying support. The invention further relates to a guying system for a mobile crane in accordance with the invention, to a method of moving a mobile crane in accordance with the invention into a guyed work position, and to a method of varying the extension length of the guyed telescopic boom of a mobile crane in accordance with the invention.

The disclosure relates to a mobile crane, such as a crawler crane, comprising an undercarriage having a traveling gear, a superstructure rotatably supported about a vertical axle on the undercarriage, a boom connected in an articulated manner to the superstructure pivotable about a horizontal axle, an A frame connected to the boom via a guying means, and a retraction mechanism by means of which the A frame is pivotable. In accordance with the disclosure, the A frame is separable and comprises a pole connected in an articulated manner to the superstructure and a folding pole releasably connected to the pole.

A crane for lifting and transporting loads includes a base frame for transferring the loads of the crane onto a support surface by a plurality of wheels. The wheels are capable of rotating relative to the base frame so as to change the camber angle of the wheels.

Provided is a crane with a main boom and a back mast, of which at least one comprises a first mast upper part comprising at least one mast section and a first mast lower part comprising at least one mast section, and a first mast tilting. The first mast tilting member is arranged between the first mast upper part and the first mast lower part, and has a straight hoisting state wherein the first mast upper part and the first mast lower part are essentially in line with each other, and a tilted hoisting state wherein the first mast upper part is tilted with respect to the first mast lower part.

A crane vehicle includes: an operation unit; a winch device configured to operate at a speed corresponding to an operation amount of the operation unit; a weight detection unit; a storage unit configured to store a time-weight target characteristic indicating a target in temporal change of a detected value at the weight detection unit for a maximum operation amount input from the operation unit; and a control unit configured to perform feedback control of an operation speed of the winch device such that the detected value follows the time-weight target characteristic in a case where the maximum operation amount is input from the operation unit, the control unit being configured to set the operation speed of the winch device at the speed corresponding to the operation amount of the operation unit, in a case where fluctuation of the detected value has converged in a predetermined range.

A crane, in particular a pick and carry crane, may have a front chassis with front wheels and a back chassis with back wheels, the front chassis being articulated relative to the back chassis so that the crane can travel whilst carrying a load suspended from a boom. The back and front wheels have independent suspensions which are capable of connection to one another so that movement of a left wheel influences movement of a right wheel, thereby improving the handing of the crane, particularly over rough terrain.

A crane arranged to be mounted to a vehicle and including a crane controller. The crane controller includes a machine learning algorithm, including a neural network trained to calculate a movements of a crane components based on a received trajectory instruction. A supervisory controller is provided arranged to evaluate the calculated movements by comparing an accuracy measure to a predefined safety margin. The accuracy measure is defined by the difference between a crane tip position resulting from the calculated movements when moved from a current position, and a position of the crane tip calculated by the supervisory controller, based on the received trajectory instruction and on positions of individual joints of said crane boom system, when moved from the current position, and to generate an overruling operating instruction for a system of actuators, in response to the accuracy measure being larger than the predefined safety margin.
